Product details
Overview
1.5KE10AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 9.5 V minimum breakdown voltage (VBR), 8.55 V standoff voltage (VWM), 14.5 V clamping voltage at 103 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the 1.5KE10AHE3_B/C datasheet, 1.5KE10AHE3_B/C pinout, 1.5KE10AHE3_B/C application, or 1.5KE10AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), JEDEC 1.5KE package dimensions, and direct replacement guidance for circuit-level ESD and lightning surge protection design.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01% duty cycle, enabling robust transient suppression without thermal runaway under repetitive surges.
The device complies with AEC-Q101 stress testing for automotive applications and supports soldering per J-STD-002 and JESD 22-B102. The HE3 suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance and UL 94 V-0 molded epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 9.5 V - Ensures reliable conduction onset above normal operating voltage, preventing false triggering during transients. |
| VWM | 8.55 V - Maximum continuous reverse working voltage; defines safe DC bias margin before leakage increases. |
| VC @ IPPM | 14.5 V - Clamped voltage at 103 A peak pulse; determines maximum stress imposed on protected downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling for 10/1000 µs waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| IPPM | 103 A - Peak pulse current capability; sets minimum surge current threshold the device can safely divert. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| RθJL | 15.4 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements for high-duty-cycle surge events. |
Pinout & Package
Package: JEDEC Case Style 1.5KE - axial-leaded, molded epoxy body (0.375" lead length), UL 94 V-0 rated, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; establishes forward-biased path during positive transients. |
| Cathode | High-side transient input terminal | Connected to protected line; color band identifies cathode end for correct unidirectional orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under humidity and thermal cycling. |

| Sub-nanosecond response | Clamps transients within <1 ns - faster than MOVs or polymer-based protectors - preserving signal integrity in high-speed interfaces. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high-temperature/humidity conditions, critical for long-life automotive modules. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects 12 V supply rail from load-dump spikes (up to 35 V, 100 ms) and alternator ripple-induced transients. IC Role / Device Role / Timing Role: Primary clamping element placed between fused battery feed and LDO regulator input. Use Value: Limits voltage seen by downstream PMIC to ≤14.5 V during 103 A surge, preventing latch-up or gate oxide damage. |
Use Scenario: Shields 24 V digital input optocoupler interface from inductive kickback when controlling solenoids or relays. IC Role / Device Role / Timing Role: Standoff protector mounted directly at PCB edge connector, shunting energy before signal conditioning stage. Use Value: Clamps 1 kV/0.5 A surge (IEC 61000-4-4) to <15 V within 1 ns, maintaining logic-level compatibility with microcontroller GPIO. |
| Telecom Remote Radio Unit (RRU) Power Interface | Consumer Appliance Motor Drive Board |
Use Scenario: Guards PoE-powered RF front-end circuitry against lightning-induced surges on outdoor Ethernet cabling. IC Role / Device Role / Timing Role: First-stage protector on DC input side of isolated DC/DC converter, upstream of TVS arrays. Use Value: Absorbs 1500 W transient energy without degradation, enabling compliance with ITU-T K.21 light industrial surge requirements. |
Use Scenario: Suppresses commutation spikes from brushed DC motors driving washing machine drum assemblies. IC Role / Device Role / Timing Role: Unidirectional clamp across motor terminals, referenced to chassis ground to limit flyback voltage. Use Value: Holds back-EMF below 15 V during 100 A switching events, preventing MOSFET avalanche failure and EMI radiation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower PPPM (600 W), smaller SMB package (vs. axial 1.5KE), higher VC (17.0 V @ 35.1 A) | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs, not under-hood automotive. | Select when board area is constrained and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE10CA | Bidirectional variant; same VBR, VWM, and PPPM, but symmetrical clamping for AC-coupled or floating lines. | Required for RS-485, CAN bus, or audio line protection where polarity reversal occurs. | Choose only if bidirectional clamping is needed - unidirectional 1.5KE10AHE3_B/C is not pin-compatible. |
Compared with SMBJ10A and 1.5KE10CA, the 1.5KE10AHE3_B/C provides higher surge robustness and automotive qualification in an axial through-hole package ideal for high-reliability power rail protection, while avoiding layout changes required for surface-mount alternatives or functional mismatches of bidirectional variants.

FAQ
What is the breakdown voltage tolerance for 1.5KE10AHE3_B/C?
The 1.5KE10AHE3_B/C has a specified breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1.0 mA test current, representing a ±5% tolerance. This tight tolerance ensures predictable turn-on behavior during overvoltage events and supports consistent protection margins across production lots.
Is 1.5KE10AHE3_B/C suitable for automotive applications?
Yes, the 1.5KE10AHE3_B/C is AEC-Q101 qualified per Vishay documentation (Rev. 09-Aug-2022, Doc. 88301), covering stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. Its –55 °C to +175 °C operating range and JESD 201 Class 2 whisker resistance make it appropriate for engine control units and body electronics.
How does the clamping voltage of 1.5KE10AHE3_B/C compare to its standoff voltage?
The 1.5KE10AHE3_B/C has a maximum standoff voltage (VWM) of 8.55 V and a clamping voltage (VC) of 14.5 V at 103 A. This 5.95 V differential ensures sufficient margin above normal operating voltage while limiting stress on protected ICs to a safe, known ceiling during surge events.
What is the thermal resistance from junction to lead for 1.5KE10AHE3_B/C?
The 1.5KE10AHE3_B/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, measured with 0.375" (9.5 mm) lead length. This value is critical for estimating temperature rise during repetitive surge events and informs heatsink or copper pour design on PCBs handling frequent transients.
Can 1.5KE10AHE3_B/C be used in bidirectional signal lines like RS-485?
No - the 1.5KE10AHE3_B/C is unidirectional and must be oriented with cathode toward the protected line. For bidirectional lines such as RS-485 or CAN, the bidirectional variant 1.5KE10CA is required; it provides symmetrical clamping in both polarities and is not interchangeable with 1.5KE10AHE3_B/C.
