概述

Description

STTH1003SB-TR is an ultrafast recovery rectifier diode from STMicroelectronics (STTH100x family). It’s designed for high‑speed rectification in switched‑mode power supplies and other power‑electronics applications.
Key points:
- Ultrafast recovery with low reverse‑recovery losses
- Suitable for high forward current and surge conditions
- High reverse‑voltage capability for mid/high‑voltage rectification
- Robust for SMPS, PFC, and DC‑DC converter stages
- -TR suffix indicates tape‑and‑reel packaging for automated assembly; -SB is a variant code in the part number. Exact ratings (IF(AV), VRRM, trr, VF, IFRM) depend on the specific device variant—consult the datasheet for precise values.
Typical uses:
- Rectification in SMPS
- Freewheeling/rectification in buck/boost converters
- Power‑factor correction networks
How to use:
- Match VRRM and IF(AV) to your circuit, consider thermal management, and follow proper mounting/heat‑sink guidelines.
For exact electrical specs and packaging details, refer to the ST datasheet or an authorized distributor.

Package

The STTH1003SB-TR uses a surface-mount SMA (DO-214AC) plastic package; -TR denotes Tape & Reel packaging.

Pinout

- Pin count: 2
- Function: Ultrafast recovery rectifier diode (STTH series) for high-speed rectification; Pin 1 = Anode, Pin 2 = Cathode.

Manufacturer

Manufacturer: STMicroelectronics.
What kind of company: STMicroelectronics is a Franco‑Italian multinational semiconductor manufacturer (headquartered in Geneva) that designs, develops and produces a broad range of semiconductor products and discrete components—power diodes/transistors, analog and mixed‑signal ICs, microcontrollers (e.g. STM32), sensors and MEMS—for automotive, industrial, consumer and communications markets.

Application

STTH1003SB-TR is a high-voltage fast-recovery rectifier diode. Common applications include:
- Switch-mode power supplies (SMPS), PFC and DC-DC converters
- Freewheeling/rectifier diodes in bridge or half-bridge topologies
- Power inverters and motor-drive systems
- Solar inverters and battery charging circuits
- Uninterruptible power supplies (UPS) and telecom power modules
- High-frequency rectification in consumer/industrial SMPS
