Product details

Overview

SF1604PTHC0G from Taiwan Semiconductor is a dual-die, positive-center-tap super fast rectifier in TO-247AD package, rated for 200 V repetitive peak reverse voltage (V_RRM), 16 A average forward current (I_F), and 35 ns reverse recovery time (t_rr). It delivers low forward voltage (0.95 V at 8 A, 25°C) and high surge capability (150 A I_FSM), enabling efficient freewheeling and snubber functions in high-frequency switching power supplies.

For engineers reviewing the SF1604PTHC0G datasheet, SF1604PTHC0G pinout, SF1604PTHC0G application, or SF1604PTHC0G equivalent, key selection criteria include its AEC-Q101 qualification, dual-diode center-tap configuration, thermal resistance (2°C/W), UL recognition (E-326243), and halogen-free compliance per IEC 61249-2-21.

Technical Context

This device integrates two identical silicon die in a single TO-247AD package with shared cathode connection and isolated anodes-enabling center-tapped full-wave rectification without external wiring. Its glass-passivated junctions and optimized doping profile support stable operation up to 150°C junction temperature while maintaining sub-1 V forward drop and <35 ns recovery.

The SF1604PTHC0G is specified for 200 V V_RRM (with 140 V rms rating), exhibits 10 µA max reverse leakage at 25°C, and achieves 85 pF junction capacitance per diode at 4 V reverse bias-critical for minimizing switching losses and EMI in DC/DC converters operating above 100 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports input rectification in 12–48 V output SMPS with 2× safety margin against line transients
I_F	16 A - continuous conduction mode operation in 300–500 W power stages without forced cooling
t_rr	35 ns - enables >200 kHz switching frequency with minimal reverse recovery loss and diode ringing
V_F	0.95 V @ 8 A, 25°C - reduces conduction loss to <7.6 W per diode at rated current, improving system efficiency
R_θJC	2°C/W - allows 130°C temperature rise at 150 W dissipation, supporting compact heatsink designs
I_FSM	150 A @ 8.3 ms - withstands inrush and fault currents in industrial motor drives and UPS systems

FAQ

What is the maximum junction temperature rating for SF1604PTHC0G?

The SF1604PTHC0G has a maximum junction temperature (T_J) of +150°C, validated across its full operating range from –55°C to +150°C. This rating is supported by its 2°C/W junction-to-case thermal resistance and glass-passivated chip construction, allowing sustained operation in high-ambient environments such as engine compartments or enclosed industrial enclosures when properly heatsinked.

Is SF1604PTHC0G pin-compatible with other parts in the SF1601PT–SF1608PT series?

Yes, all SF1601PT through SF1608PT variants-including SF1604PTHC0G-share identical TO-247AD (TO-3P) mechanical footprint, pinout, and terminal assignment (A1, A2, K). Voltage ratings differ across the series (50–600 V), but PCB layout, mounting hardware, and thermal interface design remain fully interchangeable.

Does SF1604PTHC0G meet automotive reliability standards?

Yes, the "H" suffix in SF1604PTHC0G denotes AEC-Q101 qualification, confirming compliance with stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias. It is approved for use in automotive power supplies, body control modules, and infotainment systems where extended life and failure-mode robustness are required.

What is the reverse recovery time specification for SF1604PTHC0G?

The SF1604PTHC0G has a maximum reverse recovery time (t_rr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed across the full temperature range and enables clean commutation in hard-switched topologies operating up to 300 kHz without significant tail current loss or voltage overshoot.

How does the center-tap configuration of SF1604PTHC0G simplify circuit design?

The SF1604PTHC0G integrates two matched super fast diodes with a common cathode terminal (K) and separate anodes (A1, A2), forming a positive center-tap rectifier. This eliminates external wiring between discrete diodes, reduces parasitic inductance, ensures matched dynamic performance, and simplifies transformer secondary termination in forward, push-pull, and half-bridge DC/DC converters.
