Description

BAS40L is a dual Schottky barrier diode in a small SOT-23 style package. It’s used for high‑speed switching, low forward drop, and low leakage in compact circuits (e.g., logic, RF, protection, and rectification). The “L” variant denotes a specific dual-diode configuration in that family (exact pinout depends on the vendor).
315 is not a standard electrical spec. It’s most likely a date/lot or packaging/trace code used by the manufacturer or vendor. To be sure, check the exact datasheet for your BAS40L variant (e.g., BAS40L-xx) from your supplier; the datasheet will list Vr, If, Vf, and other electrical specs. If you share the vendor or a link, I can pull the precise numbers.

Equivalent

315 is just the date code. BAS40L is a dual switching diode in SOT-23; exact equivalents depend on the pinout (common cathode vs. common anode). Common cross-references (same footprint) are:
- BAV99 (dual switching diodes, SOT-23)
- MMBD4148 (dual, SMD variants LL4148/1N4148W)
Please confirm the BAS40L pinout/package you have to give precise substitutes.

Features

Short features of BAS40L (dual Schottky diodes in one package, SOT-23):
- Dual Schottky barrier diodes (common cathode in most BAS40L variants)
- Package: SOT-23, 3 leads
- Reverse voltage: around 40 V per diode
- Maximum forward current (per diode): typically ~200 mA
- Low forward voltage drop: ~0.2–0.3 V at moderate currents
- Very fast switching (no minority-carrier storage)
- Low leakage current (increases with temperature)
- Low junction capacitance (suitable for high-speed/high-frequency use)
- Wide operating temp range: typically -55 to +125 °C
- RoHS compliant (lead-free)
Note: exact pinout (common cathode/anode) and ratings can vary by lot/version; consult the specific datasheet for your BAS40L variant.

Pinout

- Pin count: 3 pins
- Function: Dual Schottky barrier diodes with a common cathode (two diodes share pin 3; pin 1 and pin 2 are the anodes). In BAS40L,315 the common pin is the cathode.

Manufacturer

BAS40L,315 isn’t tied to a single exclusive maker. It’s a common fast-switching diode produced by several vendors, notably Vishay Intertechnology and Nexperia (formerly Philips/NXP). The “315” is typically a date/lot code and doesn’t identify a unique manufacturer.
Both Vishay and Nexperia are global semiconductor companies that design and manufacture discrete components (diodes, transistors, etc.) and other electronic components used across many industries.

Application

BAS40L,315 is a dual Schottky diode (low forward drop, fast switching). Typical application areas:
- High-speed switching and diode-logic (OR-ing) in digital/CMOS circuits
- RF front-ends: detectors, mixers, envelope detectors, clamp circuits
- Input protection and level shifting for microcontrollers and logic interfaces
- Low-current rectification and freewheeling in switch-mode power supplies
- Pulse shaping, peak-detection, and waveform-clipping applications

Package

SOT-23-3 (3-pin) surface-mount package. The “315” is likely a date/lot code, not a package designation.
