Product details

Overview

FGP50D-E3/73 from Vishay General Semiconductor is an ultrafast glass-passivated plastic rectifier diode rated for 200 V repetitive peak reverse voltage, 5.0 A average forward current, and 35 ns reverse recovery time, with 0.95 V forward voltage at 5.0 A - used in high-frequency freewheeling and output rectification in automotive DC-DC converters and telecom SMPS.

For engineers reviewing the FGP50D-E3/73 datasheet, FGP50D-E3/73 pinout, FGP50D-E3/73 application, or FGP50D-E3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 135 A surge rating, 175 °C max junction temperature, low leakage (5.0 μA @ 25 °C), and GP20 package compatibility with automated SMT and through-hole assembly.

Technical Context

This device implements a Superectifier® structure with cavity-free glass-passivated junction to ensure high reliability under thermal cycling and humidity stress. Its ultrafast trr of 35 ns enables efficient operation in switching frequencies up to several hundred kHz without excessive switching losses.

The FGP50D-E3/73 delivers low conduction loss (VF = 0.95 V @ 5.0 A) and low leakage (IR = 5.0 μA @ 25 °C, 50 μA @ 100 °C), supporting high-efficiency power conversion in constrained thermal environments. Thermal resistance is 20 °C/W junction-to-lead and 60 °C/W junction-to-ambient on PCB.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH5L06D	600 V V_RRM, 5 A I_F(AV), 50 ns t_rr, TO-220AC package	Higher voltage rating but slower recovery; suited for 400 V PFC stages, not 200 V output rectification	Select when higher reverse voltage margin is required and board space allows TO-220 footprint
ON Semi MUR520E	200 V V_RRM, 5 A I_F(AV), 35 ns t_rr, DO-201AD package, no AEC-Q101 qualification	Same electrical specs but lacks automotive qualification and has higher R_θJA (75 °C/W)	Acceptable for commercial-grade telecom or computing where AEC-Q101 is not mandated

Compared with STTH5L06D and MUR520E, the FGP50D-E3/73 uniquely combines AEC-Q101 qualification, GP20 package thermal performance (R_θJL = 20 °C/W), and 200 V/35 ns operation - making it optimal for space-constrained, thermally demanding automotive and industrial rectification where reliability validation is mandatory.

FAQ

What is the maximum junction temperature rating for the FGP50D-E3/73?

The FGP50D-E3/73 has a maximum junction temperature (T_J(max)) of +175 °C, verified per Vishay's qualification testing. This rating allows sustained operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in the datasheet define safe operating current versus ambient temperature, and thermal design must account for R_θJL = 20 °C/W when leads are attached to heatsinks. The FGP50D-E3/73 maintains full specification compliance up to this limit.

Is the FGP50D-E3/73 qualified to AEC-Q101 standards?

Yes, the FGP50D-E3/73 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 12-Dec-13 (Document Number: 88879). This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, validating suitability for automotive powertrain and chassis applications. The HE3 suffix denotes AEC-Q101 qualification, and FGP50D-E3/73 carries the HE3 variant designation in ordering codes - confirming its qualified status for automotive use. The FGP50D-E3/73 meets all required test conditions and failure criteria per AEC-Q101 Rev D.

What does the "/73" suffix mean in FGP50D-E3/73?

The "/73" suffix in FGP50D-E3/73 indicates ammo pack packaging: 2000 units per pack, with 1.01 g unit weight and GP20 package format. This differs from "/54", which denotes 1400 units per 13" paper tape and reel. Both E3 variants are RoHS-compliant and commercial grade; the HE3 variants (e.g., FGP50DHE3/73) add AEC-Q101 qualification. The FGP50D-E3/73 is fully compatible with standard pick-and-place and manual assembly workflows using the GP20 outline.

How does the FGP50D-E3/73 compare to the FGP50B and FGP50C variants?

The FGP50D-E3/73 shares identical construction, package (GP20), thermal characteristics, and ultrafast recovery (35 ns) with FGP50B and FGP50C, differing only in maximum repetitive peak reverse voltage: FGP50D is rated at 200 V, versus 100 V for FGP50B and 150 V for FGP50C. All three share 5.0 A I_F(AV), 0.95 V V_F, and 5.0 μA I_R. The FGP50D-E3/73 is selected when 200 V blocking is required - such as in 48 V automotive systems or 100–200 VDC intermediate bus applications.

What is the thermal resistance from junction to ambient for the FGP50D-E3/73?

The FGP50D-E3/73 has a typical thermal resistance from junction to ambient (R_θJA) of 60 °C/W when mounted on a PCB per standard JEDEC test conditions. This value assumes 0.375" (9.5 mm) lead length and no external heatsinking. For improved thermal performance, the datasheet specifies R_θJL = 20 °C/W junction-to-lead when both leads are attached to copper heatsinks - a design option that significantly lowers operating temperature. The FGP50D-E3/73 thermal data is measured and published in Document Number 88879.
