Product details
Overview
1.5KE10HE3/54 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 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 10.3 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range. It is RoHS-compliant, AEC-Q101 qualified, and used to protect MOSFETs and ICs against inductive switching transients.
For engineers reviewing the 1.5KE10HE3/54 datasheet, 1.5KE10HE3/54 pinout, 1.5KE10HE3/54 application, or 1.5KE10HE3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under standardized surge waveforms, and real-world protection use cases in automotive and industrial power systems.
Technical Context
The 1.5KE10HE3/54 employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 100 A, with breakdown voltage (VBR) specified between 9.5 V and 10.5 V at 1 mA test current.
It complies with JEDEC standards for surge testing (8.3 ms half-sine, 10/1000 µs waveform), supports repetitive surge duty cycles up to 0.01 %, and is rated for 200 A non-repetitive forward surge current. Thermal resistance is 15.4 °C/W junction-to-lead, enabling effective heat dissipation in leaded PCB mounting configurations.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients during alternator regulation failure. IC Role / Device Role / Timing Role: Primary clamping device placed directly across input rail, absorbing >100 V spikes within <1 ns. Use Value: Limits rail voltage to ≤14.5 V during 10.3 A surge, preventing gate oxide rupture in protected buck controllers and CAN transceivers. | Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Unidirectional shunt protector on sensor supply line, triggered only during positive-going transients induced by relay switching. Use Value: Maintains signal integrity by clamping induced surges before they reach precision ADC inputs, avoiding offset drift or latch-up. |
| DC Motor Drive Gate Protection | Telecom Power Supply Input Stage |
Use Scenario: Shielding high-side N-channel MOSFET gates from inductive kickback when driving brushed DC motors in robotics. IC Role / Device Role / Timing Role: Connected anode-to-ground, cathode-to-gate; clamps negative-going gate-source voltage excursions below –14.5 V. Use Value: Prevents gate-source overvoltage failure while preserving fast switching speed due to sub-nanosecond response. | Use Scenario: Front-end surge suppression on 48 V telecom rectifier outputs feeding distributed power modules. IC Role / Device Role / Timing Role: First-line TVS in series with input filter, handling repetitive lightning-induced surges on outdoor plant equipment. Use Value: Withstands 0.01 % duty cycle surges up to 1500 W without parameter shift, ensuring multi-year field reliability. |
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, 14.5 V VC at 43.3 A | Designed for board space-constrained designs; not AEC-Q101 qualified | Select when footprint reduction is prioritized over automotive qualification and 1500 W surge headroom |
| 1.5KE10A | Same electrical specs but E3 suffix only (not HE3); no AEC-Q101 qualification or JESD 201 Class 2 whisker rating | Commercial-grade use only; unsuitable for automotive or long-lifecycle industrial deployments | Choose only for cost-sensitive consumer applications where extended reliability validation is unnecessary |
Compared with 1.5KE10HE3/54, SMBJ10A trades surge capacity and qualification for compactness, while 1.5KE10A retains identical clamping but lacks automotive-grade process controls and whisker mitigation-making 1.5KE10HE3/54 the sole option for AEC-Q101-compliant 1500 W protection in harsh environments.

FAQ
What is the clamping voltage of the 1.5KE10HE3/54 under a standard 10/1000 µs surge?
The 1.5KE10HE3/54 has a maximum clamping voltage (VC) of 14.5 V at 10.3 A peak pulse current, measured using the standardized 10/1000 µs waveform per IEC 61000-4-5. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The 1.5KE10HE3/54 maintains this clamping performance across its full operating temperature range and after repeated surge exposure, thanks to its glass-passivated junction and AEC-Q101-qualified construction.
Is the 1.5KE10HE3/54 suitable for automotive applications?
Yes, the 1.5KE10HE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance requirements, making it suitable for automotive powertrain, body control, and ADAS subsystems. Its –55 °C to +175 °C operating junction temperature range, 1500 W surge rating, and validated reliability under thermal cycling confirm its readiness for under-hood deployment. The 1.5KE10HE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the 1.5KE family.
How does the HE3 suffix differ from the standard E3 suffix in the 1.5KE10HE3/54 part number?
The HE3 suffix in 1.5KE10HE3/54 denotes both RoHS compliance and AEC-Q101 qualification, plus JESD 201 Class 2 whisker resistance-whereas E3-only variants (e.g., 1.5KE10A-E3) are commercial-grade only. The "H" prefix confirms enhanced process controls, extended reliability testing, and traceable manufacturing for automotive and industrial applications. For the 1.5KE10HE3/54, this means guaranteed performance in high-vibration, high-temperature environments where standard 1.5KE10A parts would not be approved.
What is the standoff voltage (VWM) and why is it important for the 1.5KE10HE3/54?
The 1.5KE10HE3/54 has a maximum standoff voltage (VWM) of 8.55 V, meaning it remains non-conductive under normal operating conditions up to that voltage. This margin prevents leakage current and power loss during steady-state operation while allowing immediate avalanche conduction when transients exceed VWM. For the 1.5KE10HE3/54, this 1.45 V differential between VWM and nominal 12 V rail systems provides safe headroom against ripple and tolerance drift-ensuring reliable protection without false triggering.
Can the 1.5KE10HE3/54 be used in bidirectional configurations?
No, the 1.5KE10HE3/54 is a unidirectional TVS diode, indicated by the absence of "C" in its part number (e.g., 1.5KE10CA would be bidirectional). Its cathode band must be oriented toward the higher-potential side of the protected line. Bidirectional operation requires a CA-suffixed variant, and Vishay specifies that 1.5KE10CA-not 1.5KE10HE3/54-is the correct part for AC or dual-polarity surge protection. Using the 1.5KE10HE3/54 in bidirectional roles risks forward conduction failure during negative transients.
