Product details

Overview

RGP10BE-E3/91 from Vishay General Semiconductor is a glass-passivated junction fast-switching plastic rectifier diode in DO-41 package, rated for 100 V repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 150 ns reverse recovery time (t_rr), used as a freewheeling or output rectifier in AC/DC adapters and telecom power supplies.

For engineers reviewing the RGP10BE-E3/91 datasheet, RGP10BE-E3/91 pinout, RGP10BE-E3/91 application, or RGP10BE-E3/91 equivalent, key selection criteria include its 150 ns t_rr, 1.3 V forward voltage at 1.0 A, 5.0 µA reverse leakage at 25 °C, DO-41 mechanical compatibility, and suitability for high-efficiency low-noise switching power conversion.

Technical Context

This device implements a single silicon PN junction with cavity-free glass passivation, enabling stable operation up to 175 °C junction temperature and robust resistance to moisture and thermal cycling. Its Superectifier® structure ensures low stored charge and controlled minority-carrier lifetime for consistent fast recovery behavior.

Designed for unidirectional conduction in line-frequency and high-frequency rectification, it supports surge currents up to 30 A (8.3 ms half-sine) and maintains <5.0 µA reverse leakage at rated V_RRM, making it suitable for applications requiring low standby loss and reliable turn-off in flyback and forward converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum non-repetitive reverse voltage the diode blocks without breakdown
I_F(AV)	1.0 A - continuous DC forward current rating at 55 °C ambient with 9.5 mm lead length
t_rr	150 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables efficient high-frequency rectification
V_F	1.3 V - forward voltage drop at 1.0 A, directly impacting conduction loss and thermal design
I_R	5.0 µA - reverse leakage at 25 °C and rated V_DC, critical for low-power standby performance
T_J(max)	175 °C - maximum allowable junction temperature, supporting operation in compact, thermally constrained layouts
R_θJA	55 °C/W - thermal resistance from junction to ambient (PCB mounted, 9.5 mm leads), defines heatsinking requirements

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast-switching rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4937GP-E3/54	V_RRM = 100 V, t_rr = 200 ns, I_F(AV) = 1.0 A, same DO-41 package	Slower recovery increases switching loss in >100 kHz designs; higher V_F (1.55 V) raises conduction loss	Acceptable for cost-sensitive 50–60 Hz or low-frequency SMPS where 150 ns t_rr is not required
ES1J-E3/54	V_RRM = 600 V, t_rr = 35 ns, I_F(AV) = 1.0 A, SMA package (surface-mount)	Higher voltage rating and faster recovery, but incompatible footprint and thermal profile	Preferred for new SMT designs needing higher V_RRM or lower t_rr; requires PCB redesign

Compared with RGP10BE-E3/91, the 1N4937GP-E3/54 offers identical voltage/current ratings but sacrifices 50 ns in recovery speed and adds 0.25 V forward drop, while the ES1J-E3/54 delivers superior speed and voltage margin at the cost of through-hole compatibility and thermal resistance.

FAQ

What is the maximum junction temperature rating for RGP10BE-E3/91?

The RGP10BE-E3/91 has a maximum junction temperature (T_J(max)) of +175 °C, verified per Vishay Document Number 88700. This rating allows the diode to operate reliably in thermally demanding environments such as enclosed power adapters or proximity to power semiconductors. Derating curves in the RGP10BE-E3/91 datasheet define safe current limits at elevated ambient temperatures, and the 55 °C/W thermal resistance assumes standard 9.5 mm lead length on PCB.

Is RGP10BE-E3/91 RoHS-compliant and lead-free?

Yes, RGP10BE-E3/91 is RoHS-compliant and lead-free, as confirmed by the "E3" suffix in its part number. Per Vishay documentation, the E3 designation indicates compliance with EU RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker testing. The matte tin-plated leads meet solderability standards J-STD-002 and JESD 22-B102, and the molding compound satisfies UL 94 V-0 flammability requirements.

What does the "B" in RGP10BE-E3/91 signify?

The "B" in RGP10BE-E3/91 denotes the 100 V repetitive peak reverse voltage (V_RRM) rating within the RGP10x family. Vishay uses alphabetical suffixes across the series: A = 50 V, B = 100 V, D = 200 V, G = 400 V, J = 600 V, K = 800 V, M = 1000 V. All variants share identical package (DO-41), current rating (1.0 A), and thermal characteristics, differing only in V_RRM and corresponding t_rr values.

Can RGP10BE-E3/91 replace RGP10AE-E3/91 in an existing design?

Yes, RGP10BE-E3/91 can directly replace RGP10AE-E3/91 in most cases, provided the circuit's reverse voltage stress remains ≤100 V. Both share identical DO-41 package, pinout, thermal resistance (55 °C/W), forward voltage (1.3 V), and surge rating (30 A). The only functional difference is V_RRM: 100 V vs. 50 V. If the original design operated with ≥2× safety margin over 25 V RMS, upgrading to RGP10BE-E3/91 adds headroom without layout changes.

What is the reverse recovery time (t_rr) test condition for RGP10BE-E3/91?

The reverse recovery time (t_rr) of 150 ns for RGP10BE-E3/91 is measured under standardized conditions: forward current I_F = 0.5 A, reverse current I_R = 1.0 A, and reverse recovery current I_rr = 0.25 A, per Vishay Document Number 88700. This reflects real-world switching behavior in flyback and forward converters. The value is guaranteed maximum and applies across the full operating temperature range, supporting design validation at both room and elevated temperatures.
