Visão Geral

Description

STTH30R04G is STMicroelectronics’ 30 A ultrafast recovery rectifier diode with a 400 V reverse voltage rating. The “G” suffix denotes RoHS-compliant (green) packaging. It is designed for fast switching in switch-mode power supplies, DC-DC converters, and freewheel/rectification in bridge configurations, where low recovery losses improve efficiency at high frequencies. The device comes in common packages (through-hole and surface-mount) and is offered in RoHS-compliant versions. For exact electrical characteristics (forward current rating, reverse-recovery time, forward voltage, surge current, and packaging), consult the ST data sheet.

Features

STTH30R04G is an ultrafast recovery rectifier diode. Key features:
- IF(AV) = 30 A (average rectified current)
- VRRM = 400 V (blocking/reverse voltage)
- Ultrafast recovery with very fast switching suitable for high-frequency rectification
- Low reverse-recovery charge (Qrr) for improved efficiency
- Low forward voltage drop at high current
- High surge/current capability for short-time peaks
- RoHS-compliant, lead-free (G suffix)
- Available in industry-standard packages (through-hole and surface-mount options)
Ideal for switch-mode power supplies, DC/DC converters, and free-wwheeling/rectification applications.

Pinout

STTH30R04G comes in a 3‑pin TO‑247 style package. Pin functions:
- Pin 1: Anode (A)
- Pin 2: Cathode (K)
- Pin 3: Cathode (K) — tied to the metal tab/heatsink (case)
Electrical connection: two terminals (Anode and Cathode); the tab/case is the cathode for heatsinking and low‑impedance connection.

Manufacturer

Manufacturer: STMicroelectronics.
What kind of company: STMicroelectronics is a multinational semiconductor company and integrated device manufacturer (IDM) that designs, develops and fabricates integrated circuits and discrete semiconductor components (including power diodes like the STTH30R04G). It is a global electronics supplier serving automotive, industrial, consumer and communications markets, with headquarters in Geneva, Switzerland.

Application

STTH30R04G is a 30 A ultrafast recovery rectifier (≈400 V rating). Typical application areas:
- Output rectification in high-frequency SMPS, adapters, and offline power supplies
- Freewheeling/rectification in flyback, buck/boost/forward converters
- Power-factor-correction stages and DC-DC conversion in telecom, computing, and consumer electronics
- Inverters, motor drives, UPS systems, and solar/wind inverters needing fast recovery and low switching losses
- Any high-speed rectification where compact size and efficiency are important in industrial and household power electronics

Package

The STTH30R04G is supplied in a TO-247 (3‑lead) plastic package.
