Product details
Overview
P6KE100C 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 (VBR min/max: 90–110V), 81.0V stand-off voltage (VWM), clamps to ≤144V at 4.3A peak surge current, and delivers sub-nanosecond response time (<1.0ps from 0V to VBR). It is used in automotive body electronics to protect LIN bus transceivers against load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE100C datasheet, P6KE100C pinout, P6KE100C application, or P6KE100C equivalent, this page provides verified electrical parameters, DO-15 package mechanical data, clamping performance under 10/1000μs surges, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade designs.
Technical Context
The P6KE100C operates as a unidirectional avalanche diode with a single-die DO-204AC (DO-15) construction. Its junction exhibits low dynamic impedance and a temperature coefficient of VBR at 0.106%/°C, enabling stable clamping across –55°C to +175°C operating range. It meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
It sustains non-repetitive 600W peak pulse power per 10/1000μs waveform, with steady-state power dissipation rated at 5W at TA = 75°C on 5×5 mm copper pads. Reverse leakage remains ≤1 μA at 81.0V (VWM), and it supports 100A forward surge current (IFSM, 8.3ms half-sine) - applicable only to unidirectional variants like P6KE100C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90 V / 110 V - ensures reliable avalanche conduction onset within ±10% of nominal 100V rating |
| VWM | 81.0 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPPM | 144 V at 4.3 A - clamping voltage during full 600W surge; defines worst-case protected circuit stress |
| PPK | 600 W - peak pulse power handling per 10/1000μs waveform; validates compliance with IEC 61000-4-5 Level 4 |
| IR @ VWM | ≤1 μA - ultra-low leakage preserves battery-powered system standby current and signal integrity |
| TJ max | +175 °C - enables placement near heat-generating components (e.g., power MOSFETs, motor drivers) |
| Response time | <1.0 ps - enables suppression of ESD events (IEC 61000-4-2) before IC damage occurs |

Applications
| Automotive LIN Bus Protection | Industrial PLC Digital Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Standoff protector on input terminal block, shunting induced transients before they reach optocoupler input stage. Use Value: Withstands ≥4.3A surge current while maintaining <1μA leakage at 24V nominal, ensuring no false triggering during normal operation. |
| DC Power Rail Surge Suppression | LED Driver Output Protection |
|

Use Scenario: Output-side TVS on constant-current LED drivers in streetlight systems vulnerable to induced surges on long cable runs. IC Role / Device Role / Timing Role: Unidirectional shunt protector on driver output terminals, absorbing inductive kickback from open-circuit LED strings. Use Value: Maintains 81.0V standoff to avoid conduction during normal 36–42V LED string operation, yet triggers reliably at 90V+ transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same 100V VBR range but SMC package (higher thermal mass); 600W rating at 10/1000μs; lower IR (≤1 μA) | Preferred where PCB space allows surface-mount and higher thermal endurance is needed (e.g., industrial power supplies) | Select SMBJ100A for automated assembly and improved thermal performance; P6KE100C remains optimal for through-hole legacy designs and cost-sensitive automotive modules |
| P6KE100CH | AEC-Q101 qualified version of P6KE100C; identical electrical specs; marked with 'H' suffix and green compound | Required for new automotive ECUs targeting OEM qualification; not necessary for non-automotive or non-safety-critical use | Choose P6KE100CH when AEC-Q101 compliance is mandated; otherwise P6KE100C offers identical protection at lower cost |
Compared with SMBJ100A and P6KE100CH, the P6KE100C provides identical clamping performance and surge rating in a lower-cost DO-15 through-hole package, making it ideal for cost-driven, non-automotive applications where AEC-Q101 is not required and manual or wave soldering is used.

FAQ
What is the polarity configuration of P6KE100C?
The P6KE100C is a unidirectional TVS diode, configured with a cathode band marking indicating the cathode terminal. It conducts in reverse bias during overvoltage events and blocks current up to 81.0V in the forward direction. This polarity is essential for correct placement in DC line protection circuits where the protected node connects to the cathode and ground to the anode.
Does P6KE100C meet AEC-Q101 reliability standards?
The base P6KE100C is not AEC-Q101 qualified; however, its variant P6KE100CH is fully AEC-Q101 certified for automotive applications. The 'H' suffix denotes qualification across temperature cycling, humidity, and mechanical stress tests per AEC-Q101 Rev D. For non-automotive use, P6KE100C delivers identical electrical performance without the qualification overhead.
What is the maximum clamping voltage of P6KE100C under surge conditions?
The maximum clamping voltage (VC) of P6KE100C is 144 V, measured at its peak pulse current (IPPM) of 4.3 A under the standard 10/1000μs waveform. This value represents the highest voltage imposed on the protected circuit during a full-rated 600W transient event and is critical for verifying compatibility with downstream component voltage ratings.
Can P6KE100C be used in bidirectional configurations?
No - P6KE100C is strictly unidirectional. For bidirectional protection, the 'CA' suffix variant (e.g., P6KE100CA) must be selected. Bidirectional types feature symmetrical breakdown in both polarities and lack cathode band marking. Using P6KE100C in reverse-biased AC applications risks catastrophic failure due to forward conduction during negative half-cycles.
What is the junction temperature range for reliable operation of P6KE100C?
P6KE100C is rated for junction temperatures from –55°C to +175°C, enabling deployment in under-hood automotive environments and industrial enclosures with minimal heatsinking. Its thermal derating curve (Fig.2 in datasheet) shows 100% power capability at 25°C ambient, linearly decreasing to ~50% at 100°C ambient, supporting robust operation in thermally demanding layouts.
