Product details
Overview
P6KE75A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 75 V, clamps transients to ≤103 V at 6.1 A peak surge current, and maintains <1 μA reverse leakage at its 64.1 V stand-off voltage - enabling robust ESD and lightning surge protection in automotive body electronics and industrial control I/O modules.
For engineers reviewing the P6KE75A datasheet, P6KE75A pinout, P6KE75A application, or P6KE75A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 103 V clamping voltage at 6.1 A, 175 °C maximum junction temperature, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE75A operates as a silicon avalanche diode with fast response time (<1.0 ps from 0 V to VBR) and low dynamic impedance, enabling effective suppression of fast-rising transients such as EFT (electrical fast transients) and ISO 7637-2 load dump spikes. Its unidirectional configuration provides asymmetric clamping - conducting only during reverse overvoltage events while blocking forward conduction beyond its rated forward surge capability.
Thermal performance is defined by a 175 °C maximum junction temperature and derated pulse power above 25 °C ambient per Fig.2; steady-state power dissipation is limited to 5 W at 75 °C on 5×5 mm copper pads. The device meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance, supporting long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA test current - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 64.1 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 103 V at 6.1 A peak pulse current - actual clamped voltage seen by protected circuit during 10/1000 µs surge |
| PPK | 600 W - non-repetitive surge power handling per standard 10/1000 µs 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 and industrial environments without thermal shutdown |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional polarity. Leads are pure tin plated and solderable per J-STD-002; case meets UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events up to 100 A (8.3 ms half-sine) |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanches into conduction when reverse voltage exceeds 71.3–78.8 V, shunting surge current to anode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics per stress test requirements |
| 600 W surge capability | Withstands ISO 7637-2 Pulse 1 (−150 V/2 Ω) and Pulse 2a (−100 V/50 Ω) without degradation |
| Clamping voltage ≤103 V | Ensures downstream 75 V-rated components remain within safe operating area during 6.1 A transient events |
| Leakage <1 µA at 64.1 V | Prevents measurable power drain in always-on systems such as CAN bus nodes or battery-backed sensors |
| Fast response <1.0 ps | Responds before most microsecond-scale transients fully develop, minimizing voltage overshoot on protected ICs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

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 SMAJ75A | Same DO-214AC (SMA) package; 75 V nominal, 103 V clamping at 6.1 A; slightly higher leakage (≤5 µA @ 64.1 V) | Surface-mount alternative requiring PCB redesign; better thermal dissipation in high-density layouts | Select when board space is constrained and reflow assembly is preferred over through-hole mounting. |
| ON Semiconductor 1.5KE75A | Same DO-201AD (DO-27) axial package; identical VBR, VC, and PPK; AEC-Q101 not specified in standard datasheet | Drop-in mechanical replacement but requires validation for automotive use due to missing AEC-Q101 certification | Select for cost-sensitive industrial applications where automotive qualification is not required. |
Compared with SMAJ75A and 1.5KE75A, the P6KE75A offers verified AEC-Q101 qualification in the legacy DO-15 through-hole package - making it optimal for automotive service replacements and legacy industrial designs where board-level reliability and mechanical robustness are prioritized over footprint size.

FAQ
What is the clamping voltage of the P6KE75A under standard surge conditions?
The P6KE75A clamps to a maximum of 103 V when subjected to a 10/1000 µs surge waveform at 6.1 A peak current. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on the protected circuit during transient events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the P6KE75A suitable for automotive applications?
Yes, the P6KE75A is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. Its 175 °C maximum junction temperature, robust surge capability, and validated reliability testing meet stringent automotive environmental and lifetime requirements.
How does the P6KE75A differ from the P6KE75 (non-A) variant?
The P6KE75A has tighter breakdown voltage tolerance (71.3–78.8 V vs. 67.5–82.5 V for P6KE75) and lower clamping voltage (103 V vs. 108 V), reflecting improved process control and enhanced protection margin. Both share the same DO-204AC package and 600 W surge rating, but the 'A' suffix denotes enhanced parametric consistency.
What is the reverse leakage current specification for the P6KE75A?
The P6KE75A exhibits ≤1 µA maximum reverse leakage current at its 64.1 V stand-off voltage (VWM). This ultra-low leakage ensures minimal power loss in always-on systems and preserves signal integrity in high-impedance sensor interfaces - a key advantage over alternatives with higher leakage thresholds.
Can the P6KE75A be used in bidirectional configurations?
No - the P6KE75A is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Taiwan Semiconductor offers the P6KE75CA variant (with 'CA' suffix), which provides symmetrical clamping in both polarities and is electrically characterized in both directions per datasheet Section "Devices for Bipolar Applications".
