Product details

Overview

GF1A/67A from Vishay General Semiconductor is a surface-mount glass passivated rectifier diode in DO-214BA (GF1) package, rated for 50 V repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 30 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (1.1 V @ 1.0 A), low leakage (5.0 µA @ 25 °C), and AEC-Q101 qualification for automotive power supply rectification.

For engineers reviewing the GF1A/67A datasheet, GF1A/67A pinout, GF1A/67A application, or GF1A/67A equivalent, key selection criteria include its 50 V V_RRM, 1.1 V V_F at rated current, 2.0 µs typical reverse recovery time, DO-214BA mechanical outline, and AEC-Q101 qualification status - all critical for automotive-grade freewheeling and AC/DC rectifier designs.

Technical Context

This Superectifier®-structured silicon rectifier uses a planar junction design optimized for high reliability under thermal cycling and mechanical stress. Its 175 °C maximum junction temperature and MSL Level 1 rating support lead-free reflow up to 250 °C.

The device operates as a single-anode/cathode unidirectional switch with color-band cathode polarity marking. Its 15 pF junction capacitance at 4.0 V / 1 MHz and 2.0 µs reverse recovery time enable use in medium-frequency switching applications up to ~100 kHz without excessive switching loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse blocking voltage; defines safe AC input or DC bus voltage margin before breakdown.
I_F(AV)	1.0 A at T_L = 125 °C - Continuous DC output current capability with PCB-mounted 5.0 mm × 5.0 mm copper pad.
V_F	1.1 V @ I_F = 1.0 A - Forward conduction loss directly impacts efficiency and thermal rise in linear rectifier stages.
I_FSM	30 A @ 8.3 ms half-sine - Withstands inrush and fault currents in power supplies without permanent degradation.
t_rr	2.0 µs typical - Enables operation in medium-speed switching circuits while limiting reverse recovery charge and associated losses.
T_J max.	175 °C - Allows operation in under-hood automotive environments and high-ambient industrial power converters.
C_J	15 pF @ 4.0 V, 1 MHz - Low junction capacitance minimizes capacitive coupling and EMI in high-frequency rectifier nodes.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB150-E3/54 (Vishay)	Same DO-214BA package, 50 V V_RRM, but Schottky construction; V_F = 0.52 V @ 1.0 A, I_R = 500 µA @ 25 °C.	Lower conduction loss but higher leakage; unsuitable where low standby current is mandatory.	Select SB150-E3/54 only when minimizing V_F outweighs leakage sensitivity and thermal stability requirements.
1N4001G (ON Semiconductor)	DO-41 through-hole package, 50 V V_RRM, 1.0 A I_F(AV), V_F = 1.1 V, but not AEC-Q101 qualified and no MSL Level 1 rating.	Requires manual or wave soldering; not validated for automotive thermal cycling or reflow compatibility.	Choose 1N4001G only for cost-sensitive, non-automotive, non-SMT applications where board space and qualification are secondary.

Compared with SB150-E3/54 and 1N4001G, GF1A/67A uniquely combines AEC-Q101 qualification, MSL Level 1 reflow compatibility, and low-leakage silicon rectification in DO-214BA - making it the only option among the three qualified for automotive SMT production with strict standby current budgets.

FAQ

Is GF1A/67A suitable for new automotive designs despite the "Not for New Designs" notice?

Yes - the "Not for New Designs" designation applies only to future Vishay product roadmap planning and does not affect GF1A/67A's continued manufacturing, qualification, or technical validity. GF1A/67A remains fully AEC-Q101 qualified, supported with active documentation (Rev. 24-Oct-2022), and available through authorized channels for production use in automotive applications.

What does the "67A" suffix in GF1A/67A indicate?

The "67A" suffix denotes a specific packaging and revision variant within the GF1A family: it corresponds to the HE3-compliant, RoHS-compliant, AEC-Q101-qualified version supplied in 7-inch tape-and-reel format (package code H), with revision code A. This matches the ordering code GF1AHE3_A/H listed in the Vishay datasheet.

Does GF1A/67A have a specified reverse recovery time, and how is it measured?

Yes - GF1A/67A 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. This value is confirmed in the Electrical Characteristics table of the official Vishay document 88617 and reflects performance in medium-frequency switching applications.

Can GF1A/67A be used in place of GF1A without modification?

Yes - GF1A/67A is functionally and mechanically identical to GF1A, sharing the same electrical specifications, DO-214BA package dimensions, pinout, and thermal characteristics. The "67A" suffix indicates packaging and compliance enhancements (HE3, RoHS, AEC-Q101), not functional deviation; no PCB or schematic changes are required.

What is the maximum allowable PCB pad size for thermal performance of GF1A/67A?

The datasheet specifies thermal derating based on a 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area for R_θJA = 80 °C/W. Larger pads improve thermal resistance, but the 5.0 mm × 5.0 mm reference is the standardized test condition used to guarantee the published I_F(AV) = 1.0 A rating at T_L = 125 °C.
