Product details

Overview

SFT13GHR0G from Taiwan Semiconductor is a 150 V, 1 A super fast recovery rectifier diode in TS-1 package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A and 25 °C, and 30 A surge current capability; used in DC-DC converters and freewheeling paths in automotive-grade switching power supplies.

For engineers reviewing the SFT13GHR0G datasheet, SFT13GHR0G pinout, SFT13GHR0G application, or SFT13GHR0G equivalent, key selection criteria include V_RRM = 150 V, I_F = 1 A, t_rr = 35 ns, V_F = 0.95 V, and AEC-Q101 qualification status - all confirmed for this exact marking variant.

Technical Context

This super fast rectifier employs a single-die planar junction structure optimized for low conduction loss and rapid carrier recombination. Its 35 ns reverse recovery time enables high-frequency operation up to ~500 kHz in hard-switched topologies while maintaining low EMI generation.

The TS-1 package provides 100 °C/W junction-to-ambient thermal resistance and supports lead-free soldering per J-STD-002. Cathode polarity is marked by a visible band; device weight is 0.200 g.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in flyback/clamp circuits
I_F	1 A continuous - average forward current rating at 75 °C ambient; sets baseline conduction capability
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables efficient high-frequency switching
V_F	0.95 V @ 1 A, 25 °C - low forward drop reduces conduction loss and improves system efficiency
I_FSM	30 A - non-repetitive surge rating (8.3 ms half-sine); withstands inrush and fault transients
C_J	20 pF @ 1 MHz, 4 V - low junction capacitance minimizes switching loss and ringing in high-dV/dt environments
T_J max	150 °C - maximum junction temperature; supports operation in under-hood automotive environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	V_RRM = 600 V, t_rr = 50 ns, V_F = 1.15 V @ 1 A - higher voltage rating but slower recovery and higher drop	Preferred where 600 V standoff is required (e.g., PFC front-end), not optimal for 150 V, high-frequency use	Select SFT13GHR0G when 150 V rating, 35 ns speed, and 0.95 V V_F are critical for efficiency in compact converters
ES1D-E3/54	V_RRM = 200 V, t_rr = 35 ns, V_F = 0.93 V @ 1 A - same speed, slightly lower V_F, but not AEC-Q101 qualified	Suitable for commercial/industrial designs without automotive qualification mandates	Choose SFT13GHR0G for automotive applications requiring AEC-Q101; ES1D-E3/54 may be used where qualification is not required

Compared with STTH1R06 and ES1D-E3/54, SFT13GHR0G uniquely combines 150 V rating, 35 ns t_rr, 0.95 V V_F, and AEC-Q101 qualification - making it the optimal choice for space-constrained, high-efficiency automotive DC-DC freewheeling where voltage margin and qualification are jointly critical.
