Product details

Overview

SF62GHR0G from Taiwan Semiconductor is a 100 V, 6 A super fast recovery rectifier diode in DO-201AD package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 6 A/25°C, and 150 A surge capability - deployed in DC-DC converters and switching inverters for high-efficiency power conversion.

For engineers reviewing the SF62GHR0G datasheet, SF62GHR0G pinout, SF62GHR0G application, or SF62GHR0G equivalent, key selection criteria include repetitive peak reverse voltage (V_RRM = 100 V), thermal resistance (R_θJL = 5 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status.

Technical Context

This discrete silicon rectifier uses a single-die planar junction structure optimized for fast switching in high-frequency SMPS topologies. Its 35 ns trr and low Q_rr minimize switching losses during freewheeling and flyback phases.

The device operates with a maximum junction temperature of 150 °C and exhibits stable reverse leakage (<5 µA at 25 °C, <100 µA at 125 °C) across its rated 100 V V_RRM, supporting reliable operation in automotive-grade power supplies and industrial DC-DC modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in clamp/freewheeling circuits
I_F	6 A - Continuous average forward current; determines heatsink sizing and conduction loss budget
I_FSM	150 A - Non-repetitive surge rating (8.3 ms half-sine); supports inrush and fault-current tolerance
t_rr	35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequencies
V_F	0.975 V @ 6 A, 25°C - Forward voltage drop; directly impacts conduction loss (P_cond ≈ I_F × V_F)
R_θJL	5 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour thermal management without external heatsink
C_J	100 pF @ 1 MHz, 4 V - Junction capacitance; influences EMI generation and snubber design in high-dv/dt environments

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6L06S	V_RRM = 600 V, t_rr = 35 ns, V_F = 1.15 V @ 6 A - higher voltage rating but higher forward drop	Used in 400 V PFC front-ends; less optimal for 100 V-class DC-DC due to excess voltage margin and loss	Select when system requires >400 V blocking or legacy 600 V design reuse
ON Semi MUR620E	V_RRM = 200 V, t_rr = 35 ns, V_F = 0.92 V @ 6 A - lower V_RRM, slightly lower V_F, same package	Common in 24–48 V industrial SMPS; not AEC-Q101 qualified	Prefer for cost-sensitive non-automotive designs needing minimal V_F improvement

Compared with STTH6L06S and MUR620E, SF62GHR0G uniquely balances 100 V V_RRM, AEC-Q101 qualification, and 0.975 V V_F - making it the optimal choice for automotive 12/48 V DC-DC converters where reliability, thermal efficiency, and qualification compliance are jointly required.

FAQ

What is the peak repetitive reverse voltage rating for SF62GHR0G?

The SF62GHR0G has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version G2105), where SF62G is explicitly listed under the 100 V column. It defines the maximum reverse-biased voltage the device can block continuously without breakdown.

Is SF62GHR0G qualified to AEC-Q101 standards?

Yes, SF62GHR0G is AEC-Q101 qualified. The "H" suffix in the ordering code (SF62GHR0G) denotes AEC-Q101 qualification per the Ordering Information section of the TSC datasheet. This includes full stress testing for high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing.

What is the forward voltage drop of SF62GHR0G at 6 A and 25°C?

The forward voltage (V_F) of SF62GHR0G is 0.975 V at I_F = 6 A and T_J = 25°C, as specified in the Electrical Specifications table under "SF61G – SF64G" grouping. This value is measured using a 0.3 ms pulse width test condition and directly impacts conduction loss in power stage design.

Does SF62GHR0G have a halogen-free construction?

Yes, SF62GHR0G is halogen-free in accordance with IEC 61249-2-21. The datasheet states this under FEATURES and MECHANICAL DATA sections, confirming the molding compound contains no brominated or chlorinated flame retardants - supporting compliance with green electronics initiatives.

What is the reverse recovery time (t_rr) specification for SF62GHR0G?

The reverse recovery time (t_rr) for SF62GHR0G is 35 ns maximum, tested at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is consistent across the SF61G–SF64G group and enables high-frequency switching in DC-DC converters up to ~500 kHz with low switching loss.
