개요

Description

STTH30R04G-TR is an ultrafast recovery rectifier diode from STMicroelectronics. Key specs: 30 A average forward current (Io) and a repetitive peak reverse voltage (VRRM) of 400 V. Designed for high-frequency rectification in switch‑mode power supplies and power-conversion circuits, it offers fast reverse-recovery time and good surge current capability with rugged construction. The “-TR” suffix indicates a Tape-and-Reel packaging option for automated assembly. Typical applications include secondary-side rectification in flyback/forward converters, freewheeling diodes in buck/boost regulators, and PFC stages. For exact electrical characteristics (IF(AV), VF, trr, thermal data), refer to the ST datasheet.

Features

STTH30R04G-TR is a 30 A ultrafast rectifier rated for 400 V. Key features:
- Io = 30 A average rectified current
- VRRM = 400 V reverse voltage
- Ultrafast recovery diode for low switching losses
- Low forward voltage drop (typical around 1.0–1.2 V at rated current)
- High surge current capability for rectification in SMPS
- Fast recovery reduces EMI and improves efficiency
- Wide operating temp range up to ~150°C junction temperature
- RoHS compliant, lead-free
- ST packaging with Tape & Reel (TR) option for automated assembly
Applications: switch-mode power supplies, freewheeling/ snubber circuits, and other high-speed rectification needs.

Package

TO-220AB through-hole package, Pb-free, supplied in Tape & Reel (TR).

Pinout

Pin count: 2 electrical pins (anode and cathode; the package tab is typically connected to the cathode).
Function: Ultrafast recovery rectifier diode (STTH30R04G) rated about 30 A and 400 V, used for high-speed rectification in switch-mode power supplies.

Manufacturer

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A multinational semiconductor company that designs, manufactures, and markets a wide range of ICs and discrete components (diodes, transistors, MOSFETs, etc.). It’s one of the world’s largest semiconductor manufacturers, headquartered in Geneva, Switzerland (originating from the merger of SGS Microelettronica and Thomson Semiconductors).

Application

STTH30R04G-TR is a 30 A ultrafast recovery diode (around 400 V class). Typical application areas:
- High-frequency SMPS and PFC stages
- DC-DC converters (buck/boost) and point-of-load regulators
- Freewheeling/rectification in motor drives and inverters
- UPS and energy-storage converters
- Solar/grid-tied inverters and telecom power supplies
- Welding/induction heating power electronics
Note: used as fast-recovery rectifier or freewheel diode in fast switching circuits.
