Product details
Overview
1N6292HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 75 V breakdown voltage (VBR = 71.3–78.8 V at 1 mA), 64.1 V maximum working voltage (VWM), 104 V clamping voltage (VC) at 14.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6292HE3/73 datasheet, 1N6292HE3/73 pinout, 1N6292HE3/73 application, or 1N6292HE3/73 equivalent, this part delivers verified AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin-plated leads, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molded epoxy packaging - critical for automotive, industrial, and telecom surge protection design-in.
Technical Context
This TVS diode operates as a silicon avalanche clamp, responding within <1 ns to transient overvoltages and diverting surge current away from protected circuitry. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance and excellent clamping ratio (VC/VWM ≈ 1.62), ensuring tight voltage limiting during 1500 W pulses.
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable performance under sustained surge duty cycles up to 0.01 % with proper PCB copper thermal relief. The 1.5KE case style provides mechanical robustness and solderability per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines precise avalanche onset threshold for repeatable clamping behavior |
| VWM | 64.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 104 V at 14.6 A - clamped voltage seen by protected load during full 1500 W transient event |
| PPPM | 1500 W - peak pulse power handling capability with standard 10/1000 µs waveform |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for input rectifier stage protection |
| TJ max. | +175 °C - enables high-temperature deployment in engine control units and industrial motor drives |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 compliant epoxy body |
Pinout & Package
1N6292HE3/73 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package: cathode marked by color band on body; anode and cathode leads extend symmetrically from opposite ends. Leads are matte tin-plated, solderable per J-STD-002, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; connected to lower-potential side of protected line | Enables bidirectional surge shunting only when paired with complementary device; used alone for DC rail clamping |
| Cathode (banded end) | Current exit point in forward bias; connected to higher-potential side or ground reference | Defines unidirectional conduction path - critical for correct orientation in power supply input protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, low-leakage avalanche characteristics over lifetime and temperature cycling |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including powertrain and body electronics per stress test requirements |
| 1500 W peak pulse power (10/1000 µs) | Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges |
| Clamping voltage ≤104 V at 14.6 A | Limits voltage overshoot to safe levels for 75 V-rated downstream components such as gate drivers and ADC references |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth in high-reliability environments like automotive ECUs and avionics |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power inputs from load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed between VIN and GND, absorbing energy before it reaches LDO or DC-DC converter. Use Value: Clamps transients to ≤104 V while sustaining 1500 W pulses - preventing brownout, latch-up, or permanent damage to MCU and CAN transceivers. |
Use Scenario: Shielding analog front-end inputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed across sensor signal and ground, suppressing ESD and cable-coupled noise. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC inputs exceed absolute maximum ratings. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Output Clamping |
Use Scenario: Safeguarding Ethernet PHY power pins and data lines against lightning-induced surges on outdoor telecom equipment. IC Role / Device Role / Timing Role: Secondary-level TVS on 3.3 V/5 V bias rails, coordinated with upstream gas discharge tubes (GDTs). Use Value: Low VC/VWM ratio (1.62) maintains margin below IC absolute max ratings while surviving repeated 10/1000 µs events. |
Use Scenario: Preventing output overvoltage damage in AC-DC adapters due to feedback loop failure or Zener regulator fault. IC Role / Device Role / Timing Role: Final-stage clamp on regulated DC output, triggered only during catastrophic failure modes. Use Value: 200 A IFSM rating handles short-duration overcurrent without bond wire fusing - enabling fail-safe shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A-E3/52 | DO-214AA (SMB) package; 75 V VBR; 100 V VC @ 15.2 A; 600 W PPPM | Lower power rating suits space-constrained consumer designs; not AEC-Q101 qualified | Select when board area is limited and 600 W surge immunity suffices; verify thermal relief for SMB footprint |
| 1.5KE75AHE3_A | Same 1.5KE package and electrical specs; HE3_A = earlier revision vs. HE3/73's HE3_B qualification level | No functional difference; HE3/73 includes updated AEC-Q101 test reporting per revision B | Prefer 1N6292HE3/73 for new automotive designs requiring latest qualification evidence |
Compared with SMBJ75A-E3/52, 1N6292HE3/73 offers 2.5× higher pulse power and automotive qualification but requires larger axial footprint; versus 1.5KE75AHE3_A, it provides identical protection with enhanced traceability and revision-controlled AEC-Q101 compliance documentation.

FAQ
What is the exact breakdown voltage range for 1N6292HE3/73?
The 1N6292HE3/73 has a guaranteed breakdown voltage (VBR) range of 71.3 V to 78.8 V at 1 mA test current, measured per JEDEC standards. This specification ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting reliable clamping performance in 75 V system designs.
Is 1N6292HE3/73 suitable for automotive applications?
Yes, 1N6292HE3/73 is AEC-Q101 qualified (HE3 suffix denotes Class 2 whisker testing and full automotive stress validation). It is approved for use in engine control units, body control modules, and infotainment power supplies where transient immunity and long-term reliability under thermal cycling are mandatory.
What does the "/73" suffix indicate in 1N6292HE3/73?
The "/73" suffix in 1N6292HE3/73 specifies tape-and-reel packaging: 73 = 750 pieces per reel, 13" diameter paper tape. This differs from "/54" (1400 pcs/reel) and "/B" (bulk). All electrical and qualification specs remain identical across packaging variants.
How does 1N6292HE3/73 compare to bidirectional TVS diodes?
1N6292HE3/73 is unidirectional and must be oriented with cathode toward the protected circuit's higher potential. Unlike bidirectional types (e.g., 1N6292CA), it cannot suppress AC or symmetrical transients without external polarity conditioning - but offers tighter VWM margin and lower leakage in DC applications.
What is the maximum clamping voltage of 1N6292HE3/73 under surge conditions?
The maximum clamping voltage (VC) of 1N6292HE3/73 is 104 V at 14.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
