概述

Description

STTH30R04G is STMicroelectronics’ 30 A, 400 V ultrafast rectifier diode (STTH family). It is designed as a high-speed rectifier for switching power supplies, DC-DC converters, PFC stages, and other SMPS applications, where fast recovery reduces switching losses.
Key points:
- Vr = 400 V; If(AV) = 30 A
- Ultrafast reverse-recovery with low recovery charge for efficient operation
- Suitable for high surge currents and rugged operation
- G suffix typically indicates RoHS-compliant (lead-free) packaging
- Available in common power-package formats for both through-hole and surface-mount designs
Use it as a freewheeling/rectifier diode in PWM converters, inverters, and other high-frequency rectification stages. For exact packaging, thermal limits, and precise tRR values, consult the ST datasheet for STTH30R04G.

Features

STTH30R04G features (concise):
- 30 A average rectified current (IF(AV) = 30 A)
- 400 V repetitive reverse voltage (VRRM)
- Ultrafast recovery diode with short reverse-recovery time
- Low reverse-recovery energy and soft recovery
- High peak surge current capability (I_FSM in the hundreds of amps)
- Low forward voltage drop for high efficiency
- High dV/dt capability for switch-mode/rectifier use
- Pb-free, RoHS compliant
- Package: TO-220AB (G) style for easy mounting and power dissipation
Note: for exact t_rr, I_FSM, and operating temperature range, refer to the datasheet.

Package

TO-220AB package (through-hole). The “G” indicates a lead-free/green version of the STTH30R04G.

Pinout

- Pin count: 2 leads (anode and cathode; the package tab is tied to the cathode).
- Function: Ultrafast recovery rectifier diode used for high-speed rectification in power supplies (30 A, ~400 V class).

Manufacturer

- Manufacturer: STMicroelectronics (ST)
- What kind of company: A multinational European semiconductor company that designs, manufactures, and markets integrated circuits and discrete devices (e.g., diodes, transistors).

Application

Applications: switch-mode power supplies (SMPS) rectification and freewheeling diodes; PFC circuits; DC–DC converters and inverter/motor-drive stages; renewable-energy inverters (solar, wind); uninterruptible power supplies (UPS) and telecom rectifiers; welding equipment and other industrial power electronics.
