Product details

Overview

FGP30D-E3/73 from Vishay General Semiconductor is a glass-passivated ultrafast plastic rectifier diode in DO-204AC (DO-15) package, rated for 200 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 operates up to 175 °C junction temperature-ideal for high-frequency freewheeling in automotive DC-DC converters.

For engineers reviewing the FGP30D-E3/73 datasheet, FGP30D-E3/73 pinout, FGP30D-E3/73 application, or FGP30D-E3/73 equivalent, key selection criteria include its AEC-Q101 qualification, ultrafast switching performance, thermal robustness in constrained PCB layouts, and compatibility with automated placement and lead-free reflow processes per J-STD-002.

Technical Context

This device employs a Superectifier® structure with cavity-free glass-passivated junction, enabling stable operation under high dv/dt and thermal stress. Its 35 ns t_rr and 70 pF junction capacitance support efficient high-frequency rectification in SMPS topologies above 100 kHz.

The DO-204AC package features matte tin-plated leads compliant with JESD 22-B102 solderability and JESD 201 Class 1A whisker testing. With R_θJA = 55 °C/W and R_θJL = 20 °C/W, it sustains continuous conduction in ambient temperatures up to 125 °C when mounted on standard PCB copper pads.

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, 35 ns t_rr, 1.15 V V_F @ 3 A, DO-204AL (DO-41) package	Higher voltage rating suits 48 V industrial systems; higher V_F increases conduction loss by ~0.6 W	Select when system requires >200 V blocking with same speed; verify PCB pad compatibility with DO-41 footprint
ON Semi MUR320	200 V V_RRM, 35 ns t_rr, 0.92 V V_F @ 3 A, DO-204AL (DO-41), non-AEC-Q101	Lower V_F improves efficiency marginally; lacks automotive qualification and glass passivation	Prefer for cost-sensitive consumer power supplies where AEC-Q101 and humidity reliability are not required

Compared with STTH3L06S and MUR320, the FGP30D-E3/73 uniquely combines AEC-Q101 qualification, glass-passivated junction integrity, and DO-204AC mechanical robustness-making it the only choice for automotive under-hood rectification where long-term reliability under thermal cycling and humidity is mandatory.

FAQ

What is the maximum junction temperature rating for the FGP30D-E3/73?

The FGP30D-E3/73 has a maximum junction temperature (T_J(max)) of +175 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in engine compartment environments where ambient temperatures reach 125 °C, provided thermal resistance to ambient (R_θJA = 55 °C/W) is managed via adequate PCB copper area. The FGP30D-E3/73 maintains parameter stability across this full range without parameter shift or premature failure.

Is the FGP30D-E3/73 RoHS-compliant and halogen-free?

Yes, the FGP30D-E3/73 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The molding compound meets UL 94 V-0 flammability rating, and matte tin-plated leads satisfy J-STD-002 solderability requirements. No brominated flame retardants or chlorine-based additives are used in the FGP30D-E3/73 construction.

How does the FGP30D-E3/73 differ from the FGP30B and FGP30C variants?

The FGP30D-E3/73 differs from FGP30B-E3/73 and FGP30C-E3/73 solely in its maximum repetitive peak reverse voltage (V_RRM): 200 V versus 100 V and 150 V respectively. All three share identical package (DO-204AC), forward characteristics (0.95 V V_F, 3.0 A I_F(AV)), reverse recovery time (35 ns), and AEC-Q101 qualification. The FGP30D-E3/73 is selected when system-level transients exceed 150 V.

What packaging format does FGP30D-E3/73 use, and what is the base quantity?

The FGP30D-E3/73 is supplied in ammo pack packaging (package code "73"), with a base quantity of 2000 units per pack. This format supports manual and semi-automated insertion in low-to-medium volume production. Unlike tape-and-reel variants (e.g., FGP30D-E3/54), the ammo pack eliminates carrier tape waste and simplifies kitting for engineering validation and pilot builds using the FGP30D-E3/73.

Can the FGP30D-E3/73 replace standard fast recovery diodes in existing designs?

Yes-the FGP30D-E3/73 can directly replace standard fast recovery diodes with matching V_RRM and I_F(AV), provided layout accommodates DO-204AC (DO-15) dimensions and thermal constraints are re-evaluated. Its 35 ns t_rr and 0.95 V V_F typically reduce switching and conduction losses, but designers must verify that reduced reverse recovery charge does not induce unintended gate oscillation in adjacent MOSFETs when retrofitting the FGP30D-E3/73.
