Product details
Overview
1N6286AHE3_B/C 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 40.9 V to 45.2 V breakdown voltage range at 1 mA test current, 36.8 V maximum standoff voltage, 1.0 µA max reverse leakage at VWM, 25.3 A peak pulse current (10/1000 µs), and clamps transients to 59.3 V at rated IPPM - used in automotive power supply inputs, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the 1N6286AHE3_B/C datasheet, 1N6286AHE3_B/C pinout, 1N6286AHE3_B/C application, or 1N6286AHE3_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 device operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable clamping action only in CA-suffix variants - the 1N6286AHE3_B/C is unidirectional, with cathode marked by color band. Its 1500 W peak pulse power rating applies under 10/1000 µs waveform at 0.01% duty cycle, and it exhibits 0.101 %/°C temperature coefficient of VBR.
Clamping response is effectively instantaneous (≤1 ns), with low incremental surge resistance enabling fast suppression of ESD, lightning-induced surges, and inductive switching transients. The device supports operation from –55 °C to +175 °C junction temperature and meets JESD 201 Class 2 whisker resistance via HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min / max | 40.9 V / 45.2 V at IT = 1 mA - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 36.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 25.3 A (10/1000 µs) - peak transient current the device safely shunts without failure |
| VC at IPPM | 59.3 V - clamped voltage seen by protected circuit during full-rated surge event |
| PPPM | 1500 W - peak pulse power dissipation capability under standardized surge waveform |
| TJ max | +175 °C - maximum junction temperature enabling high-temperature automotive and industrial deployment |
| RθJL | 15.4 °C/W - thermal resistance from junction to lead, critical for PCB copper pour and heatsinking design |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |

| Low RθJL = 15.4 °C/W | Allows direct lead-to-PCB thermal coupling without external heatsink for intermittent surge duty |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 16750-2) and jump-start transients. IC Role / Device Role: Primary overvoltage clamp placed between input rail and ground, upstream of DC/DC converter. Use Value: Limits rail voltage to ≤59.3 V during 25.3 A surge, preventing damage to LDOs and microcontrollers rated for 40 V absolute max. |
Use Scenario: Analog output (4–20 mA) or digital (CAN/LIN) sensor lines routed through noisy factory environments. IC Role / Device Role: Unidirectional TVS connected between signal line and chassis ground to suppress coupled EFT and surge noise. Use Value: Clamps induced transients within 1 ns while maintaining <1.0 µA leakage at 36.8 V, preserving signal integrity and ADC accuracy. |
| Telecom AC/DC Adapter Input | Motor Drive Control Board Surge Guard |
Use Scenario: Secondary-side rectified output of offline SMPS powering VoIP phones or base stations. IC Role / Device Role: Standoff-rated TVS protecting downstream regulators and PHY ICs from transformer-coupled surges. Use Value: Withstands repetitive 1500 W pulses at 0.01% duty cycle and maintains VWM = 36.8 V to avoid false triggering during normal 36 V nominal operation. |
Use Scenario: Gate drive or feedback signal traces near IGBT/MOSFET half-bridges subject to Miller-induced dv/dt spikes. IC Role / Device Role: Localized TVS on isolated gate driver outputs or current sense amplifier inputs. Use Value: Fast 1 ns response prevents latch-up in precision amplifiers; 59.3 V clamping protects 36 V-rated op-amps and isolators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/52 | Lower PPPM (600 W), smaller SMB package (RθJA = 110 °C/W), VBR = 40–44.4 V | Better suited for space-constrained consumer PCBs; insufficient for ISO 16750-2 load dump without parallel devices | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2 (1 kV/42 Ω) |
| 1.5KE43AHE3_A | Same electrical specs and DO-201AD package, but AEC-Q101 qualified only up to revision A (not B/C) | Acceptable for legacy automotive programs where qualification revision level is not enforced | Choose only if documentation traceability to HE3_B/C revision is not required for PPAP submission |
Compared with SMBJ36A-E3/52, the 1N6286AHE3_B/C delivers 2.5× higher surge power handling and superior thermal performance via lower RθJL; versus 1.5KE43AHE3_A, it provides updated AEC-Q101 qualification evidence aligned with current automotive audit requirements.

FAQ
What is the breakdown voltage tolerance of the 1N6286AHE3_B/C?
The 1N6286AHE3_B/C has a specified breakdown voltage range of 40.9 V to 45.2 V at 1 mA test current (VBR min/max), corresponding to ±5% tolerance around the nominal 43 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable overvoltage margining in safety-critical designs.
Is the 1N6286AHE3_B/C suitable for bidirectional transient suppression?
No - the 1N6286AHE3_B/C is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., 1.5KE43CA). Using the 1N6286AHE3_B/C in bidirectional applications would result in forward conduction during negative transients, potentially causing failure or incorrect clamping.
Does the 1N6286AHE3_B/C meet AEC-Q101 requirements?
Yes - the HE3_B/C suffix confirms AEC-Q101 qualification per Vishay Document 88301 Note (2), covering devices from 1.5KE6.8AHE3_B to 1.5KE220AHE3_B. This includes stress testing for high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validated for automotive under-hood and chassis applications.
What is the maximum clamping voltage of the 1N6286AHE3_B/C at rated surge current?
The 1N6286AHE3_B/C clamps to a maximum of 59.3 V when subjected to its rated 25.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 7 in Vishay's 88301 datasheet and represents the worst-case voltage imposed on the protected circuit during full-rated surge events.
How does the thermal resistance of the 1N6286AHE3_B/C impact PCB layout?
The 1N6286AHE3_B/C has RθJL = 15.4 °C/W (junction-to-lead), meaning effective heat transfer relies on generous copper pour connected directly to its leads. For sustained surge duty, designers must allocate ≥25 mm² of 2-oz copper per lead; inadequate copper increases junction temperature and reduces surge endurance - especially critical in automotive under-hood deployments above 85 °C ambient.
