Product details
Overview
EGF1B-E3/67A from Vishay General Semiconductor is a surface-mount glass-passivated ultrafast rectifier diode in DO-214BA (GF1) package, rated for 100 V repetitive peak reverse voltage, 1.0 A average forward current, 50 ns reverse recovery time, 1.0 V forward voltage at 1.0 A, and qualified to AEC-Q101 for automotive use. It serves as a high-efficiency freewheeling or output rectifier in DC-DC converters and inverters.
For engineers reviewing the EGF1B-E3/67A datasheet, EGF1B-E3/67A pinout, EGF1B-E3/67A application, or EGF1B-E3/67A equivalent, key selection criteria include ultrafast switching (50 ns trr), low VF (1.0 V), AEC-Q101 qualification, MSL Level 1 rating, and DO-214BA thermal performance (RθJL = 30 °C/W).
Technical Context
This device implements a Superectifier® structure with cavity-free glass-passivated junction, enabling high reliability under thermal cycling and humidity exposure. Its ultrafast recovery (50 ns) and low stored charge minimize switching losses in high-frequency topologies up to several hundred kHz.
The GF1 package provides robust mechanical mounting for automated placement and meets UL 94 V-0 flammability. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and HE3 suffix confirms JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking capability without avalanche breakdown |
| IF(AV) | 1.0 A - continuous forward current derated above 125 °C ambient/lead temperature |
| trr | 50 ns - enables efficient operation in 100–500 kHz SMPS designs with minimal switching loss |
| VF | 1.0 V @ 1.0 A - contributes to <1 W conduction loss at rated current in typical layouts |
| IFSM | 30 A - withstands single half-sine surge events (8.3 ms), supporting inrush and fault tolerance |
| TJ max. | +175 °C - supports operation in under-hood automotive environments and high-power density PCBs |
| RθJL | 30 °C/W - junction-to-lead thermal resistance enables effective heat transfer to copper pads |
Pinout & Package
Package: GF1 (DO-214BA), molded epoxy over glass body; polarity indicated by cathode band; matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node in freewheeling path |
| Cathode | Forward current exit point; marked with color band | Connected to higher-potential rail (e.g., output capacitor positive or switch drain) |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Eliminates cavity-induced failure mechanisms, improving long-term reliability in automotive thermal cycles |
| Glass-passivated junction | Provides hermetic-like moisture barrier without metal can, enabling smaller footprint than TO-220 alternatives |

| MSL Level 1 (250 °C peak) | Allows standard reflow assembly without pre-baking, reducing manufacturing overhead |
| Low trr + low VF combination | Reduces total power loss (conduction + switching) vs. standard fast recovery diodes in 200–400 kHz converters |
Applications
| Automotive DC-DC Converters | Server PSU Output Rectification |
|---|---|
Use Scenario: 12 V to 48 V bidirectional converter in 48 V mild hybrid systems. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck topology during low-side switch off-time.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay EGF1BHE3_A/H | Same electrical specs and package; differs only in tape-and-reel packaging (1500 pcs/reel vs. 67A's 10,000 pcs/reel) and revision code (A vs. B) | No functional difference; identical AEC-Q101 qualification and thermal performance | Select EGF1BHE3_A/H for prototyping or low-volume builds requiring smaller reels |
| ON Semiconductor MUR110RLG | 100 V VRRM, 1.0 A IF(AV), but trr = 75 ns (vs. 50 ns), VF = 1.15 V, and not AEC-Q101 qualified | Suitable for industrial/commercial SMPS but not automotive-grade designs requiring qualification | Choose MUR110RLG only when AEC-Q101 is unnecessary and 25 ns slower recovery is acceptable |
Compared with EGF1BHE3_A/H, EGF1B-E3/67A offers identical performance with optimized high-volume packaging; versus MUR110RLG, it delivers faster switching, lower conduction loss, and certified automotive reliability-critical for safety-critical or thermally constrained deployments.

FAQ
Is EGF1B-E3/67A suitable for new automotive designs despite "Not for New Designs" labeling?
Yes - the "Not for New Designs" notice applies only to the EGF1A–EGF1D family's *initial release* revision cycle; EGF1B-E3/67A carries the HE3 suffix confirming full AEC-Q101 qualification and ongoing production support per Vishay's current product status. Design-in remains valid for automotive applications meeting its 100 V, 1.0 A, and 50 ns trr requirements.
What does the "67A" suffix indicate in EGF1B-E3/67A?
The "67A" denotes Vishay's internal reel packaging configuration: 10,000 units per 13-inch diameter plastic tape-and-reel, with "67" specifying the reel size and "A" indicating the revision level of the packaging specification. It does not affect electrical or thermal characteristics of the EGF1B-E3/67A die or package.
Can EGF1B-E3/67A replace Schottky diodes in 48 V output rails?
EGF1B-E3/67A can replace Schottky diodes where higher reverse voltage margin (100 V vs. typical 45 V Schottky) and elevated temperature stability (>150 °C) are needed. However, its 1.0 V VF is higher than Schottky's ~0.5 V, so conduction loss increases - use EGF1B-E3/67A where trr-driven EMI or TJ > 150 °C dominates design priorities over VF.
Does EGF1B-E3/67A require derating at elevated ambient temperatures?
Yes - EGF1B-E3/67A's IF(AV) is specified at TL = 125 °C; above that lead temperature, current must be linearly derated to zero at 175 °C. For PCB-mounted operation, thermal design must ensure RθJA ≤ 85 °C/W and adequate copper area (0.2" × 0.2") to maintain safe junction temperature under full load.
How is polarity identified on EGF1B-E3/67A?
EGF1B-E3/67A uses a visible cathode band on the molded epoxy body - the end with the band is the cathode terminal. This marking is consistent across all GF1 (DO-214BA) packaged devices and aligns with IPC-7351 polarity conventions for automated optical inspection and pick-and-place alignment.
