Product details
Overview
P6KE7.5C from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 7.5V, clamps transients to ≤11.7V at 53A peak surge current, and delivers fast response (<5.0ns) with low dynamic impedance - deployed in automotive lighting control modules and industrial sensor interfaces.
For engineers reviewing the P6KE7.5C datasheet, P6KE7.5C pinout, P6KE7.5C application, or P6KE7.5C equivalent, key selection criteria include its bidirectional DO-15 package, 6.75–8.25V VBR range at 10mA, 6.05V stand-off voltage, <1μA leakage above 10V, and UL 94V-0 flammability compliance for high-reliability PCB-level surge immunity.
Technical Context
The P6KE7.5C is a silicon avalanche diode configured as a bidirectional TVS, operating symmetrically in both polarities without polarity dependence. Its junction structure enables sub-5ns response to EFT and lightning-induced transients while maintaining stable clamping under repetitive 10/1000μs surges up to 600W.
It complies with ANSI/IEEE C62.35 for transient suppression and meets AEC-Q101 qualification (per P6KE7.5C ordering code suffix "C"), supporting operation across –55°C to +175°C junction temperature with <0.061%/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75V / 8.25V at 10mA test current - defines reliable conduction onset window for bidirectional clamping |
| VWM | 6.05V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPP | 11.7V at 53A peak pulse - actual clamping voltage limiting downstream circuit stress during surge |
| PPK | 600W - peak non-repetitive surge power handling per 10/1000μs waveform |
| IR @ VWM | <1μA - ensures negligible standby power loss and minimal interference in low-power sensing circuits |
| TJ max | +175°C - enables placement near heat-generating components in engine control units or power converters |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, RoHS/halogen-free compliant |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional variants; P6KE7.5C is bidirectional and has no polarity marking - terminals are symmetrical and interchangeable.

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 SMAJ7.5CA | Same DO-214AC package; 7.5V nominal, 12.5V clamping at 49.2A; slightly higher VC and lower IPP | Preferred where board space constraints favor SMD over axial DO-15 | Select when surface-mount assembly is required and 0.8V higher clamping is acceptable |
| ON Semiconductor 1.5KE7.5C | Same bidirectional DO-201AE package; identical VBR (6.75–8.25V), but 1.5kW rating and larger footprint | Suitable for higher-energy surge environments (e.g., telecom power feeds) | Choose for applications needing >600W margin or legacy 1.5KE footprint compatibility |
Compared with P6KE7.5C, SMAJ7.5CA offers SMD convenience at the cost of higher clamping voltage, while 1.5KE7.5C provides greater surge headroom in a larger axial package - P6KE7.5C balances compact DO-15 size, AEC-Q101 qualification, and precise 11.7V clamping for cost-sensitive automotive and industrial designs.

FAQ
What is the exact breakdown voltage range for P6KE7.5C?
The P6KE7.5C has a guaranteed breakdown voltage range of 6.75V to 8.25V at 10mA test current (IT), measured per ANSI/IEEE C62.35. This bidirectional specification applies equally in both directions, confirming symmetric clamping behavior critical for AC-coupled or floating signal protection in designs using P6KE7.5C.
Is P6KE7.5C AEC-Q101 qualified?
Yes, P6KE7.5C is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's ordering code suffix "C" and documented in the P6KE Series datasheet Version P2203. This qualification covers temperature cycling, mechanical shock, humidity testing, and high-temperature operating life, validating P6KE7.5C for under-hood automotive use including lighting control and body electronics.
What is the maximum clamping voltage of P6KE7.5C and at what current?
The maximum clamping voltage (VC) of P6KE7.5C is 11.7V at a peak pulse current (IPP) of 53A, tested with the standard 10/1000μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case surge events, making it a key parameter for ensuring safe operation of ICs protected by P6KE7.5C.
Does P6KE7.5C have polarity markings on the package?
No, P6KE7.5C does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., P6KE7.5), the P6KE7.5C uses a symmetrical junction structure - both leads are functionally identical, and orientation during PCB assembly has no electrical impact. The DO-15 package contains no cathode band for this part.
What is the leakage current specification for P6KE7.5C at its stand-off voltage?
P6KE7.5C exhibits a maximum reverse leakage current (IR) of less than 1μA when biased at its rated stand-off voltage (VWM) of 6.05V. This ultra-low leakage ensures minimal power loss and signal distortion in always-on sensor interfaces or battery-powered systems where P6KE7.5C is deployed for permanent overvoltage protection.
