概述

Description

1N5349BRLG is a Zener diode in the 1N53xx family. It’s a low-power, 0.5 W device used to establish a stable reference voltage or to clamp voltage in circuits.
Key points:
- Zener voltage: nominally about 24 V (tolerance typically ±5% for the B version).
- Power rating: 0.5 W; maximum steady current around 20 mA (≈0.5 W / 24 V).
- Package: DO-41 axial leaded package.
- Suffix BRLG: RoHS-compliant / lead-free variant in the standard package.
- Typical use: voltage regulation references, over/under-voltage protection, and transient clamping in low-power electronics.
Note: exact VZ and parameters can vary by lot; always refer to the datasheet for precise values and recommended operating currents.

Features

1N5349BRLG is a Zener diode. Key features:
- Zener voltage: 9.1 V (nominal)
- Power rating: 0.5 W (500 mW)
- Tolerance: ±5% (B)
- Package: Axial, DO-41 style (RLG indicates leaded, RoHS‑compliant variant)
- Construction: Glass-passivated junction (high reliability)
- Applications: Voltage regulation, references, low-power regulation in circuits
- Operating range: Suitable for standard small-signal regulator roles in typical temperature ranges

Package

Axial through-hole package: DO-41 (through-hole, axial lead) Zener diode.

Pinout

- Pin count: 2 terminals (anode and cathode) on an axial package.
- Function: 1N5349B is a Zener diode with a nominal Zener voltage of about 9.1 V; used for voltage regulation/reference and reverse-bias clamping.
