Product details
Overview
GI501-E3/73 from Vishay General Semiconductor is a general-purpose plastic rectifier diode in DO-201AD package, rated for 100 V repetitive peak reverse voltage (VRRM), 3.0 A average forward current (IF(AV)), and 100 A non-repetitive surge current (IFSM). It exhibits low forward voltage drop (1.1 V at 9.4 A, TJ = 25 °C), low leakage (5.0 μA at 25 °C), and fast recovery (2.0 μs trr), suited for AC/DC power supply rectification.
For engineers reviewing the GI501-E3/73 datasheet, GI501-E3/73 pinout, GI501-E3/73 application, or GI501-E3/73 equivalent, key selection considerations include its 100 V VRRM rating, DO-201AD through-hole package with cathode band polarity marking, thermal resistance of 20 °C/W (junction-to-ambient), and suitability for freewheeling and converter output stages where moderate surge robustness and low IR are required.
Technical Context
This single-diode rectifier operates as an uncontrolled, silicon PN junction device optimized for line-frequency and medium-frequency switching applications up to several kHz. Its 2.0 μs reverse recovery time and 28 pF junction capacitance support efficient operation in flyback and boost converters without excessive switching loss or EMI generation.
The device uses a molded epoxy DO-201AD case rated UL 94 V-0, with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. It is not AEC-Q101 qualified and is specified for commercial-grade operation across –50 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in rectifier bridge or freewheeling position |
| IF(AV) | 3.0 A - average forward current at 95 °C ambient with 0.375" lead length; determines continuous power handling in linearly derated thermal design |
| IFSM | 100 A - peak non-repetitive surge current (8.3 ms half-sine); supports inrush current tolerance in transformer-coupled supplies |
| VF | 1.1 V @ 9.4 A, 25 °C - forward conduction loss at rated current; directly impacts conduction efficiency and thermal rise |
| IR | 5.0 μA @ 100 V, 25 °C - DC reverse leakage; critical for low-power standby circuits and high-impedance bias networks |
| trr | 2.0 μs - reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; limits usable switching frequency and reduces commutation loss |
| RθJA | 20 °C/W - junction-to-ambient thermal resistance on PCB with 20 mm × 20 mm copper heatsink; enables thermal modeling for board-level layout |
Pinout & Package
DO-201AD package: axial-leaded, cylindrical epoxy-molded body with cathode identified by color band; leads are matte tin-plated, solderable per J-STD-002, and meet JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to AC input or switch node; must withstand full surge current and forward voltage drop |
| Cathode | Forward current exit node / reverse blocking terminal | Marked by color band; ties to output rail or ground return; reverse voltage appears across this terminal during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 1.1 V at 9.4 A ensures <1.2 W conduction loss at full load, reducing heatsink requirements in compact power supplies |
| Low leakage current | 5.0 μA max at 25 °C enables stable DC bias in high-impedance feedback networks and low-quiescent circuits |
| High surge capability | 100 A IFSM supports reliable operation during cold-start surges in offline SMPS and motor drive snubbers |
| Fast reverse recovery | 2.0 μs trr minimizes tail current and associated switching losses in 20–100 kHz converters |
| RoHS-compliant construction | E3 suffix confirms compliance with JEDEC JESD201 Class 1A whisker testing and RoHS Directive 2011/65/EU |
Applications
| AC/DC Power Supply Input Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Full-wave bridge rectification of 50/60 Hz mains input in offline power supplies delivering 10–30 W. IC Role / Device Role / Timing Role: Uncontrolled rectifier conducting during positive half-cycles; blocks reverse voltage during negative half-cycles. Use Value: 100 V VRRM safely accommodates 1.4× RMS input (e.g., 70 V RMS) with margin; 3.0 A IF(AV) supports typical 24 V/1.25 A output designs. | Use Scenario: Output rectification in 60–100 kHz flyback or forward converters powering industrial sensors and PLC I/O modules. IC Role / Device Role / Timing Role: Freewheeling path for transformer secondary current during MOSFET off-time; recovers before next switching cycle. Use Value: 2.0 μs trr prevents cross-conduction loss; 100 A IFSM handles reflected primary-side surge energy without failure. |
