Product details
Overview
GI250-4HE3/73 from Vishay General Semiconductor is a high-voltage glass-passivated plastic rectifier diode in DO-41 package, rated for 4000 V repetitive peak reverse voltage (VRRM), 0.25 A average forward current (IF(AV)), and 15 A non-repetitive surge current (IFSM). It delivers low leakage (5.0 μA at 25 °C), fast recovery (2.0 μs trr), and operates up to 175 °C junction temperature - used as a freewheeling or output rectifier in high-voltage DC power supplies.
For engineers reviewing the GI250-4HE3/73 datasheet, GI250-4HE3/73 pinout, GI250-4HE3/73 application, or GI250-4HE3/73 equivalent, key selection criteria include verified VRRM = 4000 V, VF = 3.5 V @ 0.25 A, IR ≤ 5.0 μA, trr = 2.0 μs, and DO-41 mechanical compatibility with legacy high-voltage rectifier layouts.
Technical Context
This device implements a single-junction, superectifier®-structured silicon PN rectifier with cavity-free glass passivation, enabling stable operation under high-voltage stress and thermal cycling. Its 2.0 μs reverse recovery time and 3.0 pF junction capacitance support moderate-frequency switching in line-frequency and resonant converter topologies.
The DO-41 package provides robust mechanical mounting and thermal dissipation via axial leads, with matte tin-plated terminals compliant to J-STD-002 and JESD 22-B102 solderability standards. Thermal resistance RθJA is 130 °C/W at 0.375" lead length on PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 4000 V - supports DC blocking in 2800 V RMS input stages (e.g., 3-phase rectification with safety margin) |
| IF(AV) | 0.25 A - continuous conduction capability at 75 °C ambient with 0.375" lead length |
| IFSM | 15 A - withstands single half-sine surge events (8.3 ms) without failure |
| VF | 3.5 V @ 0.25 A - forward drop determines conduction loss and thermal load in rectifier branch |
| trr | 2.0 μs - enables use in <100 kHz switching applications with controlled turn-off loss |
| IR | 5.0 μA @ 25 °C - ensures minimal leakage in high-impedance hold-up or sensing circuits |
| TJ max. | 175 °C - allows operation in sealed enclosures or high-ambient industrial 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 |
|---|---|---|---|
| STTH2R04DJF | 400 V VRRM, TO-220AC package, VF = 1.75 V @ 2 A, trr = 35 ns | Lower voltage rating; suited for medium-voltage, higher-current, faster-switching designs | Select when system requires <500 V blocking and sub-50 ns recovery - not interchangeable for 4 kV use. |
| 1N4007G | 1000 V VRRM, DO-41, IF(AV) = 1.0 A, VF = 1.1 V @ 1 A, trr ≈ 30 μs | Higher current, lower voltage, slower recovery - standard general-purpose rectifier | Acceptable only if design operates ≤1000 V and tolerates higher trr-induced losses. |
Compared with STTH2R04DJF and 1N4007G, GI250-4HE3/73 uniquely satisfies 4000 V blocking with DO-41 form factor and sub-3 μs recovery - critical where space-constrained legacy layouts demand high-voltage resilience without redesign.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for GI250-4HE3/73?
The GI250-4HE3/73 has a VRRM rating of 4000 V, confirmed in the Vishay datasheet (Document Number: 88625, Revision: 06-Oct-2021). This value defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown, making it suitable for rectification in systems with up to ~2800 V RMS input. The GI250-4HE3/73 maintains this rating across its full operating temperature range.
Is GI250-4HE3/73 RoHS-compliant and lead-free?
Yes, GI250-4HE3/73 is RoHS-compliant and lead-free. The "E3" suffix indicates compliance with EU RoHS Directive 2011/65/EU, and the part meets JESD 201 Class 1A whisker test requirements. Terminal plating is matte tin, and the molding compound is UL 94 V-0 rated - all verified in Vishay's official documentation for GI250-4HE3/73.
What is the reverse recovery time (trr) of GI250-4HE3/73 and how is it measured?
The GI250-4HE3/73 has a typical reverse recovery time (trr) of 2.0 μs, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state, directly impacting switching loss and EMI in high-frequency rectifier applications. The value is specified in the Electrical Characteristics table of the GI250-4HE3/73 datasheet.
Can GI250-4HE3/73 be used in surface-mount designs?
No, GI250-4HE3/73 is not suitable for surface-mount designs. It uses the axial-leaded DO-41 (DO-204AL) package, which requires through-hole mounting with 0.375" (9.5 mm) lead length for thermal derating compliance. No SMD variant of GI250-4HE3/73 exists in Vishay's documentation, and substitution with SMD equivalents would require layout revision and validation of voltage, current, and thermal performance.
What does "Not for New Designs" mean for GI250-4HE3/73?
"Not for New Designs" indicates that Vishay no longer recommends GI250-4HE3/73 for newly initiated projects, though active manufacturing and supply continue for existing designs. Customers should evaluate long-term availability and consider migration paths. GI250-4HE3/73 remains fully supported with datasheets, testing, and Aetrix supply chain continuity - but new designs should consult Vishay for qualified replacements.
