Product details
Overview
P6KE110CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 110 V, clamps transients to ≤158 V at 3.9 A peak surge current, and delivers fast response (<1.0 ps from 0 V to VBR), low dynamic impedance, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE110CH datasheet, P6KE110CH pinout, P6KE110CH application, or P6KE110CH equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 89.2 V stand-off voltage, <1 µA reverse leakage above 10 V, and suitability for ESD/inductive switching protection in automotive body electronics, industrial PLC I/O modules, and LED driver input stages.
Technical Context
The P6KE110CH operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 99–121 V breakdown range (VBR) at 1 mA test current. Its clamping action limits transient energy to ≤158 V at 3.9 A (10/1000 µs waveform), enabling robust protection of downstream MOSFETs, controllers, and sensors against ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-5 surges.
Thermal performance is defined by a 175 °C maximum junction temperature and derating curve per Fig.2; steady-state power dissipation is 5 W at 75 °C with 9.5 mm lead length. The device uses pure tin-plated leads compliant with J-STD-002 and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 89.2 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail margin for 100 V systems. |
| VBR (min/max) | 99–121 V at 1 mA - Breakdown threshold range ensuring reliable turn-on during transients without premature conduction. |
| VC @ IPP | 158 V at 3.9 A (10/1000 µs) - Clamped voltage level protecting downstream ICs rated ≤150 V absolute max. |
| PPK | 600 W - Peak pulse power handling capability for automotive load dump and inductive switch-off events. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage preserves battery life and avoids false triggering in high-impedance sensing circuits. |
| TJ(max) | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal derating penalties. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, lighting modules, and ADAS sensor interfaces. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current path / low-side reference | Connected to ground or low-voltage return; enables clamping when cathode voltage rises above VWM. |
| Cathode (banded end) | Transient voltage sensing node | Connected to protected line (e.g., 12 V rail); avalanche conduction begins here upon overvoltage detection. |
Key Features
| Feature | Design Value |

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 | 600 W rating, same VBR range (99–121 V), but SMB package (surface-mount); lower IPP (3.8 A vs. 3.9 A). | Requires PCB rework for SMT layout; better suited for space-constrained designs where through-hole mounting is impractical. | Select SMBJ110A only if board real estate is limited and automated assembly is preferred over manual through-hole insertion. |
| 1.5KE110A | Same DO-15 package and VBR, but 1500 W rating (higher IPP = 13.3 A); larger junction capacitance (~100 pF vs. ~50 pF). | Better for extreme surge environments (e.g., railway traction power), but higher capacitance may degrade high-speed signal integrity. | Choose 1.5KE110A when surge threat level exceeds ISO 7637-2 Pulse 5a; avoid in high-frequency analog or CAN FD signal paths. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110CH offers optimal balance of AEC-Q101 compliance, through-hole manufacturability, and low-capacitance clamping-making it ideal for cost-sensitive, high-reliability automotive and industrial power rail protection where layout flexibility and qualification traceability are critical.

FAQ
What is the maximum clamping voltage of the P6KE110CH under standard surge conditions?
The P6KE110CH clamps to a maximum of 158 V when subjected to a 3.9 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components rated for ≤150 V absolute maximum voltage remain within safe operating limits during transient events.
Is the P6KE110CH suitable for bidirectional transient protection?
No, the P6KE110CH is a unidirectional TVS diode, indicated by the "H" suffix and cathode band marking. For bidirectional protection, select the P6KE110CA variant, which provides symmetrical clamping in both polarities and is designated for AC-line or data-line applications requiring dual-direction surge suppression.
Does the P6KE110CH meet automotive qualification standards?
Yes, the P6KE110CH is AEC-Q101 qualified, as confirmed in the ordering information section (Note 2: "H" means AEC-Q101 qualified). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making it suitable for under-hood and interior automotive modules.
What is the standoff voltage (VWM) of the P6KE110CH, and why does it matter?
The P6KE110CH has a standoff voltage (VWM) of 89.2 V, meaning it remains non-conductive up to this DC or RMS voltage level while leaking less than 1 µA. This margin ensures reliable operation on 80–90 V nominal systems (e.g., 24 V truck electronics with load dump) without false triggering or power loss.
How does the P6KE110CH compare to the P6KE110A in terms of electrical performance?
The P6KE110CH and P6KE110A share identical VBR (99–121 V), VC (158 V), and PPK (600 W) specifications, but the "H" suffix denotes AEC-Q101 qualification-absent in the standard P6KE110A. Both use DO-15 packaging, but only the P6KE110CH is certified for automotive production use with full PPAP support.
