Product details

Overview

GI250-2HE3/73 from Vishay General Semiconductor is a high-voltage glass-passivated plastic rectifier diode in DO-41 package, rated for 2000 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 delivers low leakage (5.0 μA at 25 °C), fast recovery (2.0 μs), and operates up to 175 °C junction temperature - used in high-voltage power supply rectification and freewheeling circuits.

For engineers reviewing the GI250-2HE3/73 datasheet, GI250-2HE3/73 pinout, GI250-2HE3/73 application, or GI250-2HE3/73 equivalent, key selection considerations include its 2000 V blocking capability, DO-41 mechanical compatibility, thermal resistance of 130 °C/W, and suitability for industrial inverters and DC-DC converter snubbers where reliability under high-voltage transients is critical.

Technical Context

This device implements a single-junction, superectifier-structured silicon PN diode with cavity-free glass passivation, enabling stable performance under high-voltage stress and elevated temperature. Its 2.0 μs reverse recovery time and 3.0 pF junction capacitance support moderate-frequency switching in line-frequency and auxiliary power applications.

The DO-41 package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, rated for solder dip at 275 °C for 10 s, and meets UL 94 V-0 flammability. Polarity is marked by a cathode band on the glass body.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	2000 V - supports rectification in 1400 V RMS AC line-derived supplies or 2 kV DC bus systems
I_F(AV)	0.25 A at 75 °C with 0.375" lead length - defines continuous DC output capability in compact linear or flyback secondary-side designs
I_FSM	15 A (8.3 ms half-sine) - withstands inrush and fault currents in unregulated HV supplies without failure
V_F	3.5 V at 0.25 A - contributes ~0.875 W conduction loss at full average current, requiring thermal management in enclosed layouts
I_R	5.0 μA at 25 °C / 2000 V - ensures minimal standby power loss and stable voltage hold-up in high-impedance bias networks
t_rr	2.0 μs - limits switching losses and EMI generation when used as a freewheeling diode in <100 kHz converters
T_J max.	175 °C - enables operation in high-ambient environments such as industrial motor drive cabinets or LED driver housings

Pinout & Package

Package: DO-41 (DO-204AL), axial-leaded, molded epoxy over glass body; cathode indicated by color band; RoHS-compliant (E3 suffix), JESD 201 Class 1A whisker tested.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return path)
Cathode	Forward current exit point; reverse-blocking terminal	Marked by color band; ties to positive rail or energy storage capacitor anode in rectifier configurations

Key Features

Feature	Design Value
Superectifier structure	Enhanced junction ruggedness and long-term stability under repeated high-voltage reverse bias stress
Cavity-free glass passivation	Eliminates moisture ingress paths at junction edge, improving humidity robustness and life expectancy in industrial environments
Low leakage (5.0 μA @ 25 °C)	Reduces standby power dissipation and prevents unintended bias drift in high-impedance sensing or timing circuits
High surge rating (15 A)	Supports reliable operation during cold-start surges or short-circuit recovery without bond-wire fusing
175 °C max junction temperature	Enables use in thermally constrained enclosures without derating below full I_F(AV) at ambient ≤75 °C

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02DJF	200 V V_RRM, 2 A I_F(AV), TO-220AC package, 35 ns t_rr	Lower voltage rating; suited for low-voltage, high-current SMPS outputs - not interchangeable in 2 kV systems	Select only if system V_RRM requirement is ≤200 V and higher average current is needed
1N4007G	1000 V V_RRM, 1 A I_F(AV), DO-41, 30 μs t_rr, higher I_R (50 μA)	Half the blocking voltage; slower recovery increases switching loss in freewheeling roles	Acceptable only in ≤700 V RMS AC inputs with relaxed surge and EMI requirements

Compared with STTH2R02DJF and 1N4007G, GI250-2HE3/73 uniquely balances 2000 V blocking, DO-41 form factor, and sub-μs recovery - making it irreplaceable in space-constrained, high-voltage industrial rectifiers where both voltage margin and thermal footprint matter.

FAQ

What is the maximum junction temperature rating for GI250-2HE3/73?

The GI250-2HE3/73 has a maximum junction temperature (T_J) of +175 °C, verified per Vishay Document Number 88625. This rating allows sustained operation in high-ambient industrial environments when mounted with standard 0.375" lead length and proper PCB thermal relief. Derating curves in the GI250-2HE3/73 datasheet define safe I_F(AV) limits above 75 °C ambient.

Is GI250-2HE3/73 RoHS-compliant and lead-free?

Yes, GI250-2HE3/73 is RoHS-compliant and lead-free. The "E3" suffix confirms compliance with EU RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker testing. Terminal plating is matte tin, solderable per J-STD-002 and JESD 22-B102, and the molding compound meets UL 94 V-0 flammability standards.

What does the "/73" suffix indicate in GI250-2HE3/73?

The "/73" suffix in GI250-2HE3/73 denotes the preferred packaging option: 3000-piece ammo pack. Per Vishay's ordering information table, /73 specifies bulk packaging in an industry-standard ammo box format - distinct from /54 (13" tape-and-reel, 5500 pcs). Both share identical electrical and mechanical specifications.

Can GI250-2HE3/73 be used as a direct replacement for GI250-2HE3/54?

Yes, GI250-2HE3/73 and GI250-2HE3/54 are electrically and mechanically identical; only packaging differs. GI250-2HE3/73 uses ammo pack delivery (3000 pcs), while GI250-2HE3/54 uses 13" tape-and-reel (5500 pcs). No layout, soldering, or circuit changes are required when substituting GI250-2HE3/73 for GI250-2HE3/54 in production or prototyping.

Why is GI250-2HE3/73 marked "Not for New Designs"?

Vishay marks GI250-2HE3/73 "Not for New Designs" (per Revision 06-Oct-2021 datasheet) to signal strategic phase-out - indicating no future revisions or enhanced variants will be developed. However, the part remains fully manufactured, stocked, and supported for existing designs, with guaranteed supply continuity through Aetrix Electronics' lifecycle management program.
