Übersicht

Description

1N5349BRLG is a Zener diode in the 1N5349B series.
Key points:
- Zener voltage (nominal): 9.1 V
- Power rating: about 0.5 W (0.5 watt)
- Package: axial DO-41; “RLG” is a vendor-specific suffix indicating leaded/RoHS-compliant packaging
- Tolerance: typically ±5% (B)
- Primary use: voltage regulation/reference and transient/overvoltage protection in low-power circuits
- How it’s used: reverse-biased with a series resistor to set current in the Zener region
Note: exact parameters (Izt, Zzt, leakage, tempco) vary by manufacturer and lot. Check the specific datasheet for the vendor of 1N5349BRLG to confirm Izt, Zzt, and operating conditions.

Equivalent

I don’t have live datasheet access. Please confirm the 1N5349BRLG’s zener voltage, power rating and package (or paste the datasheet/marking). Once you provide that I’ll list exact equivalent parts.

Features

- Type: Zener diode
- Nominal Zener voltage: 9.1 V
- Power rating: 1 W
- Package: Through-hole axial DO-41
- Construction: Glass-passivated junction for high reliability and low leakage
- Tolerance: Typically ±5%
- Temperature stability: Suitable for simple regulation/reference roles in DC circuits
- Applications: Voltage regulation, voltage references, transient/surge protection
- Compliance: RoHS lead-free variant (suffix LG indicates lead-free)

Pinout

Pin count: 2 (anode and cathode).
Function: It is a Zener diode (part of the 1N53xx series) used as a voltage reference/clamp for regulation and transient protection. The exact nominal Zener voltage, power rating and package details (axial DO‑41/DO‑204AL style) should be confirmed from the manufacturer's datasheet.

Manufacturer

Manufacturer: Vishay Intertechnology (Vishay).
What kind of company: A global manufacturer of electronic components, including discrete semiconductors (diodes, zeners, transistors) and passive components (resistors, capacitors, inductors) used in a wide range of industries.

Application

1N5349BRLG is a 9.1 V Zener diode (1 W, axial DO-41). Common applications:
- Voltage regulation and reference in power supplies and regulator circuits
- Stable reference for comparators, op-amps, and ADCs
- Zener clamp to protect inputs and limit signal swings
- Simple shunt regulator in low-to-medium power devices
- Transient/spike suppression and overvoltage protection in consumer electronics

Package

It's an axial through-hole Zener in a DO-41 package. The BRLG suffix indicates a RoHS-compliant, lead-free variant.
