Product details

Overview

FGP30BHE3/73 from Vishay General Semiconductor is a glass-passivated ultrafast plastic rectifier diode in DO-204AC (DO-15) package, rated for 100 V repetitive peak reverse voltage (V_RRM), 3.0 A average forward current (I_F(AV)), and 35 ns reverse recovery time (t_rr). It delivers low forward voltage drop (0.95 V at 3.0 A), high surge capability (125 A I_FSM), and AEC-Q101 qualification for automotive-grade reliability in switching power supplies.

For engineers reviewing the FGP30BHE3/73 datasheet, FGP30BHE3/73 pinout, FGP30BHE3/73 application, or FGP30BHE3/73 equivalent, key selection criteria include ultrafast recovery for high-frequency SMPS freewheeling, thermal robustness up to 175 °C junction temperature, RoHS-compliant matte tin-plated leads, and cavity-free glass-passivated junction construction.

Technical Context

This diode employs a SUPERECTIFIER® structure with cavity-free glass-passivated junction technology to ensure high reliability under thermal cycling and mechanical stress. Its 35 ns reverse recovery time enables efficient operation in 100–500 kHz switching converters without excessive switching losses.

The device supports high forward surge capability (125 A, 8.3 ms half-sine) and maintains low leakage (5.0 μA at 25 °C, 50 μA at 100 °C) across its -65 °C to +175 °C operating junction temperature range. Thermal resistance is 55 °C/W (junction-to-ambient, PCB-mounted) and 20 °C/W (junction-to-lead).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse blocking voltage; defines safe DC/peak AC voltage limit in rectifier/freewheeling paths
I_F(AV)	3.0 A - continuous forward current rating at 25 °C ambient with 0.375" lead length; sets baseline conduction capacity
t_rr	35 ns - ultrafast reverse recovery time measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables high-frequency (>200 kHz) SMPS operation
V_F	0.95 V - forward voltage at 3.0 A; directly determines conduction loss and thermal load in high-current paths
I_R	5.0 μA at 25 °C - low reverse leakage ensures minimal standby power loss and stable voltage hold-off
T_J(max)	+175 °C - maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600 V V_RRM, 3.0 A I_F(AV), 50 ns t_rr, TO-220AC package	Higher voltage rating but slower recovery and larger footprint; suited for 400 V PFC stages	Select when >200 V blocking is required and board space permits TO-220 mounting
ES3D-E3/54	200 V V_RRM, 3.0 A I_F(AV), 35 ns t_rr, same DO-15 package, non-AEC-Q101	Same speed and form factor but lacks automotive qualification; lower cost for commercial-grade designs	Choose for cost-sensitive consumer or industrial applications where AEC-Q101 is not mandated

Compared with STTH3L06S and ES3D-E3/54, the FGP30BHE3/73 uniquely combines 100 V rating, 35 ns recovery, AEC-Q101 qualification, and DO-15 footprint-making it optimal for compact, thermally demanding automotive and industrial SMPS freewheeling where reliability and size are critical.

FAQ

What is the maximum junction temperature rating for the FGP30BHE3/73?

The FGP30BHE3/73 has a maximum junction temperature (T_J(max)) of +175 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet show usable current capacity down to 1.0 A at 125 °C ambient with standard PCB mounting. The FGP30BHE3/73 must be thermally managed to stay within this limit during continuous operation.

Is the FGP30BHE3/73 pin-compatible with other DO-15 ultrafast diodes like the UF4007?

No, the FGP30BHE3/73 is not pin-compatible with UF4007 in functional replacement terms. While both use DO-15 packaging and share anode/cathode polarity marking, the FGP30BHE3/73 is AEC-Q101 qualified, has 35 ns t_rr, and is rated for 100 V V_RRM; UF4007 offers 1000 V V_RRM but 75 ns t_rr. Substitution requires validation of voltage, speed, and qualification requirements. The FGP30BHE3/73 is optimized for high-frequency, automotive-grade use-not general-purpose replacement.

Does the HE3 suffix on FGP30BHE3/73 indicate AEC-Q101 qualification?

Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature. The "H" signifies AEC-Q101 compliance, "E3" indicates RoHS-compliant matte tin plating meeting JESD 201 Class 2 whisker test. This distinguishes FGP30BHE3/73 from base FGP30B-E3 variants, which are commercial-grade only. The FGP30BHE3/73 datasheet confirms AEC-Q101 qualification in the Primary Characteristics table and Mechanical Data section.

What is the thermal resistance from junction to ambient (R_θJA) for the FGP30BHE3/73?

The typical junction-to-ambient thermal resistance (R_θJA) for the FGP30BHE3/73 is 55 °C/W, measured with 0.375" (9.5 mm) lead length mounted on a PCB with 1.1" × 1.1" (30 mm × 30 mm) copper pads. This value assumes standard JEDEC test conditions and is critical for calculating temperature rise under load. The FGP30BHE3/73 also has R_θJL = 20 °C/W (junction-to-lead) when both leads are attached to heatsinks.

Can the FGP30BHE3/73 be used in place of the FGP30CHE3/73 or FGP30DHE3/73?

No-the FGP30BHE3/73 is not interchangeable with FGP30CHE3/73 (150 V V_RRM) or FGP30DHE3/73 (200 V V_RRM) without circuit redesign. All three share identical package, t_rr, I_F(AV), and qualification, but differ in maximum reverse voltage rating. Using FGP30BHE3/73 in a 150 V circuit risks avalanche breakdown. The FGP30BHE3/73 is strictly rated for ≤100 V reverse applications; voltage selection must match system peak reverse stress.
