Product details

Overview

GP02-40-M3/54 from Vishay General Semiconductor is a high-voltage glass-passivated junction plastic rectifier diode in DO-41 package, rated for 4000 V repetitive peak reverse voltage (V_RRM), 0.25 A average forward current (I_F(AV)), and 15 A non-repetitive surge current (I_FSM). It serves as a primary rectifier in high-voltage DC power supplies and freewheeling diode in industrial inverters.

For engineers reviewing the GP02-40-M3/54 datasheet, GP02-40-M3/54 pinout, GP02-40-M3/54 application, or GP02-40-M3/54 equivalent, key selection criteria include verified V_RRM = 4000 V, low I_R = 5.0 μA at 25 °C, fast t_rr = 2.0 μs, T_J(max) = 175 °C operation, and DO-41 mechanical compatibility with standard through-hole PCB layouts.

Technical Context

This device implements a Superectifier® structure with cavity-free glass-passivated junction to ensure high reliability under high-voltage stress and thermal cycling. Its design supports stable operation up to 175 °C junction temperature and maintains low leakage (I_R ≤ 5.0 μA at 25 °C) even at rated 4000 V DC blocking voltage.

The GP02-40-M3/54 delivers fast recovery (t_rr = 2.0 μs) and low junction capacitance (C_J = 3.0 pF at 4.0 V, 1 MHz), enabling efficient switching in high-frequency converter topologies while minimizing reverse recovery losses and EMI generation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay GP02-40-E3/54	Same die, identical V_RRM, I_F(AV), t_rr, and DO-41 package; differs only in lead finish (matte tin vs. M3's specified finish)	No functional difference in rectification or surge performance; identical thermal and electrical behavior	Select GP02-40-M3/54 when M3-grade plating compliance (e.g., JESD 201 Class 1A whisker resistance) is required.
ON Semiconductor BYV26E-400	400 V lower V_RRM (3600 V), same I_F(AV) and t_rr; TO-220AC package, not DO-41	Requires PCB layout change and heatsinking; unsuitable for space-constrained DO-41 footprints	Consider only if higher thermal dissipation is needed and board redesign is acceptable.

Compared with GP02-40-E3/54, the GP02-40-M3/54 offers identical core performance with enhanced whisker resistance; compared with BYV26E-400, it provides direct DO-41 drop-in capability but lower thermal mass, making it optimal for compact, high-reliability through-hole HV rectification where layout reuse is critical.

FAQ

What is the maximum junction temperature rating for GP02-40-M3/54?

The GP02-40-M3/54 has a maximum junction temperature (T_J(max)) of +175 °C, confirmed in the Vishay datasheet Document Number 88635. This rating allows reliable operation in high-ambient environments such as enclosed industrial power cabinets or under sustained load conditions. Derating curves show usable I_F(AV) down to ~0.05 A at 150 °C ambient, supporting thermal design flexibility. The GP02-40-M3/54 must be mounted with 0.375" (9.5 mm) lead length for specified thermal resistance.

Is GP02-40-M3/54 suitable for new designs?

No - the Vishay datasheet explicitly states "Not for New Designs" for the GP02-40-M3/54 and the entire GP02 family (Revision: 09-Aug-2022). While fully functional and supported for existing production, Vishay recommends evaluating newer alternatives for greenfield projects. The GP02-40-M3/54 remains available for legacy program continuity, repair, and maintenance where DO-41 footprint and 4000 V rating are mandatory.

What does the 'M3' suffix indicate in GP02-40-M3/54?

The 'M3' suffix in GP02-40-M3/54 specifies a lead finish compliant with JESD 201 Class 1A whisker testing, ensuring long-term reliability under thermal cycling and high-humidity conditions. Unlike the E3 suffix (RoHS-compliant matte tin), M3 denotes an enhanced plating process optimized for mission-critical industrial and medical applications. The GP02-40-M3/54 retains identical electrical specs and DO-41 packaging as other GP02-40 variants.

What is the reverse recovery time (t_rr) of GP02-40-M3/54 and how is it measured?

The GP02-40-M3/54 has a typical reverse recovery time (t_rr) of 2.0 μs, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the Vishay datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss and EMI in high-frequency converters. The GP02-40-M3/54's fast t_rr supports use in flyback and forward topologies operating up to ~200 kHz.

Does GP02-40-M3/54 meet UL 94 flammability requirements?

Yes - the GP02-40-M3/54 uses a molding compound certified to UL 94 V-0 flammability rating, as stated in the Vishay mechanical data section. This qualification ensures self-extinguishing behavior within 10 seconds after flame removal and no dripping of flaming particles, meeting safety standards for Class I, Division 2 hazardous locations and industrial equipment enclosures. The GP02-40-M3/54's V-0 compliance is intrinsic to its DO-41 package construction.
