Product details
Overview
P6KE110AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 110V nominal breakdown voltage (VBR min/max: 99–121V), 89.2V stand-off voltage (VWM), 152V maximum clamping voltage at 4.1A peak surge current, and low dynamic impedance for effective ESD and lightning-induced transient suppression in automotive and industrial systems.
For engineers reviewing the P6KE110AH datasheet, P6KE110AH pinout, P6KE110AH application, or P6KE110AH equivalent, this device is selected for high-reliability DC bus protection where AEC-Q101 qualification, fast sub-nanosecond response (<1.0ps), and stable clamping under 10/1000μs surges are critical design requirements.
Technical Context
The P6KE110AH operates as a unidirectional avalanche diode with a single-die DO-204AC (DO-15) package and cathode-band polarity marking. Its junction temperature range spans −55°C to +175°C, and it delivers 600W non-repetitive peak pulse power at 10/1000μs waveform with derating above 25°C ambient per published curve.
It exhibits <1μA reverse leakage at 89.2V (VWM), a 0.107%/°C VBR temperature coefficient, and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards. The device is AEC-Q101 qualified - explicitly confirmed for P6KE110AH in ordering code documentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same 110V nominal, but 600W rating in SMB package; lower thermal resistance (junction-to-case ≈ 20°C/W vs. DO-15's ≈ 50°C/W) | Preferred for surface-mount PCBs with space constraints; less suitable for through-hole high-vibration mounts | Select SMBJ110A for SMT designs needing better thermal performance; P6KE110AH remains optimal for legacy through-hole layouts and mechanical robustness. |
| 1.5KE110A | Same DO-204AC package and 110V rating, but 1500W peak power (10/1000μs); larger die, higher clamping voltage (173V @ 8.7A) | Used where higher surge margin is required (e.g., utility meter mains input), but adds cost and board area | Choose 1.5KE110A only if system-level surge testing exceeds 600W; P6KE110AH provides optimal balance of size, cost, and 600W compliance. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110AH offers AEC-Q101 qualification and DO-15 mechanical stability unmatched by SMBJ, while delivering lower clamping voltage than 1.5KE - making it the preferred choice for automotive and industrial through-hole TVS applications demanding reliability, compact axial form, and precise 152V clamping.

FAQ
What is the clamping voltage of the P6KE110AH under standard surge conditions?
The P6KE110AH has a maximum clamping voltage (VC) of 152 V at 4.1 A peak pulse current (IPP), measured under the standardized 10/1000 μs double-exponential surge waveform. This value ensures protected downstream components experience no more than 152 V during transient events, aligning with IEC 61000-4-5 Level 4 immunity requirements. The P6KE110AH maintains this clamping performance across its full operating temperature range.
Is the P6KE110AH suitable for automotive applications?
Yes, the P6KE110AH is explicitly AEC-Q101 qualified, as confirmed in the ordering code documentation ("H" suffix denotes qualification). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD, making it suitable for under-hood and chassis-mounted automotive modules such as body control units, lighting drivers, and sensor interfaces. The P6KE110AH's −55°C to +175°C junction temperature range further supports this use case.
How does the P6KE110AH differ from the P6KE110A variant?
The P6KE110AH is identical to P6KE110A in electrical specifications (VBR: 105–116 V, VWM: 94.0 V, VC: 152 V) but adds AEC-Q101 qualification - a distinction clearly defined in TSC's ordering information where "H" indicates automotive qualification. The P6KE110A lacks this certification and is intended for commercial/industrial use only. Both share the same DO-204AC package and pinout, but only the P6KE110AH carries the automotive reliability validation.
What is the maximum reverse leakage current for the P6KE110AH at its stand-off voltage?
The P6KE110AH exhibits a maximum reverse leakage current (ID) of 1 μA when biased at its rated stand-off voltage (VWM) of 89.2 V, tested at 25°C ambient. This ultra-low leakage ensures minimal power loss in standby mode and prevents unintended loading of low-power sensor or microcontroller supply rails. The P6KE110AH maintains leakage below 5 μA up to 125°C, supporting stable operation in thermally demanding environments.
Can the P6KE110AH be used in bidirectional configurations?
No, the P6KE110AH is a unidirectional TVS diode, indicated by its "H" suffix and absence of "CA" or "C" designation in the part number. Bidirectional variants (e.g., P6KE110CA) are explicitly listed in the datasheet with symmetrical breakdown characteristics in both polarities. Using the P6KE110AH in reverse-biased AC applications would result in forward conduction and failure; always verify polarity marking (cathode band) and select CA-suffixed parts for bidirectional protection.
