STMicroelectronics STTH16003TV1

Overview

STTH16003TV1 from STMicroelectronics is a dual ultra-fast soft-recovery rectifier in ISOTOP package, rated for 300 V repetitive peak reverse voltage and 2 × 60 A average forward current per diode, with 80 ns typical reverse recovery time and 0.95 V typical forward voltage at 125 °C - designed for high-frequency secondary-side rectification in telecom power supplies and welding equipment.

For engineers reviewing the STTH16003TV1 datasheet, STTH16003TV1 pinout, STTH16003TV1 application, or STTH16003TV1 equivalent, key selection criteria include soft recovery behavior (Sfactor = 0.3), 2500 V_rms insulation rating, low junction-to-case thermal resistance (0.7 °C/W per diode), and dual-diode layout enabling interleaved conduction in DC–DC converters.

Technical Context

This dual rectifier integrates two independent ultra-fast diodes in a single insulated ISOTOP housing, sharing a common heatsink interface but electrically isolated between anode-cathode pairs. Its soft recovery (Sfactor = 0.3) minimizes EMI during turn-off, while low capacitance (<45 pF) and low inductance simplify PCB layout in high-dV/dt environments.

The device operates up to 150 °C junction temperature and supports surge currents up to 800 A (10 ms sine), with thermal coupling resistance of 0.1 °C/W enabling accurate thermal modeling when both diodes conduct simultaneously in phase-shifted topologies.

Key Specifications

FAQ

What is the maximum allowable case temperature for continuous operation?

The device is rated for T_c = 85 °C at I_F(AV) = 60 A per diode. Exceeding this requires derating per Figure 1 in the datasheet; at T_c = 100 °C, maximum I_F(AV) drops to ~48 A per diode due to thermal resistance limits and junction temperature cap of 150 °C.

Can STTH16003TV1 be used in synchronous rectification topologies?

No - it is a passive silicon PN junction rectifier, not a MOSFET-based synchronous device. It lacks gate control and cannot be actively switched; its role is strictly unidirectional conduction with inherent recovery timing, making it suitable only for conventional or quasi-resonant rectification.

How does the ISOTOP package achieve 2500 V_rms insulation?

The ISOTOP uses a molded epoxy barrier between the metal base and internal die attach, with creepage/clearance distances validated per IEC 60664-1. The 2500 V_rms rating is measured between all terminals and the isolated metal base, confirmed via factory hi-pot testing at 3500 V DC for 1 minute.

Is lead-free soldering compatible with the ISOTOP package?

Yes - STTH16003TV1 carries ECOPACK® certification with lead-free second-level interconnect. It supports standard Pb-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260 °C for 10 seconds, with no delamination or bond lift observed in qualification testing.
