Product details
Overview
P6KE100CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 100 V, stand-off voltage of 81.0 V, and clamping voltage of 144 V at 4.3 A peak surge current; it delivers fast sub-nanosecond response for ESD and lightning-induced transients in automotive power line protection.
For engineers reviewing the P6KE100CH datasheet, P6KE100CH pinout, P6KE100CH application, or P6KE100CH equivalent, this device is selected for high-reliability DC bus surge suppression where AEC-Q101 qualification, low leakage (<1 µA at 81 V), and DO-15 package compatibility are critical design requirements.
Technical Context
The P6KE100CH uses a silicon avalanche junction structure optimized for unidirectional clamping, with a maximum junction temperature of 175°C and thermal resistance (RθJA) consistent with DO-204AC mounting on 5×5 mm copper pads. Its 10/1000 µs waveform surge rating is derated linearly above 25°C ambient per Fig.2.
It exhibits a temperature coefficient of VBR of 0.106 %/°C and junction capacitance under 100 pF at 0 V bias (f = 1 MHz), making it suitable for moderate-speed signal-line protection without excessive capacitive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90.0 V / 110 V - defines guaranteed avalanche conduction onset window under 1 mA test current |
| VWM | 81.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPP | 144 V @ 4.3 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPK | 600 W - non-repetitive peak pulse power handling capability per standard waveform |
| IR @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ(max) | 175 °C - enables operation in under-hood automotive environments with sustained thermal stress |
| Response time | <1.0 ps - enables effective suppression of ESD events (IEC 61000-4-2) before circuit damage occurs |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking; meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance; terminals are pure tin plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to ground or low-side return in unidirectional clamp configuration |
| Cathode | Avalanche clamping node | Connected to protected line; conducts when transient exceeds VBR, shunting energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per stress test plan |
| 600 W 10/1000 µs surge rating | Withstands ISO 7637-2 Pulse 1 and Pulse 2b transients on 12 V/24 V vehicle power nets |
| Clamping voltage ≤144 V | Ensures protected 100 V-rated components remain below absolute maximum ratings during surge events |
| Leakage <1 µA at 81 V | Prevents measurable current draw in always-on battery-connected modules (e.g., CAN nodes, body controllers) |
| DO-15 mechanical compatibility | Direct drop-in replacement for legacy P6KE series and industry-standard TVS footprints in through-hole designs |
Applications
| Automotive Power Line Protection | Industrial DC Power Input |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients before they reach LDOs and microcontrollers. Use Value: Limits peak rail voltage to ≤144 V during ISO 7637-2 Pulse 5a (load dump), preventing latch-up or gate oxide rupture in downstream semiconductors. | Use Scenario: 48 V telecom or factory automation power supplies subject to inductive switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input stage, coordinated with upstream fuses and common-mode chokes. Use Value: Absorbs up to 600 W of surge energy within 1000 µs, enabling use of lower-cost input capacitors and eliminating need for active crowbar circuits. |
| LED Driver Surge Suppression | RS-485 Transceiver Port Protection |
Use Scenario: Constant-current LED drivers in street lighting subjected to lightning-induced surges on AC mains input. IC Role / Device Role / Timing Role: Secondary TVS on DC bus after bridge rectifier and bulk capacitor, protecting MOSFET switches and current-sense amplifiers. Use Value: Sub-nanosecond response captures fast-rising edge of induced surges, reducing peak stress on 100 V-rated FETs by >30% versus slower MOV-based solutions. | Use Scenario: Industrial RS-485 nodes installed in long cable runs across electrically noisy factory floors. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC rail and bidirectional pair on differential data lines (A/B), referenced to local ground. Use Value: Clamps EFT bursts (IEC 61000-4-4) to <150 V at transceiver pins, maintaining signal integrity and preventing false triggering or receiver saturation. |
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 | Surface-mount SMB package; 1.0 W steady-state rating vs. P6KE100CH's 5 W; same VBR range but lower IPP (4.1 A) | Preferred for space-constrained PCBs; not rated for AEC-Q101; requires re-layout | Select when board area is limited and automotive qualification is not required |
| 1.5KE100A | Same DO-15 package; higher 1500 W surge rating; VBR min/max tighter (95–105 V); higher VC (154 V) | Better for extreme surge environments (e.g., railway traction power); higher clamping increases risk to 100 V-rated loads | Select when surge threat level exceeds ISO 7637-2 and protected ICs tolerate ≥154 V transient exposure |
Compared with SMBJ100A and 1.5KE100A, the P6KE100CH offers AEC-Q101 validation and optimal clamping balance (144 V) for 100 V system rails-making it the preferred choice for automotive body electronics where qualification and precise voltage limiting are jointly required.

FAQ
What is the AEC-Q101 qualification status of P6KE100CH?
The P6KE100CH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in the P6KE SERIES datasheet Version P2203. This qualification covers temperature cycling, high-temperature operating life, and mechanical shock testing required for automotive under-hood and chassis applications. The P6KE100CH meets all stress test conditions defined in AEC-Q101 Rev D without derating or exception.
Does P6KE100CH have bidirectional capability?
No, P6KE100CH is a unidirectional TVS diode, as indicated by its "CH" suffix and the presence of a cathode band marking. It clamps only in reverse bias (cathode positive) and conducts forward like a standard diode. For bidirectional protection, the equivalent part is P6KE100CA; the P6KE100CH must be used with correct polarity orientation in circuit layout.
What is the maximum peak surge current rating for P6KE100CH?
The P6KE100CH has a maximum peak surge current (IPP) of 4.3 A under the standardized 10/1000 µs double-exponential waveform. This value is derived from its 600 W peak pulse power rating and 144 V clamping voltage (IPP = PPK/VC). Derating applies above 25°C ambient per the pulse derating curve in the datasheet.
How does the leakage current of P6KE100CH compare to similar TVS diodes?
At its 81.0 V stand-off voltage, the P6KE100CH specifies maximum reverse leakage current of 1 µA - matching industry benchmarks for 100 V-class DO-15 TVS devices. This low leakage supports battery-backed systems (e.g., automotive body modules) where quiescent current budgets are tight; it is 10× lower than many legacy 1.5KE-series parts at equivalent VWM.
Can P6KE100CH replace P6KE100A in existing designs?
Yes, P6KE100CH is a direct functional and mechanical replacement for P6KE100A: both share identical DO-15 packaging, pinout, VBR (95–105 V), VWM (85.5 V), and VC (137 V). The key difference is AEC-Q101 qualification - P6KE100CH adds automotive reliability validation while maintaining full electrical and layout compatibility with P6KE100A.
