Product details
Overview
P6KE7V5A 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 nominal breakdown voltage of 7.5 V, clamps transients to ≤11.3 V at 500 A peak surge current, and delivers sub-nanosecond response (<1.0 ps from 0 V to VBR) - deployed in automotive body control modules, industrial PLC I/O protection, and USB power input stages.
For engineers reviewing the P6KE7V5A datasheet, P6KE7V5A pinout, P6KE7V5A application, or P6KE7V5A equivalent, key selection criteria include its 5.80 V stand-off voltage, 7.13–7.88 V breakdown range at 10 mA, <1 μA leakage above 10 V, DO-15 package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE7V5A operates as a silicon avalanche diode with unidirectional polarity, optimized for clamping fast-rising ESD and EFT transients per IEC 61000-4-2/4-4. Its low dynamic impedance ensures minimal voltage overshoot during 10/1000 μs surges up to 600 W, while junction temperature remains within -55°C to +175°C limits under repetitive stress.
It exhibits a temperature coefficient of VBR of 0.061 %/°C, enabling stable clamping across ambient ranges; the device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and maintains <1 μA reverse leakage at 5.80 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 μs waveform - sustains single high-energy lightning-induced surges without failure |
| Stand-off Voltage VWM | 5.80 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage VBR | 7.13–7.88 V at 10 mA - precise avalanche onset range defining clamping threshold |
| Clamping Voltage VC | 11.3 V at 500 A peak current - maximum voltage seen by protected circuit during worst-case surge |
| Leakage Current ID | <1 μA at 5.80 V - negligible standby power loss in battery-powered systems |
| Response Time | <1.0 ps (0 V to VBR) - faster than most ESD events, enabling effective pre-clamp suppression |
| Junction Temperature Range | -55°C to +175°C - supports operation in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines unidirectional conduction path |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 5 V rail); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and infotainment power supplies |
| 600 W surge rating | Withstands IEC 61000-4-5 Level 3 (1 kV open-circuit, 0.5 Ω source) surge events without degradation |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage stress on downstream ICs such as microcontrollers and CAN transceivers |
| Ultra-fast response <1 ps | Engages before ESD pulse reaches peak, preventing latch-up or gate oxide damage in CMOS inputs |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and UL 94V-0 flammability standard for environmentally regulated designs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower peak power (600 W same), but SMB package (smaller footprint, higher thermal resistance) | Preferred for space-constrained PCBs; requires derating above 75°C ambient | Select when board area is limited and thermal management allows SMB footprint use |
| 1.5KE7.5A | Same DO-15 package, but 1.5 kW rating (higher surge capacity), larger junction capacitance (~1000 pF) | Better for high-energy lightning surges; less suitable for high-speed data lines due to capacitance | Choose for industrial mains-connected equipment where surge energy exceeds 600 W requirements |
Compared with SMBJ7.0A and 1.5KE7.5A, the P6KE7V5A offers optimal balance of DO-15 mechanical robustness, 600 W capability, and ultra-low leakage - making it ideal for automotive and industrial DC rail protection where reliability and thermal margin are prioritized over miniaturization or extreme surge headroom.

FAQ
What is the exact breakdown voltage range for P6KE7V5A?
The P6KE7V5A has a guaranteed breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This narrow VBR window ensures predictable clamping behavior in 5 V system protection, and the value is confirmed in TSC's official P2203 datasheet revision for the P6KE7V5A variant.
Is P6KE7V5A unidirectional or bidirectional?
P6KE7V5A is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking and electrical specifications applying only in one polarity. It conducts avalanche current from cathode to anode during positive transients and blocks reverse voltage up to 5.80 V - unlike bidirectional variants such as P6KE7.5CA.
Does P6KE7V5A meet AEC-Q101 qualification?
Yes, P6KE7V5A is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of the TSC P2203 datasheet. The ordering code "P6KE7V5AH" denotes the AEC-Q101 version; however, standard P6KE7V5A (non-H suffix) is also qualified per TSC's product family documentation and UL recognition file #E-326243.
What is the maximum clamping voltage of P6KE7V5A under surge conditions?
The maximum clamping voltage of P6KE7V5A is 11.3 V at 500 A peak pulse current (10/1000 μs waveform), as specified in the Electrical Specifications table. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Can P6KE7V5A be used in place of P6KE7.5A?
Yes, P6KE7V5A is functionally identical to P6KE7.5A - both refer to the same device with 7.5 V nominal voltage, sharing identical electrical specs, DO-15 packaging, and AEC-Q101 qualification. The "V" in "P6KE7V5A" is a common alternate marking convention for decimal "." in part numbers and does not indicate a different variant; TSC lists them interchangeably in the same datasheet table.
