Product details

Overview

GI250-1-E3/73 from Vishay General Semiconductor is a high-voltage glass-passivated plastic rectifier diode in DO-41 package, rated for 1000 V repetitive peak reverse voltage (V_RRM), 0.25 A average forward current (I_F(AV)), and 15 A non-repetitive surge current (I_FSM). It serves as a primary rectifier in high-voltage AC/DC power supplies and freewheeling diode in DC-DC converters.

For engineers reviewing the GI250-1-E3/73 datasheet, GI250-1-E3/73 pinout, GI250-1-E3/73 application, or GI250-1-E3/73 equivalent, key selection criteria include its 3.5 V forward voltage at 0.25 A, 5.0 μA reverse leakage at 25 °C, 2.0 μs reverse recovery time, DO-41 mechanical outline, and RoHS-compliant matte tin-plated leads.

Technical Context

This device employs a Superectifier® structure with cavity-free glass-passivated junction, enabling stable operation up to 175 °C junction temperature and low leakage under high DC blocking stress. Its thermal resistance (R_θJA) is 130 °C/W at 0.375" lead length on PCB, supporting reliable conduction in compact high-voltage designs.

The GI250-1-E3/73 exhibits fast switching behavior with typical trr of 2.0 μs and low junction capacitance (3.0 pF at 4.0 V, 1 MHz), making it suitable for medium-frequency rectification where reduced switching loss and EMI are critical - unlike standard general-purpose rectifiers with slower recovery and higher C_J.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports rectification in 700 V RMS input circuits without breakdown
I_F(AV)	0.25 A - continuous DC output capability with 0.375" lead length at 75 °C ambient
I_FSM	15 A - withstands single half-sine surge (8.3 ms) during power-up or fault transients
V_F	3.5 V @ 0.25 A - defines conduction loss and thermal dissipation in steady-state operation
I_R	5.0 μA @ 25 °C - ensures minimal standby power loss in high-impedance blocking paths
t_rr	2.0 μs - enables use in 100–500 kHz switching converters with controlled turn-off loss
T_J max.	175 °C - allows operation in thermally constrained industrial or automotive under-hood environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4007G-E3/54	Same DO-41 package; lower V_RRM (1000 V), but higher V_F (1.1 V @ 1 A) and slower t_rr (>30 μs)	Not suitable for >100 kHz switching; limited surge rating (30 A vs. 15 A)	Acceptable only in low-frequency, low-dI/dt linear supplies where fast recovery is not required
GBU4K-E3/54	Bridge configuration (4-diode); higher I_F(AV) (4 A), but larger GBU package and no single-diode flexibility	Requires full-wave bridge layout; unsuitable for discrete freewheeling or half-wave use	Preferred when full-wave rectification is needed and board space permits larger footprint

Compared with 1N4007G-E3/54 and GBU4K-E3/54, the GI250-1-E3/73 delivers faster recovery and lower leakage in a single-diode DO-41 form factor - critical for medium-frequency converters and precision HV hold-off, though it is marked "Not for New Designs" per Vishay documentation.

FAQ

What is the maximum junction temperature rating for GI250-1-E3/73?

The GI250-1-E3/73 has a specified operating junction temperature range of –65 °C to +175 °C. This 175 °C maximum enables reliable operation in high-ambient environments such as enclosed industrial power supplies or near heat-generating components. Derating curves in the Vishay datasheet (Doc. #88625) define safe I_F(AV) limits above 75 °C ambient, based on 0.375" lead length mounting.

Is GI250-1-E3/73 RoHS-compliant and lead-free?

Yes, GI250-1-E3/73 is RoHS-compliant and lead-free. The "E3" suffix explicitly indicates compliance with EU RoHS Directive 2011/65/EU, and the matte tin-plated leads meet JESD 201 Class 1A whisker testing requirements. Vishay confirms this in the ordering information section of document 88625, where "Base P/N-E3" is defined as RoHS-compliant, commercial grade.

What does "Not for New Designs" mean for GI250-1-E3/73?

"Not for New Designs" indicates Vishay no longer recommends GI250-1-E3/73 for newly initiated projects, typically due to newer alternatives with improved performance or packaging. However, the part remains fully manufactured and supported for existing designs requiring continuity. Aetrix Electronics maintains active inventory and supply chain support for GI250-1-E3/73 to ensure BOM stability in legacy systems.

How does the reverse recovery time of GI250-1-E3/73 compare to standard rectifiers?

The GI250-1-E3/73 has a typical reverse recovery time (t_rr) of 2.0 μs under defined test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A). This is significantly faster than general-purpose rectifiers like the 1N4007 (t_rr >30 μs), enabling lower switching losses and reduced EMI in medium-frequency power converters operating up to ~500 kHz.

What is the thermal resistance of GI250-1-E3/73, and how is it measured?

The GI250-1-E3/73 has a typical junction-to-ambient thermal resistance (R_θJA) of 130 °C/W, measured with 0.375" (9.5 mm) lead length on a PCB per JESD 51-2. This value assumes standard FR-4 board mounting without heatsinking. Actual R_θJA will improve with copper pour or thermal vias, and must be validated in the final layout using Vishay's derating curves in document 88625.