| Inverter DC Bus Clamping | Inductive Load Snubber Diode |
Use Scenario: Clamp diode across IGBT collector-emitter in 3-phase motor inverters to suppress inductive kickback during turn-off. IC Role / Device Role / Timing Role: Passive voltage clamp limiting dv/dt stress on switching devices during transient overvoltage events. Use Value: 100 V rating matches common 48 V or 60 V DC bus systems; 100 A IFSM absorbs short-duration energy spikes without thermal runaway. | Use Scenario: Protection diode across relay coils or solenoid drivers in automotive body control modules and HVAC actuators. IC Role / Device Role / Timing Role: Provides low-impedance path for stored inductive energy dissipation when driver switches off. Use Value: Low VF (1.1 V) minimizes clamping voltage overshoot; DO-201AD mechanical robustness withstands repeated mechanical shock in vehicle environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5401G | Same DO-201AD package, 100 V VRRM, but higher VF (1.2 V @ 3 A) and higher IR (50 μA @ 100 V, 25 °C) | Suitable for lower-frequency, less thermally constrained designs where leakage and conduction loss are less critical | Select GI501-E3/73 when lower VF and tighter IR spec are needed for efficiency-sensitive or high-temperature operation |
| GBU2K | Bridge rectifier (4-diode GBU package), 200 V VRRM, 2 A IF(AV); not single-diode or pin-compatible | Used where full-wave bridge integration is preferred over discrete diodes; requires different footprint and wiring | Choose GI501-E3/73 for discrete, space-constrained, or cost-optimized single-diode implementations requiring exact 100 V rating |
Compared with 1N5401G and GBU2K, GI501-E3/73 delivers superior leakage performance (5.0 vs. 50 μA) and lower forward drop (1.1 V vs. 1.2 V), making it preferable in thermally limited or low-quiescent designs-though it lacks the integrated bridge convenience of GBU2K or the broader vendor availability of 1N5401G.

FAQ
What is the maximum junction temperature rating for GI501-E3/73?
The GI501-E3/73 has a maximum operating junction temperature (TJ max.) of +150 °C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in high-ambient environments such as enclosed power supplies or industrial enclosures, provided thermal design respects the 20 °C/W RθJA value with appropriate PCB copper area. Derating curves confirm usable current down to –50 °C storage and operation.
Does GI501-E3/73 have AEC-Q101 qualification?
No, GI501-E3/73 is explicitly stated as not AEC-Q101 qualified in the datasheet notes. It is designated for commercial-grade applications only. For automotive use, engineers must perform additional qualification or select Vishay's AEC-Q101-certified alternatives such as the VS-GBPCxx series or specific automotive-grade rectifiers-not GI501-E3/73.
What does the "/73" suffix indicate in GI501-E3/73?
The "/73" suffix in GI501-E3/73 denotes the packaging configuration: ammo pack packaging with a base quantity of 1000 units. This differs from "/54", which indicates 13" diameter paper tape and reel (1400 units). Both share identical electrical and thermal specifications; only logistics and handling differ. The "E3" prefix confirms RoHS-compliant, commercial-grade construction.
How does the reverse recovery time of GI501-E3/73 affect its use in switching converters?
With a typical trr of 2.0 μs, GI501-E3/73 is suitable for switching frequencies up to approximately 100 kHz in flyback or forward converters. Faster recovery reduces tail current and associated switching losses-but at >100 kHz, soft-recovery or ultrafast diodes (e.g., UF4007) may be preferred. The 2.0 μs value was measured under standardized conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), enabling direct comparison with other rectifiers.
Can GI501-E3/73 replace GI500-E3/73 in a design?
GI501-E3/73 can replace GI500-E3/73 only if the circuit requires ≥100 V VRRM-GI500 is rated for 50 V, while GI501 is rated for 100 V. All other parameters (IF(AV), IFSM, VF, IR, package) are identical. Substitution is electrically safe where higher reverse voltage margin is acceptable or required, but not vice versa. No PCB changes are needed since both use DO-201AD.
