概述

Description

SZ1SMA15CAT3G appears to be a catalog part number for a power diode in an SMA (DO-214AC) package. The middle “SMA” indicates the package type; the “15” and “C” likely encode current/voltage or speed, and “T3G” is a lot/grade code. Without the manufacturer’s datasheet, exact ratings and pinout can’t be confirmed.
What it generally implies:
- Package: SMA (DO-214AC), suitable for power rectification or fast switching.
- Typical roles: rectifier in power supplies, freewheeling/protection diode in converters.
- Key specs to verify: repetitive reverse voltage (VR), forward current (IF), forward voltage (VF), recovery speed (if a fast diode), and junction temperature (Tj).
How to get precise details:
- Look up the exact code on the manufacturer’s site or distributor databases (Digi-Key, Mouser, Arrow).
- Open the datasheet for pinout, electrical characteristics, package outline, and PCB footprint.

Package

It’s in an SMA (DO-214AC) surface-mount package.

Pinout

Pin count: 2 pins. Function: Two-terminal Transient Voltage Suppressor (TVS) diode in an SMA package, used for surge/ESD overvoltage protection.

Application

SZ1SMA15CAT3G is a 15 V SMA-packaged TVS diode with Cat 3 surge capability. Applications:
- Transient/over-voltage protection for low-voltage rails (12–24 V) and DC/DC converters
- Protection of microcontrollers, ICs, and power supplies from surges and ESD
- Interface protection for automotive, industrial, and consumer electronics
- Data/communication lines (CAN/LIN, USB, Ethernet, telecom) against transient events
