Taiwan Semiconductor Corporation SF1602PTH

Overview

SF1602PTH from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD (TO-3P) package, rated for 100 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), high surge capability (150 A I_FSM), and is AEC-Q101 qualified for automotive-grade reliability in snubber and freewheeling roles.

For engineers reviewing the SF1602PTH datasheet, SF1602PTH pinout, SF1602PTH application, or SF1602PTH equivalent, key selection criteria include its 100 V V_RRM, dual-center-tap configuration, AEC-Q101 qualification, TO-247AD thermal performance (R_θJC = 2°C/W), and verified use in switching-mode DC/DC converters requiring fast recovery and low conduction loss.

Technical Context

This device integrates two identical silicon die in a single TO-247AD package with shared cathode and isolated anodes-enabling center-tapped full-wave rectification without external wiring. Its glass-passivated junctions ensure stable operation up to 150°C junction temperature and support high-reliability automotive and industrial power conversion.

The 35 ns reverse recovery time and 0.95 V forward voltage at 8 A are measured under standardized pulse conditions (PW = 0.3 ms), confirming suitability for high-frequency switching topologies where diode switching loss and conduction loss must both be minimized simultaneously.

FAQ

What is the maximum junction temperature rating for SF1602PTH?

The SF1602PTH has a maximum junction temperature (T_J) rating of +150°C, validated across its full operating range from –55°C to +150°C. This rating is supported by its glass-passivated junction and TO-247AD package with 2°C/W junction-to-case thermal resistance. Derating curves in the official TSC datasheet confirm 16 A I_F is sustainable up to 100°C case temperature, making SF1602PTH suitable for under-hood automotive applications where ambient temperatures exceed 105°C.

Is SF1602PTH pin-compatible with other devices in the SF160xPT family?

Yes, all SF160xPT and SF160xPTH devices-including SF1602PTH-share identical TO-247AD (TO-3P) mechanical outline, pin assignment (A1/A2/K), and marking format. Voltage variants (SF1601PTH to SF1608PTH) differ only in V_RRM (50–600 V) and corresponding forward voltage; thus, SF1602PTH can be substituted with SF1603PTH or SF1604PTH in layouts where higher blocking voltage is acceptable, provided thermal and electrical margins remain sufficient.

Does SF1602PTH require a heatsink in typical 16 A operation?

SF1602PTH requires a heatsink when operating continuously at or near its 16 A I_F rating, due to power dissipation exceeding 15 W (based on 0.95 V × 16 A). With its R_θJC = 2°C/W, even a modest 10°C/W heatsink yields ~140°C junction rise above ambient-exceeding the 150°C limit. A properly sized heatsink (≤5°C/W thermal resistance) or forced airflow is recommended for sustained 16 A loads, especially in enclosed or high-ambient environments.

What does the "H" suffix in SF1602PTH signify?

The "H" suffix in SF1602PTH explicitly denotes AEC-Q101 qualification per revision G2103 of the product specification. This includes extended temperature cycling, high-temperature operating life (HTOL), and unbiased highly accelerated stress test (uHAST) validation. Unlike standard SF1602PT, SF1602PTH undergoes additional screening and lot-level traceability to meet automotive component reliability requirements-making it suitable for safety-critical power systems in ADAS, body control, and infotainment modules.

How is the reverse recovery time (t_rr) of SF1602PTH measured and what circuit conditions apply?

The reverse recovery time (t_rr) of SF1602PTH is measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per JEDEC standard test conditions. The value of 35 ns is the maximum specified in the datasheet and reflects worst-case behavior under these defined conditions. This measurement uses a standardized test circuit with controlled di/dt and dv/dt, ensuring reproducibility across labs. Designers should reference Figure 6 in the TSC datasheet for exact waveform definitions and test setup details applicable to SF1602PTH.
