Product details

Overview

SF33GHR0G from Taiwan Semiconductor is a 150 V, 3 A super fast recovery rectifier diode in DO-201AD package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 3 A/25°C, and 125 A surge capability - deployed in DC-DC converters and freewheeling paths of automotive switching power supplies.

For engineers reviewing the SF33GHR0G datasheet, SF33GHR0G pinout, SF33GHR0G application, or SF33GHR0G equivalent, key selection criteria include V_RRM = 150 V, I_F = 3 A, t_rr = 35 ns, R_θJL = 10 °C/W, and AEC-Q101 qualification status - critical for high-reliability industrial and automotive power conversion designs.

Technical Context

This super fast rectifier uses a single-die silicon PN junction optimized for low conduction loss and rapid minority-carrier recombination. Its 35 ns reverse recovery time enables efficient operation in 100–500 kHz switching topologies without excessive switching loss or EMI generation.

The device operates across –55°C to +150°C junction temperature range with 10 °C/W junction-to-lead thermal resistance, supporting high-power-density layouts where lead-frame conduction dominates heat dissipation. It is rated for 125 A non-repetitive surge (8.3 ms half-sine), suitable for transient overload conditions in SMPS primary-side rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling clamp circuits
I_F	3 A continuous - average forward current rating at T_L = 75°C; determines heatsink-free power handling up to ~2.85 W conduction loss
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables clean turn-off in high-frequency hard-switched converters
V_F	0.95 V @ 3 A, 25°C - forward voltage drop directly impacts conduction efficiency and thermal rise in 12–48 V output stages
R_θJL	10 °C/W - thermal resistance from junction to lead; allows direct PCB copper pour thermal coupling without dedicated heatsink
I_FSM	125 A @ 8.3 ms - surge rating supports inrush and fault-current robustness in automotive 12 V/24 V systems
Junction temp	–55°C to +150°C - extended temperature range validated per AEC-Q101, enabling under-hood deployment

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	V_RRM = 600 V, t_rr = 35 ns, V_F = 1.15 V @ 3 A - higher voltage rating but higher forward loss	Used in universal-input PFC front-ends; less optimal for 150 V-class outputs due to excess V_RRM margin and efficiency penalty	Select when system requires >300 V blocking or legacy 600 V design reuse; not drop-in for SF33GHR0G footprint or thermal profile
ON Semi MUR3150	V_RRM = 150 V, t_rr = 35 ns, V_F = 0.92 V @ 3 A - identical voltage/speed, slightly lower V_F, no AEC-Q101 claim	Common in industrial SMPS; lacks automotive qualification documentation and whisker test data	Prefer for cost-sensitive non-automotive applications; verify qualification status if used in automotive BOMs

Compared with STTH3L06S and MUR3150, SF33GHR0G uniquely combines 150 V rating, 0.95 V V_F, 35 ns t_rr, and full AEC-Q101 validation - making it the only option qualified for automotive under-hood freewheeling use without derating or requalification.

FAQ

What is the peak repetitive reverse voltage rating of SF33GHR0G?

The SF33GHR0G has a peak repetitive reverse voltage (V_RRM) rating of 150 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2105). It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown, and is critical for selecting appropriate clamping margins in flyback and freewheeling applications. Exceeding 150 V risks irreversible avalanche failure.

Is SF33GHR0G qualified to AEC-Q101 standards?

Yes, SF33GHR0G is AEC-Q101 qualified. The "H" suffix in the ordering code (SF33GHR0G) explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering information table. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST), validating suitability for automotive under-hood applications.

What is the forward voltage drop of SF33GHR0G at rated current?

The forward voltage drop (V_F) of SF33GHR0G is 0.95 V at I_F = 3 A and T_J = 25°C, as specified in the Electrical Specifications table. This value increases with junction temperature and current - e.g., ~1.05 V at 125°C - and directly determines conduction loss and thermal design requirements in the target application.

What package type does SF33GHR0G use, and what are its key mechanical properties?

SF33GHR0G uses the DO-201AD axial-leaded package. Key mechanical properties include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002, JESD201 Class 2 whisker resistance, and a typical weight of 1.10 g. Polarity is indicated by a cathode band on the banded end.

What is the reverse recovery time (t_rr) specification for SF33GHR0G?

The reverse recovery time (t_rr) of SF33GHR0G is 35 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is listed in the Electrical Specifications table and confirms the device's classification as a super fast rectifier - essential for minimizing switching loss and EMI in 100–500 kHz power converters.
