Product details
Overview
1N3611GPHE3/73 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 (VF) at 1.0 A. It delivers low leakage (IR ≤ 1.0 μA at 25 °C), fast recovery (trr = 2.0 μs), and operates up to 175 °C junction temperature - used in AC/DC power supply input rectification and freewheeling paths.
For engineers reviewing the 1N3611GPHE3/73 datasheet, 1N3611GPHE3/73 pinout, 1N3611GPHE3/73 application, or 1N3611GPHE3/73 equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 55 °C/W), surge capability (IFSM = 30 A), and DO-41 mechanical compatibility with legacy through-hole power designs.
Technical Context
This device implements a single silicon PN junction with cavity-free glass passivation, enabling high reliability in industrial and commercial power conversion. Its Superectifier® structure ensures stable reverse characteristics and low IR across temperature, supported by JEDEC-registered DO-41 (DO-204AL) packaging and matte tin-plated leads compliant with J-STD-002 solderability.
The 1N3611GPHE3/73 operates under standard rectifier bias conditions: unidirectional conduction with cathode band marking, 8.3 ms half-sine surge rating, and thermal performance validated at 0.375" lead length per JESD 22-B106. Junction capacitance is 8.0 pF at 4.0 V / 1 MHz, confirming suitability for moderate-frequency switching applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4001GP-E3/73 | VRRM = 50 V (vs. 200 V); identical DO-41 package and IF(AV) = 1.0 A | Not suitable for 120 VAC input rectification due to lower blocking voltage | Select only where circuit reverse voltage remains ≤50 V |
| 1N5401-E3/54 | IF(AV) = 3.0 A; VRRM = 50 V; larger DO-204AL package variant (DO-27) | Higher current capacity but incompatible pin spacing and lower voltage rating | Use when higher average current is required and board layout accommodates DO-27 footprint |
Compared with 1N4001GP-E3/73 and 1N5401-E3/54, the 1N3611GPHE3/73 provides optimal balance of 200 V blocking, 1.0 A rating, and DO-41 compatibility for legacy 120 VAC-fed power supplies - neither alternative matches its VRRM/IF(AV) combination in the same package.

FAQ
What is the maximum junction temperature rating for the 1N3611GPHE3/73?
The 1N3611GPHE3/73 has a maximum junction temperature (TJ max.) of +175 °C, allowing reliable operation in high-ambient environments such as enclosed industrial power supplies or near heat-generating components. This rating is validated per JEDEC standards and supports derating curves up to 75 °C ambient with 0.375" lead length. Thermal design must account for RθJA = 55 °C/W to avoid exceeding TJ max. during sustained 1.0 A conduction.
Is the 1N3611GPHE3/73 RoHS-compliant and lead-free?
Yes, the 1N3611GPHE3/73 is RoHS-compliant and lead-free, indicated by the "E3" suffix in its part number. It meets JESD 201 Class 1A whisker test requirements and uses matte tin-plated leads solderable per J-STD-002. The molding compound complies with UL 94 V-0 flammability rating, and all materials conform to Vishay's material categorization standard documented at www.vishay.com/doc?99912.
What does the "HE3/73" suffix mean in 1N3611GPHE3/73?
The "HE3/73" suffix identifies the packaging and compliance version: "HE3" denotes the RoHS-compliant, high-reliability variant with cavity-free glass passivation, while "/73" specifies ammo pack packaging containing 3000 units. This differs from "/54", which indicates 13" paper tape and reel (5500 units). Both share identical electrical and thermal specifications per Document Number 88502.
Can the 1N3611GPHE3/73 replace a standard 1N4001 in a 120 VAC power supply?
No - while both are DO-41 rectifiers rated for 1.0 A average current, the 1N4001 has only 50 V VRRM and would fail catastrophically in 120 VAC full-wave rectification (peak voltage ≈ 170 V). The 1N3611GPHE3/73's 200 V VRRM provides necessary margin, making it a valid upgrade for 120 VAC inputs where 1N4001 is insufficient. Always verify reverse voltage stress in final design.
What is the reverse recovery time (trr) of the 1N3611GPHE3/73 and why does it matter?
The 1N3611GPHE3/73 has a typical reverse recovery time (trr) of 2.0 μs measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter determines how quickly the diode ceases conduction after reverse bias is applied - critical in freewheeling and switching applications. A shorter trr reduces switching losses and voltage spikes, improving efficiency and EMI performance in inverter and converter topologies.
