Product details
Overview
1N6290HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, 53.0 V stand-off voltage (VWM), and operates from –55 °C to +175 °C - used in automotive power supply input stages and industrial DC bus protection.
For engineers reviewing the 1N6290HE3/73 datasheet, 1N6290HE3/73 pinout, 1N6290HE3/73 application, or 1N6290HE3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), and real-world design guidance for transient suppression in high-reliability 12–48 V systems.
Technical Context
This device implements a silicon avalanche junction structure with glass passivation for stable breakdown and low leakage. Its unidirectional polarity uses a cathode band marking, and it complies with JEDEC case style 1.5KE - a molded epoxy DO-201AD package rated for 200 A non-repetitive forward surge (IFSM) and 6.5 W steady-state power dissipation at TL = 75 °C.
The 1N6290HE3/73 delivers sub-nanosecond response time (<1 ns) and low incremental surge resistance, enabling effective clamping of lightning-induced transients (per R.E.A. P.E. 60) and inductive switching spikes on 24 V control circuits. Its 0.104 %/°C temperature coefficient of VBR ensures predictable voltage margin across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise avalanche initiation window for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs waveform) - peak surge energy handling capacity for industrial-grade protection |
| IFSM | 200 A (8.3 ms half-sine) - supports robust inrush and fault-current survival in power supplies |
| TJ max. | +175 °C - enables under-hood automotive deployment without derating in high-ambient environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance allows direct PCB copper pour heatsinking |
Pinout & Package
Package: DO-201AD (JEDEC 1.5KE), molded epoxy body with matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Avalanche breakdown node / high-voltage reference | Marked with band; tied to line being protected (e.g., 24 V rail); defines VWM and VBR thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures long-term stability of VBR and low leakage (<1 µA at VWM) over 15+ year automotive service life |

| Sub-ns response time | Clamps transients before IC damage occurs - critical for protecting CAN transceivers and MCU I/O pins |
| Low RθJL (15.4 °C/W) | Enables >90 % of surge energy to dissipate through PCB copper, reducing need for external heatsinks |
Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 24 V battery-fed ECU input subjected to load dump (ISO 16750-2) and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed between battery rail and DC-DC converter input. Use Value: Limits voltage to ≤85 V during 17.6 A surge, preventing damage to upstream regulators and ensuring system reset integrity. | Use Scenario: 24 V digital input module exposed to relay coil flyback and field wiring ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS shunting transient energy directly to common ground before signal conditioning circuitry. Use Value: Clamps 1 kV/50 Ω IEC 61000-4-2 contact discharge within <1 ns, preserving optocoupler and microcontroller GPIO reliability. |
| Telecom DC Power Feeds | Motor Drive Control Signal Lines |
Use Scenario: -48 V telecom rectifier output feeding base station backplane with lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Standoff-rated TVS on power entry point, coordinated with upstream MOVs for staged protection. Use Value: Withstands repetitive 10/1000 µs surges up to 1500 W while maintaining VWM = 53 V to avoid false triggering on nominal -48 V rail ripple. | Use Scenario: PWM enable line from PLC to 3-phase inverter gate driver, subject to cross-talk and ground bounce. IC Role / Device Role / Timing Role: Localized TVS at driver input to suppress fast-rising edge-induced coupling (dV/dt > 100 V/ns). Use Value: Sub-ns response prevents false turn-on of IGBTs/MOSFETs, eliminating shoot-through risk during high-speed switching transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | DO-214AA package (smaller footprint), 64 V VBR, 600 W PPPM, higher RθJA (90 °C/W) | Lower power handling limits use to consumer-grade 12 V systems; unsuitable for ISO 16750-2 load dump | Select when board space is constrained and surge energy is ≤600 W (e.g., USB-C PD adapters) |
| 1.5KE62AHE3_A | Same 1.5KE package and VBR range, but commercial-grade (non-AEC-Q101), JESD201 Class 1A whisker rating | Lacks automotive qualification testing; not approved for under-hood or safety-critical modules | Acceptable for industrial controls where AEC-Q101 is not mandated and cost sensitivity outweighs qualification needs |
Compared with 1N6290HE3/73, SMBJ64A-E3/52 trades power density for compactness and cost, while 1.5KE62AHE3_A retains mechanical compatibility but omits automotive stress validation - making 1N6290HE3/73 the only option qualified for both high-energy surge handling and automotive deployment.

FAQ
What is the breakdown voltage tolerance of the 1N6290HE3/73?
The 1N6290HE3/73 has a specified breakdown voltage range of 58.9 V to 65.1 V at a test current of 1.0 mA. This ±5.2 % tolerance ensures consistent clamping behavior across production lots and supports reliable coordination with downstream overvoltage protection circuits. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is the 1N6290HE3/73 suitable for automotive applications?
Yes, the 1N6290HE3/73 is AEC-Q101 qualified per Vishay documentation (note 2 on page 3 of document 88301), covering HTOL, temperature cycling, and HTRB stress tests. Its 175 °C max junction temperature, 200 A IFSM, and DO-201AD package with JESD201 Class 2 whisker resistance make it appropriate for under-hood engine control units and body electronics where ISO 16750-2 compliance is required.
How does the clamping voltage of the 1N6290HE3/73 compare to its breakdown voltage?
The 1N6290HE3/73 clamps at 85.0 V when subjected to its peak pulse current of 17.6 A (10/1000 µs), resulting in a clamping ratio of 1.30× VBR (using VBR = 65.1 V max). This low ratio reflects efficient avalanche conduction and minimal incremental surge resistance - critical for protecting 75 V-rated downstream components in 24 V systems.
What is the thermal resistance from junction to lead (RθJL) for the 1N6290HE3/73?
The 1N6290HE3/73 has a typical junction-to-lead thermal resistance of 15.4 °C/W, as specified in the Thermal Characteristics table (page 3, document 88301). This low value enables effective heat transfer to PCB copper pours or chassis mounts, supporting sustained operation at elevated ambient temperatures without forced cooling - especially valuable in sealed automotive enclosures.
Does the 1N6290HE3/73 have bidirectional capability?
No, the 1N6290HE3/73 is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE62CA). Using the 1N6290HE3/73 in AC or floating-bus applications would require external polarity management or selection of a CA-series part.
