Product details
Overview
P6KE100A 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 100V nominal breakdown voltage (95–105V VBR), 85.5V stand-off voltage (VWM), 137V maximum clamping voltage at 4.5A peak surge current, and operates across –55°C to +175°C junction temperature range. It is used in automotive power supply input stages to absorb load-dump and ISO 7637-2 pulse 5a transients.
For engineers reviewing the P6KE100A datasheet, P6KE100A pinout, P6KE100A application, or P6KE100A equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA at 85.5V), AEC-Q101 qualification status, DO-15 mechanical compatibility, and thermal derating behavior above 25°C ambient.
Technical Context
The P6KE100A employs a planar passivated silicon junction optimized for fast response (<1.0ps rise from 0V to VBR) and low dynamic impedance to minimize voltage overshoot during ESD or lightning-induced surges. Its unidirectional configuration provides asymmetric conduction-low forward voltage drop in normal operation and rapid avalanche clamping during reverse overvoltage events.
It is rated for non-repetitive 600W peak pulse power per 10/1000μs waveform, with thermal derating starting at 25°C and full power limited to TA ≤ 75°C. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements, confirming suitability for high-reliability PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin below clamping threshold |
| VBR (min/max) | 95 V / 105 V - Breakdown occurs within this band at 1 mA test current; ensures consistent clamping onset across production lot |
| VC @ IPP | 137 V at 4.5 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ100A | Same DO-214AC package; 100V VBR (95–105V), 137V VC @ 4.5A, but rated for 400W (not 600W) peak power | Lower surge rating limits use in high-energy automotive load-dump scenarios; suitable for lower-energy industrial I/O | Select when footprint compatibility is critical but 600W surge headroom is not required |
| ON Semiconductor 1.5KE100A | Same 100V rating and DO-204AC package; identical 137V VC, but higher 1.5kW peak power rating and larger thermal mass | Over-specified for most P6KE100A use cases; requires more board space and higher cost | Choose only if future-proofing for higher-energy transients or extended thermal cycling is mandated |
Compared with SMAJ100A and 1.5KE100A, the P6KE100A delivers optimal balance of 600W surge capacity, DO-15 form factor, AEC-Q101 qualification, and cost-making it the preferred choice for automotive and industrial applications where reliability and standardization are prioritized over extreme power headroom or ultra-compact packaging.

FAQ
What is the clamping voltage of the P6KE100A under a standard 10/1000μs surge?
The P6KE100A has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.5 A using the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 137 V during such transients. The P6KE100A maintains this clamping performance across its full operating temperature range.
Is the P6KE100A AEC-Q101 qualified?
Yes, the P6KE100A is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor documentation (Version P2203). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, making the P6KE100A suitable for automotive powertrain and chassis applications. The "H" suffix denotes AEC-Q101 compliance, and P6KE100A falls within the qualified voltage range.
What is the difference between P6KE100 and P6KE100A?
The P6KE100A offers tighter breakdown voltage tolerance (95–105 V) compared to the P6KE100 (90–110 V), resulting in more predictable clamping onset and reduced unit-to-unit variation. Both share identical package (DO-15), power rating (600W), and thermal specs, but the "A" suffix indicates enhanced VBR binning-critical for designs requiring precise overvoltage thresholds. The P6KE100A also exhibits slightly lower leakage and improved temperature coefficient consistency.
Can the P6KE100A be used in bidirectional configurations?
No, the P6KE100A is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical specifications-including breakdown voltage, clamping, and leakage-are defined only for reverse-biased (cathode-positive) surge events. For bidirectional protection, Taiwan Semiconductor specifies CA-suffixed parts (e.g., P6KE100CA); using P6KE100A in AC or bipolar signal paths may result in forward conduction failure or inadequate clamping.
What is the maximum junction temperature rating for the P6KE100A?
The P6KE100A has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings in the datasheet. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating of peak pulse power begins above 25°C ambient, with full 600W capability maintained only up to TA = 75°C when mounted on specified 5×5 mm copper pads.
