Product details

Overview

SF62G from Taiwan Semiconductor is a 6A, 100V super fast rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 0.975V forward voltage at 6A/25°C, and 150A surge capability - deployed in DC-DC converters and switching inverters requiring low-loss freewheeling.

For engineers reviewing the SF62G datasheet, SF62G pinout, SF62G application, or SF62G equivalent, key selection criteria include V_RRM=100V, I_F=6A, t_rr=35ns, R_θJL=5°C/W, and DO-201AD mechanical compatibility with high-reliability power conversion designs.

Technical Context

This super fast rectifier uses a single-die silicon PN junction optimized for high-frequency switching operation. Its 35ns reverse recovery time and low 0.975V forward voltage at rated current enable efficient energy transfer in hard-switched topologies.

Thermal performance is defined by 5°C/W junction-to-lead resistance and 40°C/W junction-to-ambient rating, supporting continuous 6A conduction up to +150°C junction temperature under proper heatsinking.

V_RRM	100 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 100V bus applications
I_F	6 A - Continuous forward current rating; defines steady-state power handling without derating
t_rr	35 ns - Reverse recovery time; enables stable operation up to ~3 MHz switching frequencies
V_F	0.975 V @ 6A, 25°C - Low conduction loss; reduces thermal load in high-duty-cycle converters

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6L06D (STMicroelectronics)	V_RRM=600V, t_rr=35ns, V_F=1.15V @ 6A - higher voltage rating but higher forward drop	Used in 400V+ PFC stages; less optimal for 100V bus due to over-spec'd V_RRM and higher loss	Select when system requires 600V margin or shares BOM with higher-voltage variants
ES6D (ON Semiconductor)	V_RRM=200V, t_rr=35ns, V_F=0.92V @ 6A - lower V_F, wider voltage grade, same package	Common in universal-input offline SMPS; suitable where 200V rating adds safety margin without penalty	Prefer when designing for global input ranges or needing tighter V_F tolerance

Compared with STTH6L06D and ES6D, the SF62G offers the optimal balance of 100V rating, 0.975V V_F, and DO-201AD footprint for cost-sensitive 12–48V DC-DC systems - avoiding over-engineering while maintaining thermal headroom and recovery speed.

FAQ

What is the maximum junction temperature rating for SF62G?

The SF62G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official TSC datasheet Version G2105. This rating applies under continuous forward conduction at 6A with appropriate thermal management. Operation beyond this limit risks irreversible degradation of the silicon die and packaging integrity. The SF62G must be mounted on sufficient copper area or heatsink to maintain T_J ≤150°C in actual application conditions.

Is SF62G pin-compatible with other DO-201AD rectifiers like SF61G or SF63G?

Yes, SF62G shares identical DO-201AD mechanical dimensions, lead spacing, and polarity marking (cathode band) with SF61G through SF68G. All members of the SF6xG family use the same package outline and mounting footprint. However, electrical parameters differ - SF62G is rated for 100V V_RRM, while SF61G is 50V and SF63G is 150V - so substitution requires verification of voltage margin and thermal performance in the target circuit.

Does SF62G meet automotive qualification standards?

The base SF62G is not AEC-Q101 qualified, but the variant SF62GH is explicitly certified to AEC-Q101. Per TSC's ordering information, the "H" suffix denotes AEC-Q101 qualification, including stress testing for temperature cycling, humidity bias, and mechanical shock. For automotive under-hood or ADAS power supply designs, SF62GH - not SF62G - must be specified and sourced.

What is the typical reverse recovery time (t_rr) of SF62G and how is it measured?

The SF62G has a typical reverse recovery time (t_rr) of 35 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as specified in the TSC SF6xG datasheet Version G2105. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss and EMI in high-frequency converters. It is validated using standardized test circuits shown in Figure 6 of the datasheet.

How does the forward voltage (V_F) of SF62G compare across temperature and current?

The SF62G exhibits V_F = 0.975 V at I_F = 6 A and T_J = 25°C, rising to approximately 1.15 V at T_J = 125°C under same current. This positive temperature coefficient improves current sharing in parallel configurations. The value is confirmed in the Electrical Specifications table of the TSC datasheet and aligns with typical silicon super fast rectifier behavior - critical for accurate thermal modeling in high-power DC-DC designs using SF62G.
