Product details

Overview

SF1002G from Taiwan Semiconductor is a 10A, 100V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 5A/25°C, and 125A surge capability - used in DC-DC converters and switching inverters for high-efficiency power conversion.

For engineers reviewing the SF1002G datasheet, SF1002G pinout, SF1002G application, or SF1002G equivalent, key selection criteria include V_RRM=100V, I_F=10A, t_rr=35ns, R_θJC=3.5°C/W, and AEC-Q101 qualification availability (SF1002GH variant).

Technical Context

This super fast rectifier uses dual-die construction in a single TO-220AB package with common-cathode configuration. Its 35ns reverse recovery time and low 0.975V forward voltage at 5A enable reduced switching losses in high-frequency SMPS topologies.

Thermal performance is defined by a junction-to-case resistance of 3.5°C/W, supporting continuous 10A operation with appropriate heatsinking. The device operates across -55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance.

Key Specifications

V_RRM	100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths
I_F	10 A - Continuous average forward current; determines heatsink sizing and conduction loss budget
t_rr	35 ns - Reverse recovery time; critical for minimizing switching loss and EMI in >50kHz converters
V_F	0.975 V @ 5A, 25°C - Forward voltage drop per diode; directly impacts conduction loss and thermal design
R_θJC	3.5 °C/W - Junction-to-case thermal resistance; enables calculation of case temperature rise under load
C_J	70 pF @ 1MHz, 4V - Junction capacitance per diode; affects high-frequency switching behavior and snubber design
I_FSM	125 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and fault-current handling

Pinout & Package

TO-220AB package with center-tab cathode configuration: Pin 1 (Anode 1), Pin 2 (Cathode common), Pin 3 (Anode 2). Matte tin-plated leads meet J-STD-002 solderability; polarity marked on device body.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode 1	Input terminal for first diode leg; connects to high-side switch node in dual-output or interleaved designs
Pin 2	Cathode (common)	Shared output node; requires low-inductance connection to ground/power rail for optimal recovery performance
Pin 3	Anode 2	Input terminal for second diode leg; enables dual-channel freewheeling or synchronous rectification pairing

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R06DJF	V_RRM=600V, t_rr=30ns, V_F=1.15V @ 5A - higher voltage rating but higher VF and no dual-die configuration	Single-diode SO-20 package; not pin-compatible; suited for single-channel 600V systems only	Select when 600V blocking is required and dual-anode topology is unnecessary
ON Semi MUR1020CT	V_RRM=200V, t_rr=35ns, V_F=1.0V @ 5A - same recovery speed but higher voltage grade and slightly higher VF	TO-220AC package with isolated tabs; requires separate mounting hardware vs. common-cathode SF1002G	Choose when 200V rating is needed and dual-anode isolation is preferred over common-cathode integration

Compared with STTH10R06DJF and MUR1020CT, SF1002G offers optimized 100V/10A performance with integrated dual-anode common-cathode topology, lower forward drop, and TO-220AB mechanical compatibility - making it ideal for space-constrained dual-output or interleaved converter designs where 100V blocking suffices.

FAQ

What is the maximum junction temperature rating for SF1002G?

The SF1002G has a maximum junction temperature (T_J) rating of +150°C, with operational range from -55°C to +150°C. This rating is specified in the Absolute Maximum Ratings table and confirmed across all electrical and thermal test conditions in the K2104 datasheet revision. Derating curves in Figure 1 define allowable average forward current versus case temperature, ensuring safe operation within this thermal envelope when mounted with appropriate heatsinking.

Is SF1002G pin-compatible with SF1002GH?

Yes, SF1002G and SF1002GH share identical TO-220AB package dimensions, pinout, and thermal-mechanical specifications. The "H" suffix denotes AEC-Q101 qualification - meaning SF1002GH undergoes additional stress testing (HTOL, TC, UHAST) but retains identical electrical parameters, pin assignment, and mounting requirements as SF1002G. No PCB or layout changes are needed when upgrading to the qualified variant.

What is the reverse recovery time measurement condition for SF1002G?

The reverse recovery time (t_rr) of 35ns for SF1002G is measured under the condition: I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A, as stated in the Electrical Specifications table. This standardized test setup ensures consistency across the SF1001G–SF1008G family and aligns with JEDEC JESD24-10 methodology for super fast rectifiers.

Does SF1002G have a common-cathode or common-anode configuration?

SF1002G uses a common-cathode configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes. This is confirmed by the marking diagram, mechanical outline, and dual-die description in the datasheet. The configuration supports parallel freewheeling paths or dual-output rectification without external interconnection.

What is the junction-to-case thermal resistance of SF1002G?

The junction-to-case thermal resistance (R_θJC) of SF1002G is 3.5°C/W, as specified in the Thermal Performance section. This value applies to conduction through the center tab (cathode) to the heatsink interface and is measured under standard JEDEC JESD51-14 conditions. It enables accurate thermal modeling for heatsink selection when operating at full 10A DC current.
