Product details
Overview
1N6299HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in the 1.5KE family, designed for primary overvoltage protection of DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 143 V minimum breakdown voltage (VBR), 128 V maximum standoff voltage (VWM), and clamps transients to ≤207 V at 7.2 A peak pulse current - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the 1N6299HE3/54 datasheet, 1N6299HE3/54 pinout, 1N6299HE3/54 application, or 1N6299HE3/54 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, AEC-Q101 qualification status, clamping performance curves, and direct alternative part comparisons for robust ESD and surge protection design-in.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response time (<1 ns) to transient overvoltages. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance, enabling precise clamping during 8/20 µs and 10/1000 µs surge events per IEC 61000-4-5.
The 1N6299HE3/54 is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, with thermal resistance RθJA = 75 °C/W and RθJL = 15.4 °C/W. It supports 200 A non-repetitive forward surge current (8.3 ms half-sine) and maintains ≤1000 µA reverse leakage at VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1 mA test current - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 128 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | ≤207 V at 7.2 A - clamping voltage under 10/1000 µs surge, limiting downstream component stress |
| PPPM | 1500 W - peak pulse power handling capability, enabling protection against lightning-induced surges |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), supporting high-energy transient absorption |
| TJ range | –55 °C to +175 °C - wide operational junction temperature range suitable for under-hood automotive use |
| Leakage @ VWM | ≤1 µA - ensures minimal standby power loss and signal integrity in always-on circuits |
Pinout & Package
Package: JEDEC-standard Case Style 1.5KE - molded epoxy body with matte tin-plated leads, RoHS-compliant, UL 94 V-0 rated, 0.375" (9.5 mm) lead length, 0.042" (1.07 mm) lead diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to protected circuit ground or low-side return path during clamping |
| Cathode (banded end) | Current exit point in forward bias; avalanche conduction node in reverse | Connected to line being protected (e.g., 12 V rail); color band identifies polarity for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade applications including engine control units and body electronics |
| 1500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive systems |
| Sub-nanosecond response time | Clamps transients before sensitive ICs experience damaging overvoltage - critical for protecting CAN, LIN, and sensor interfaces |
| JESD 201 Class 2 whisker resistance | Ensures mechanical stability of tin-plated leads under thermal cycling, preventing solder joint failure in harsh environments |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery feed to infotainment head unit exposed to load dump (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converter input, absorbing >100 V transients within <1 ns.

Use Scenario: AC/DC adapter output feeding BLDC motor driver in smart washing machine control board. IC Role / Device Role / Timing Role: Front-end protection for gate driver IC supply rail against inductive kickback from relay switching and motor commutation. Use Value: Clamps 10/1000 µs surges to ≤207 V, preventing latch-up or gate oxide rupture in high-side MOSFET drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | Lower PPPM (600 W), smaller SMB package (vs. 1.5KE), higher VC/VBR ratio (1.45× vs. 1.45×), same VWM (128 V) | Preferred for space-constrained PCBs where 600 W surge margin suffices; not AEC-Q101 qualified | Select when board area is limited and automotive qualification is not required; verify thermal dissipation in SMB footprint. |
| 1.5KE150AHE3_A | Same electrical specs and 1.5KE package, but HE3_A revision (older AEC-Q101 qualification batch code vs. HE3_B in 1N6299HE3/54) | Identical function and form; differs only in manufacturing lot traceability and revision-level compliance documentation | Use interchangeably where full HE3_B revision documentation is not mandated by OEM audit requirements. |
Compared with SMBJ150A-E3/52, the 1N6299HE3/54 delivers 2.5× higher surge power handling and automotive qualification; compared with 1.5KE150AHE3_A, it offers updated AEC-Q101 certification traceability while maintaining identical clamping and thermal performance.

FAQ
What is the breakdown voltage tolerance for 1N6299HE3/54?
The 1N6299HE3/54 has a specified breakdown voltage (VBR) range of 143 V to 158 V at 1 mA test current, representing ±5% tolerance around the nominal 150 V rating. This tight tolerance ensures predictable clamping onset across production lots and supports consistent system-level surge margin calculations in designs using the 1N6299HE3/54.
Is 1N6299HE3/54 suitable for bidirectional transient protection?
No, the 1N6299HE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. It protects against positive transients on the cathode side and blocks reverse voltage up to VWM = 128 V. For bidirectional protection, Vishay offers the 1N6299CA variant (not 1N6299HE3/54), which lacks polarity marking and clamps in both directions.
What does the "HE3/54" suffix mean in 1N6299HE3/54?
The "HE3" denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification; "/54" specifies packaging in 13" paper tape and reel with 1400 units per reel. This distinguishes it from variants like HE3_B (same qualification, different revision code) or -E3/52 (commercial grade, no AEC-Q101).
How does thermal derating affect 1N6299HE3/54's surge capability?
Per Figure 2 in the Vishay datasheet, the 1N6299HE3/54's peak pulse power (1500 W) is rated at TA = 25 °C and derates linearly to ~800 W at 100 °C ambient. Designers must apply this curve when mounting near heat sources; the 1N6299HE3/54's RθJA = 75 °C/W requires adequate copper pour or heatsinking to maintain clamping performance under sustained high-temperature operation.
Can 1N6299HE3/54 replace older 1N6299A parts in existing designs?
Yes - the 1N6299HE3/54 is a direct functional and mechanical replacement for legacy 1N6299A, with identical electrical specs, 1.5KE package dimensions, and pinout. The HE3/54 adds AEC-Q101 qualification, RoHS compliance, and enhanced whisker resistance, making it suitable for new designs and drop-in upgrades where automotive or high-reliability validation is required.
