Product details

Overview

EGP20B-E3/54 from Vishay General Semiconductor is a glass-passivated ultrafast plastic rectifier diode in DO-15 package, rated for 100 V repetitive peak reverse voltage (VRRM), 2.0 A average forward current (IF(AV)), and 50 ns reverse recovery time (trr). It delivers low forward voltage drop (1.25 V at 2.0 A) and low leakage current (5.0 μA at 25 °C), suited for high-frequency freewheeling in SMPS and DC-DC converters.

For engineers reviewing the EGP20B-E3/54 datasheet, EGP20B-E3/54 pinout, EGP20B-E3/54 application, or EGP20B-E3/54 equivalent, key selection criteria include its 100 V blocking rating, ultrafast 50 ns recovery, DO-15 mechanical compatibility, thermal resistance (RθJA = 40 °C/W), and RoHS-compliant matte tin-plated leads per J-STD-002.

Technical Context

The EGP20B-E3/54 uses a Superectifier® structure with cavity-free glass-passivated junction to ensure high reliability under thermal cycling and humidity stress. Its ultrafast recovery (trr = 50 ns) enables efficient operation in switching frequencies up to several hundred kHz without excessive switching losses.

Designed as a single discrete silicon rectifier, it operates across -65 °C to +150 °C junction temperature range and supports 75 A non-repetitive surge current (IFSM) - critical for handling inrush and transient overloads in power supply front-ends and motor drive freewheel paths.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - maximum repetitive reverse voltage the diode blocks reliably in continuous operation
IF(AV)	2.0 A - average forward current at 55 °C ambient with 0.375" lead length, defining continuous power-handling capability
trr	50 ns - ultrafast reverse recovery time enabling high-efficiency switching in SMPS operating up to ~500 kHz
VF	1.25 V at 2.0 A - low forward voltage drop reducing conduction loss and thermal load in high-current paths
IR	5.0 μA at 25 °C - low reverse leakage ensures minimal standby power loss and stable DC bus hold-up
TJ max.	+150 °C - maximum junction temperature supporting operation in compact, thermally constrained enclosures

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R01AP	100 V VRRM, 2.0 A IF(AV), trr = 35 ns, VF = 1.15 V, TO-220AC package	Larger TO-220 footprint; higher thermal mass but requires PCB real estate and mounting hardware	Select when higher surge current (100 A IFSM) and lower VF are prioritized over board space
ES2D-E3/54	200 V VRRM, 2.0 A IF(AV), trr = 35 ns, VF = 1.15 V, same DO-15 package	Higher blocking voltage; not suitable for 100 V-rated circuits without derating review	Choose only if system transients exceed 100 V or future-proofing for 200 V variants is required

Compared with STTH2R01AP and ES2D-E3/54, the EGP20B-E3/54 offers optimal balance of DO-15 footprint compatibility, 100 V rating margin, and proven reliability in cost-sensitive consumer and telecom power supplies - without requiring layout changes or thermal redesign.

FAQ

What is the maximum junction temperature rating for the EGP20B-E3/54?

The EGP20B-E3/54 has a maximum junction temperature (TJ max.) of +150 °C, allowing reliable operation in thermally demanding environments such as enclosed power supplies or industrial control units. This rating is validated per JEDEC standards and supports continuous operation at full IF(AV) when thermal design meets RθJA ≤ 40 °C/W. The EGP20B-E3/54 must be mounted with appropriate copper pour and airflow to sustain this limit.

Is the EGP20B-E3/54 RoHS-compliant and lead-free?

Yes, the EGP20B-E3/54 is RoHS-compliant and features matte tin-plated leads that meet J-STD-002 solderability requirements. The "E3" suffix confirms compliance with JEDEC JESD201 Class 1A whisker testing. The EGP20B-E3/54 contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and conforms to EU Directive 2011/65/EU and China RoHS II.

What does the "/54" suffix indicate in EGP20B-E3/54?

The "/54" suffix in EGP20B-E3/54 specifies the packaging configuration: 4000 units per 13-inch diameter paper tape and reel. This format is optimized for automated SMT placement equipment. The EGP20B-E3/54 is not supplied in bulk or ammo pack - those use alternate suffixes like "/73". Traceability and moisture sensitivity level (MSL) are documented per Vishay's packaging specification 88583.

Can the EGP20B-E3/54 replace standard FR107 or UF4007 diodes?

The EGP20B-E3/54 can replace FR107 (1000 V, 1 A) or UF4007 (1000 V, 1 A) only in applications where voltage rating is reduced to ≤100 V and current demand is ≤2.0 A. Unlike those parts, the EGP20B-E3/54 offers lower VF (1.25 V vs. ~1.7 V) and faster trr (50 ns vs. 75 ns), but its 100 V VRRM makes it unsuitable for 600–1000 V applications. Always verify circuit stress margins before substituting the EGP20B-E3/54.

Why is the EGP20B-E3/54 marked "Not for New Designs"?

Vishay designates the EGP20B-E3/54 as "Not for New Designs" because newer ultrafast rectifiers with improved VF, trr, and thermal performance (e.g., VS-EGP20BHM3) have superseded it. However, the EGP20B-E3/54 remains fully supported for existing production, repair, and legacy BOM continuity. Aetrix Electronics maintains active inventory and long-term sourcing agreements to ensure uninterrupted supply of the EGP20B-E3/54.
