Product details
Overview
1N6302AHE3_B/C 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 171 V to 189 V breakdown voltage range at 1 mA, 154 V maximum standoff voltage, 1500 W peak pulse power (10/1000 μs), 6.1 A peak pulse current, and clamps transients to ≤246 V. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6302AHE3_B/C datasheet, 1N6302AHE3_B/C pinout, 1N6302AHE3_B/C application, or 1N6302AHE3_B/C equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance data, and real-world protection use cases - all confirmed from Vishay's official 88301 specification document.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device with glass-passivated junction construction, enabling sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse power rating is defined under standardized 10/1000 μs waveform conditions with 0.01% duty cycle.
The device exhibits a temperature coefficient of breakdown voltage of +0.108 %/°C and supports operating junction temperatures from –55 °C to +175 °C. It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and has a maximum instantaneous forward voltage of 5.0 V at 100 A - consistent with devices ≥1.5KE250A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 171 V min / 189 V max at 1 mA - defines precise clamping initiation threshold for overvoltage events |
| Standoff Voltage VWM | 154 V max - ensures reliable blocking during normal 150 V DC rail operation without leakage conduction |
| Peak Pulse Power PPPM | 1500 W (10/1000 μs) - sustains high-energy lightning or ESD transients without failure |
| Clamping Voltage VC | ≤246 V at 6.1 A IPPM - limits downstream component stress to safe levels during surge |
| Operating Temperature | –55 °C to +175 °C - enables deployment in under-hood automotive and industrial ambient environments |
| Thermal Resistance RθJL | 15.4 °C/W - allows direct lead-to-heat sink thermal path for sustained power dissipation |

| Cathode | Current exit terminal; marked with color band | Connected to line being protected (e.g., 12 V rail); reverse-biased during normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repetitive surge stress |

| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot during transient suppression, reducing risk of latch-up or gate oxide damage in downstream ICs |
| Solderability per J-STD-002/JESD 22-B102 | Ensures robust reflow and wave solder joint integrity in high-volume manufacturing environments |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a, up to 60 V/100 ms) and coupled transients. IC Role / Device Role: Primary clamping element placed between power rail and ground, upstream of DC/DC converter input. Use Value: Limits input voltage to ≤246 V during 1500 W surges, preventing damage to input MOSFETs and controller ICs while maintaining AEC-Q101 compliance. |
Use Scenario: 4–20 mA current loop or analog voltage output (0–10 V) from pressure/temperature sensors in factory automation. IC Role / Device Role: Unidirectional shunt protector on sensor output line, referenced to system ground. Use Value: Clamps induced EFT/burst noise (IEC 61000-4-4) and cable discharge events to <246 V, preserving ADC accuracy and isolator integrity. |
| Telecom DC Power Feeds | Consumer Power Adapter Output Protection |
Use Scenario: –48 V DC distribution in telecom base station cabinets subject to lightning-induced surges on long interconnects. IC Role / Device Role: Reverse-polarity tolerant clamp (cathode to –48 V rail, anode to ground) protecting rectifier and supervisor ICs. Use Value: Withstands 1500 W pulses without degradation; 175 °C max junction temperature supports operation in sealed, high-ambient enclosures. |
Use Scenario: Secondary-side 5 V/12 V outputs of wall adapters exposed to user-handling ESD and mains-coupled transients. IC Role / Device Role: Final-stage overvoltage guard before USB ports or microcontroller power pins. Use Value: Sub-ns response ensures clamping before LDO or PMIC overvoltage shutdown triggers, avoiding brownout resets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE180AHE3_A | Same VBR range (171–189 V), identical 1.5KE package, but HE3_A revision lacks AEC-Q101 qualification per note (2) in doc 88301 | Not approved for automotive use; suitable only for commercial/industrial applications where qualification is not mandated | Select 1N6302AHE3_B/C when AEC-Q101 compliance is required; choose 1.5KE180AHE3_A for cost-sensitive non-automotive designs. |
| SMBJ180A | Lower PPPM (600 W), smaller SMB package (4.5 × 3.9 × 2.3 mm), higher VC/VBR ratio (~1.5), same unidirectional polarity | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 without parallel staging | Use SMBJ180A where board space is constrained and surge energy is ≤600 W; retain 1N6302AHE3_B/C for full 1500 W capability in legacy 1.5KE footprints. |
Compared with 1.5KE180AHE3_A, 1N6302AHE3_B/C adds AEC-Q101 qualification for automotive deployment; compared with SMBJ180A, it delivers 2.5× higher pulse power in a larger, thermally superior package - critical for single-device compliance with harsh industrial and automotive surge standards.

FAQ
What is the exact breakdown voltage range for 1N6302AHE3_B/C?
The 1N6302AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 171 V minimum to 189 V maximum, measured at 1 mA test current per Vishay document 88301. This range ensures predictable clamping onset across production lots and temperature extremes, supporting robust overvoltage design margins in 150 V nominal systems.
Is 1N6302AHE3_B/C bidirectional or unidirectional?
The 1N6302AHE3_B/C is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its designation. It conducts only in reverse bias during overvoltage events and features a cathode band marking. Bidirectional variants (e.g., 1N6302CA) are separate part numbers not applicable to this device.
Does 1N6302AHE3_B/C meet AEC-Q101 reliability standards?
Yes - the "HE3_B/C" suffix explicitly denotes AEC-Q101 qualification per Vishay document 88301, note (2). This applies to the full 1.5KE6.8AHE3_B through 1.5KE220AHE3_B series, confirming validated performance under temperature cycling, humidity, and mechanical stress tests required for automotive electronics.
What is the maximum clamping voltage of 1N6302AHE3_B/C at rated surge current?
The 1N6302AHE3_B/C clamps to a maximum of 246 V at its rated peak pulse current (IPPM) of 6.1 A, tested with a 10/1000 μs waveform. This value is critical for determining whether downstream components (e.g., 200 V-rated MOSFETs or 250 V capacitors) remain within safe operating limits during surge events.
Can 1N6302AHE3_B/C replace older 1N6302A parts in existing designs?
Yes - the 1N6302AHE3_B/C maintains identical electrical specifications and 1.5KE package dimensions as legacy 1N6302A, while adding RoHS compliance and AEC-Q101 qualification. No PCB layout changes are needed; however, verify that the HE3_B/C's higher thermal resistance tolerance (175 °C TJ max) aligns with your system's thermal profile.
