Product details
Overview
1.5KE10AHA0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 10V nominal breakdown voltage (VBR = 9.5–10.5V @ 1.0mA), 8.55V working stand-off voltage (VWM), and 14.5V clamping voltage (VC @ 10A). It delivers fast response (<1.0ps), low dynamic impedance, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity.
For engineers reviewing the 1.5KE10AHA0G datasheet, 1.5KE10AHA0G pinout, 1.5KE10AHA0G application, or 1.5KE10AHA0G equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, clamping performance under 10/1000μs surge, thermal derating behavior, and direct alternatives for automotive power rail protection.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device across DC power lines to divert transient energy away from sensitive downstream circuitry. Its junction design enables sub-nanosecond response to voltage spikes, with VBR tightly specified at 9.5–10.5V and guaranteed clamping at ≤14.5V under 10A peak impulse current.
Rated for 1500W peak pulse power (10/1000μs), it sustains 5W steady-state dissipation at 75°C lead temperature and supports 200A non-repetitive forward surge (8.3ms half-sine). The device is AEC-Q101 qualified and RoHS/halogen-free compliant per IEC 61249-2-21.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ10A | Same DO-214AC (SMA) package; 10V VBR (9.0–11.1V), 1500W PPK, but lower IPP (103A vs. 108A for 1.5KE10AHA0G) | Not AEC-Q101 qualified; intended for commercial/industrial use only | Select when automotive qualification is not required and board space favors surface-mount |
| ON Semiconductor 1N6271A | Identical electrical specs (VBR, VC, PPK) and DO-201 package; same 1.0mA test current | No AEC-Q101 option available; lacks automotive stress validation | Use as second-source where AEC-Q101 is not mandated and legacy ON Semi BOMs exist |
Compared with SMAJ10A and 1N6271A, the 1.5KE10AHA0G uniquely combines AEC-Q101 qualification, DO-201 axial-leaded form factor for high-power through-hole mounting, and validated ISO 7637-2 compliance-making it the only choice for production automotive power rails requiring traceable qualification and mechanical robustness.

FAQ
What is the clamping voltage of the 1.5KE10AHA0G under a 10A transient?
The 1.5KE10AHA0G has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10A peak impulse current (IPP) under the standard 10/1000μs waveform. This value is measured and guaranteed per the manufacturer's datasheet, ensuring predictable overvoltage limiting for downstream 12V-rated ICs and regulators in the 1.5KE10AHA0G application circuit.
Is the 1.5KE10AHA0G AEC-Q101 qualified?
Yes, the 1.5KE10AHA0G is AEC-Q101 qualified. The "H" suffix in the part number explicitly denotes AEC-Q101 qualification, and the device undergoes full stress testing per the AEC-Q101 standard for transient voltage suppressors. This makes the 1.5KE10AHA0G suitable for automotive powertrain, body, and chassis applications where component-level reliability validation is mandatory.
What does the "A0G" suffix mean in 1.5KE10AHA0G?
The "A0G" suffix in 1.5KE10AHA0G indicates two key attributes: "A" denotes the tighter VBR tolerance (±5% instead of ±10%), and "0G" specifies green (halogen-free) molding compound compliant with IEC 61249-2-21. The "H" preceding "A0G" confirms AEC-Q101 qualification. Therefore, 1.5KE10AHA0G is a halogen-free, AEC-Q101-qualified, tight-tolerance variant of the 1.5KE10A TVS diode.
Can the 1.5KE10AHA0G be used in bidirectional configurations?
No, the 1.5KE10AHA0G is a unidirectional TVS diode and must not be used in bidirectional applications. Its electrical specifications-including VBR, VC, and leakage-are defined only for forward-biased (cathode-to-anode) operation. For bidirectional protection, Taiwan Semiconductor offers the 1.5KE10CA or 1.5KE10CA0G variants, which feature symmetrical breakdown in both polarities and are explicitly marked as bipolar devices.
What is the maximum steady-state power dissipation for the 1.5KE10AHA0G?
The 1.5KE10AHA0G has a steady-state power dissipation (PD) rating of 5 W at a lead temperature (TL) of 75°C, measured with 0.375-inch (9.5 mm) lead lengths mounted on a 0.6" × 0.6" copper pad. This rating applies only to continuous DC or low-frequency conditions-not to transient events-and must be thermally managed via PCB copper area or heatsinking to avoid exceeding the +175°C maximum junction temperature.
