Product details
Overview
P4KE110C from Taiwan Semiconductor is a unidirectional 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 at 1mA), 89.2V working stand-off voltage (VWM), clamps transients to ≤158V at 2.6A peak pulse current, and delivers 400W surge capability per 10/1000μs waveform - deployed in automotive body control modules, industrial PLC I/O protection, and telecom power supply inputs.
For engineers reviewing the P4KE110C datasheet, P4KE110C pinout, P4KE110C application, or P4KE110C equivalent, key selection criteria include verified unidirectional clamping performance, DO-41 package thermal derating behavior, junction temperature limits up to +175°C, and compliance with AEC-Q101 stress testing for automotive-grade reliability.
Technical Context
The P4KE110C operates as a silicon avalanche diode with fast response time (<1.0ps from 0V to VBR), low dynamic impedance, and tightly controlled breakdown voltage tolerance (±5% for "C" suffix). Its unidirectional polarity enables asymmetric clamping-forward conduction only during positive transients-making it suitable for DC-biased circuits where reverse leakage must remain minimal (<1μA at 89.2V).
Thermal design relies on its DO-204AL (DO-41) package with pure tin-plated leads solderable per J-STD-002, rated for 1W steady-state dissipation at 75°C lead temperature and 400W non-repetitive peak pulse power. Junction temperature range spans −55°C to +175°C, supporting operation in under-hood automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 89.2 V - Maximum continuous reverse voltage before significant leakage; defines safe operating DC bias level |
| VBR @ IT=1mA | 99–121 V - Breakdown voltage range at 1mA test current; determines clamping onset threshold |
| VC @ IPPM | 158 V - Clamped voltage at 2.6A peak pulse; sets worst-case transient voltage seen by protected circuit |
| PPK | 400 W - Peak pulse power handling at 10/1000μs waveform; defines single-event surge robustness |
| ID @ VWM | <1 μA - Reverse leakage at working voltage; ensures negligible standby power loss and signal integrity |
| TJ max | +175 °C - Maximum junction temperature; supports high-ambient deployments without thermal shutdown |
| Package | DO-204AL (DO-41) - Industry-standard axial-leaded package with UL 94V-0 molding compound and JESD201 Class 2 whisker resistance |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, cylindrical glass-passivated body, cathode indicated by band marking. Leads are pure tin-plated, compliant with J-STD-002 solderability requirements.

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 | Surface-mount SMB package; 110V bidirectional; 600W peak power; higher clamping voltage (187V) | Used where board space is constrained and bidirectional protection is required (e.g., data lines) | Select SMBJ110A only if SMT layout and bidirectional clamping are mandatory; P4KE110C offers lower clamping and through-hole mechanical robustness |
| 1N6277A | Same DO-41 package; 110V unidirectional; 400W rating; slightly higher VWM (90V) and VC (160V) | Legacy industrial design with identical mounting and thermal profile | 1N6277A is functionally interchangeable with minor parameter shifts; verify leakage & clamping margin in final design |
Compared with SMBJ110A and 1N6277A, the P4KE110C provides tighter VBR tolerance (±5%), lower clamping voltage (158V vs. 160V/187V), and AEC-Q101 qualification path - making it preferred for new automotive and high-reliability industrial designs requiring proven axial-leaded surge resilience.

FAQ
What is the polarity configuration of the P4KE110C?
The P4KE110C is a unidirectional TVS diode with cathode-band marking indicating the cathode terminal. It conducts only when the cathode is positively biased relative to the anode, making it ideal for DC power rail protection where reverse conduction must be blocked. This polarity is confirmed in the mechanical data section and marking diagram of the official P4KE series datasheet (Version N2104).
Does the P4KE110C meet AEC-Q101 qualification?
The base P4KE110C is not AEC-Q101 qualified; however, the variant P4KE110CH (with 'H' suffix) is explicitly listed as AEC-Q101 qualified in the ordering information table. Engineers requiring automotive-grade reliability must specify P4KE110CH - the 'H' denotes full stress-test compliance per AEC-Q101 Rev D, including HTGB, AC-H3TRB, and temperature cycling.
What is the maximum clamping voltage of the P4KE110C at rated peak pulse current?
The maximum clamping voltage (VC) of the P4KE110C is 158 V at 2.6 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential waveform. This value is specified in the "Maximum clamping voltage VC@IPPM" column of the electrical characteristics table for P4KE110 in the official datasheet (Page 3, Version N2104).
How does the P4KE110C compare to the P4KE110A in terms of voltage tolerance?
The P4KE110C has a breakdown voltage range of 99–121 V (±10%) at 1 mA, while the P4KE110A offers tighter 105–116 V (±5%) tolerance. The 'A' suffix denotes ±5% VBR tolerance; 'C' denotes ±10%. Both share identical VWM (89.2 V), VC (158 V), and power rating (400 W), but P4KE110A is preferred where precise clamping threshold is critical.
Can the P4KE110C be used in bidirectional signal line protection?
No - the P4KE110C is strictly unidirectional and unsuitable for bidirectional signal lines such as RS-485 or USB. For bidirectional protection, select the P4KE110CA variant ('CA' suffix), which is explicitly designated for bipolar applications and exhibits symmetrical clamping in both directions per the datasheet's "Devices for bipolar applications" note.
