Product details
Overview
1N3611GP-E3/73 from Vishay General Semiconductor is a glass passivated junction plastic rectifier diode in DO-41 package, rated for 200 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 1.0 V forward voltage drop at 1.0 A. It delivers low leakage current (IR ≤ 1.0 μA at 25 °C), 2.0 μs typical reverse recovery time (trr), and operates from –65 °C to +175 °C - suited for freewheeling and general-purpose AC/DC rectification in industrial power supplies.
For engineers reviewing the 1N3611GP-E3/73 datasheet, 1N3611GP-E3/73 pinout, 1N3611GP-E3/73 application, or 1N3611GP-E3/73 equivalent, key selection criteria include its 200 V VRRM rating, DO-41 mechanical compatibility, 30 A non-repetitive surge capability (IFSM), thermal resistance (RθJL = 25 °C/W), and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
This Superectifier®-structured diode uses a cavity-free glass-passivated junction to enhance reliability under thermal cycling and humidity stress. Its fast 2.0 μs reverse recovery time and low 8.0 pF junction capacitance support efficient switching in line-frequency rectifiers and freewheeling paths where minimal stored charge and low capacitive loading are critical.
The device is optimized for operation at ambient temperatures up to 75 °C with 1.0 A average forward current (derated above that point), and features a maximum junction temperature of 175 °C. Its 25 °C/W junction-to-lead thermal resistance enables effective heat dissipation through PCB-mounted leads with 0.375" (9.5 mm) length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe AC input voltage headroom in bridge or half-wave rectifiers |
| IF(AV) | 1.0 A at 75 °C ambient - continuous DC output current capability with standard lead mounting |
| VF | 1.0 V at 1.0 A - low conduction loss enabling higher efficiency in low-voltage secondary-side rectification |
| trr | 2.0 μs - fast recovery minimizes switching losses and EMI in freewheeling and flyback snubber applications |
| IR | 1.0 μA at 25 °C - ultra-low leakage preserves hold-up energy in capacitor-input filters |
| TJ max. | +175 °C - extended junction temperature rating supports high-ambient industrial and automotive under-hood designs |
| RθJL | 25 °C/W - low junction-to-lead thermal resistance allows direct heat transfer to PCB copper via leads |
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 |
|---|---|---|---|
| 1N4001GP-E3/73 | VRRM = 50 V (vs. 200 V); otherwise identical DO-41 package, VF ≈ 1.1 V, trr ≈ 30 μs | Not suitable for 100–240 VAC inputs; limited to low-voltage DC-DC or signal-level rectification | Select only if reverse voltage requirement is ≤50 V and slower recovery is acceptable |
| 1N5401G | IF(AV) = 3.0 A; VRRM = 50 V; DO-201AD package; VF ≈ 1.2 V; trr > 2 μs | Higher current capacity but lower voltage rating and larger footprint; not DO-41 compatible | Choose when ≥2 A average current is required and board space allows larger case |
Compared with 1N3611GP-E3/73, the 1N4001GP-E3/73 offers lower cost but insufficient reverse voltage for universal-input power supplies, while the 1N5401G provides higher current but requires layout change and sacrifices voltage rating - making 1N3611GP-E3/73 optimal for 200 V, 1 A, space-constrained rectification.

FAQ
What is the maximum junction temperature rating for the 1N3611GP-E3/73?
The 1N3611GP-E3/73 has a maximum operating junction temperature of +175 °C. This rating allows reliable operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive modules. The device maintains specified electrical performance up to this limit, provided thermal design accounts for its 25 °C/W junction-to-lead resistance and proper PCB copper area is used for heat sinking.
Is the 1N3611GP-E3/73 RoHS-compliant and lead-free?
Yes, the 1N3611GP-E3/73 is RoHS-compliant and lead-free. The "E3" suffix indicates compliance with EU RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker testing. Its matte tin-plated leads meet J-STD-002 solderability requirements and are compatible with standard reflow and wave soldering processes.
What does the "/73" suffix mean in 1N3611GP-E3/73?
The "/73" suffix in 1N3611GP-E3/73 denotes the packaging configuration: 3000-piece ammo pack. This differs from "/54", which indicates 5500-piece 13-inch paper tape and reel. Both share identical electrical and mechanical specifications; the suffix solely identifies the delivery format for logistics and assembly line feeding.
Can the 1N3611GP-E3/73 be used as a direct replacement for the 1N4001 in a 120 VAC power supply?
No - the 1N3611GP-E3/73 is not a direct replacement for the 1N4001 in a 120 VAC power supply. While both are DO-41 rectifiers, the 1N4001 has only 50 V VRRM, insufficient for 120 VAC (peak ≈ 170 V). The 1N3611GP-E3/73's 200 V VRRM makes it suitable, but its faster 2.0 μs trr may alter EMI behavior versus the 1N4001's ~30 μs trr; verify system noise and snubber requirements before substitution.
Why is the 1N3611GP-E3/73 marked "Not for New Designs"?
The "Not for New Designs" status reflects Vishay's product lifecycle policy: the 1N3611GP-E3/73 remains fully available and supported for existing production, but new designs are encouraged to consider newer alternatives like the VS-1N3611GP-M3/73 or automotive-grade equivalents. This designation does not affect reliability, specification compliance, or supply continuity for current programs.
