Vishay General Semiconductor - Diodes Division 1N4002GPE-E3/73

Overview

1N4002GPE-E3/73 from Vishay General Semiconductor is a glass-passivated junction plastic rectifier diode rated for 100 V repetitive peak reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current. It features low forward voltage drop (1.1 V at 1.0 A), low leakage current (5.0 μA at 25 °C), and operates from –65 °C to +175 °C - commonly used in AC/DC power supply input rectification and freewheeling paths in consumer-grade inverters and converters.

For engineers reviewing the 1N4002GPE-E3/73 datasheet, 1N4002GPE-E3/73 pinout, 1N4002GPE-E3/73 application, or 1N4002GPE-E3/73 equivalent, key selection criteria include V_RRM = 100 V, I_F(AV) = 1.0 A, thermal resistance R_θJA = 55 °C/W, DO-41 package compatibility, and RoHS-compliant matte tin-plated leads per J-STD-002.

Technical Context

This device implements a single silicon PN junction with cavity-free glass passivation, enabling high reliability in continuous conduction mode rectification. Its Superectifier® structure delivers stable reverse recovery time (t_rr = 2.0 μs) and low junction capacitance (C_J = 8.0 pF at 4.0 V, 1 MHz), supporting efficient operation in 50/60 Hz line-frequency applications.

The DO-41 (DO-204AL) axial package provides mechanical robustness and UL 94 V-0 flammability compliance. With T_J(max) = 175 °C and I₂t rating of 3.7 A²s, it supports short-duration overcurrent events without junction failure under standard mounting conditions.

FAQ

What is the maximum junction temperature rating for the 1N4002GPE-E3/73?

The 1N4002GPE-E3/73 has a maximum operating junction temperature of +175 °C, verified per JEDEC registered specifications. This rating allows reliable operation in high-ambient environments such as enclosed power supplies or thermally constrained enclosures. Derating curves in the Vishay datasheet (Document Number 88504) define allowable forward current versus ambient temperature, with full 1.0 A rating maintained up to 75 °C ambient using standard 0.375" lead length mounting.

Is the 1N4002GPE-E3/73 RoHS-compliant and lead-free?

Yes, the 1N4002GPE-E3/73 is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker test requirements. Full compliance documentation is available via Vishay's material declaration portal referenced in document 99912.

Can the 1N4002GPE-E3/73 be used in place of the 1N4002GP?

Yes, the 1N4002GPE-E3/73 is functionally identical to the 1N4002GP in electrical and thermal performance, differing only in packaging and compliance labeling. Both share identical V_RRM = 100 V, I_F(AV) = 1.0 A, and DO-41 package dimensions. The "E3/73" suffix indicates RoHS-compliant ammo-pack packaging (3000 units), whereas "GP" alone refers to the base product designation without packaging or compliance coding.

What is the reverse recovery time (t_rr) of the 1N4002GPE-E3/73 and how does it affect circuit performance?

The 1N4002GPE-E3/73 has a typical reverse recovery time of 2.0 μs under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is appropriate for 50/60 Hz line-frequency rectification but limits usability in high-frequency switch-mode topologies (>5 kHz), where faster recovery diodes would reduce switching losses and EMI. In standard AC/DC adapters or transformer-based supplies, this t_rr introduces negligible loss or ringing.

Does the 1N4002GPE-E3/73 have UL 94 V-0 flammability certification?

Yes, the 1N4002GPE-E3/73 uses a molding compound certified to UL 94 V-0 flammability rating, as stated in the Vishay datasheet (Document Number 88504). This qualification applies to the DO-41 (DO-204AL) package body and supports end-equipment compliance with safety standards including UL/IEC 62368-1 and IEC 60950-1 for consumer and industrial power supplies.
