Product details
Overview
P6KE7V5CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in power rails and signal lines. It features a nominal breakdown voltage of 7.5 V, clamps transients to ≤12.1 V at 500 A peak surge current, exhibits <1 μA leakage at 6.4 V stand-off voltage, and uses DO-204AC (DO-15) package for through-hole mounting in automotive and industrial control systems.
For engineers reviewing the P6KE7V5CA datasheet, P6KE7V5CA pinout, P6KE7V5CA application, or P6KE7V5CA equivalent, key selection criteria include bidirectional clamping performance under 10/1000 µs surges, low dynamic impedance for fast response (<5 ns), AEC-Q101 qualification status, RoHS/halogen-free compliance, and compatibility with JEDEC-standard DO-15 footprint and soldering processes.
Technical Context
The P6KE7V5CA operates as a silicon avalanche diode configured in bidirectional symmetry, enabling identical clamping behavior in both polarities without external polarity management. Its junction structure delivers low dynamic impedance (enabling rapid voltage clamping) and a temperature coefficient of VBR at 0.061 %/°C - critical for stable protection across automotive ambient ranges.
It complies with ANSI/IEEE C62.35 for transient suppression, supports unidirectional forward surge up to 100 A (8.3 ms half-sine), and is rated for continuous operation from −55 °C to +175 °C junction temperature - validated per JESD201 Class 2 whisker testing and UL 94V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 7.5 V - defines primary clamping threshold for bidirectional surge events |
| Breakdown Voltage (VBR) | 7.13–7.88 V @ 10 mA - ensures reliable avalanche initiation within tight tolerance band |

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 (SMA) package; 600 W rating; VBR = 7.22–8.02 V; VC = 12.5 V @ 48.8 A | Lower IPP (48.8 A vs. 500 A) - suited for lower-energy signal-line protection only | Select when space-constrained SMT layout is required and surge energy is ≤100 W |
| Vishay 1.5KE7.5CA | Higher PPK = 1500 W; DO-201AD package; VBR = 6.4–7.9 V; VC = 12.0 V @ 125 A | Higher surge capacity but larger footprint - requires PCB real estate and thermal pad design | Select when legacy 1.5 kW surge immunity is mandated and DO-15 footprint is not constrained |
Compared with Littelfuse SMAJ7.5CA and Vishay 1.5KE7.5CA, the P6KE7V5CA offers optimal balance of DO-15 through-hole compatibility, 500 A surge handling, and AEC-Q101 qualification - making it preferred for cost-sensitive, high-reliability automotive and industrial power rail protection where leaded assembly is maintained.

FAQ
What is the clamping voltage of the P6KE7V5CA under maximum surge conditions?
The P6KE7V5CA clamps to a maximum of 12.1 V when subjected to its rated peak pulse current of 500 A using the 10/1000 µs waveform. This value is measured at the device terminals under standardized test conditions and represents the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream 5 V or 3.3 V ICs remain within absolute maximum ratings.
Is the P6KE7V5CA suitable for automotive applications?
Yes, the P6KE7V5CA is AEC-Q101 qualified when ordered with the "H" suffix (e.g., P6KE7V5CAH), confirming compliance with automotive reliability stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock. The base P6KE7V5CA part meets all electrical and thermal specifications required for under-hood and body-control module deployments.
How does the bidirectional configuration of the P6KE7V5CA affect PCB layout?
The P6KE7V5CA has no polarity marking and functions identically in either orientation, eliminating orientation-dependent placement errors during assembly. Unlike unidirectional TVS diodes, it requires no cathode band alignment - simplifying layout, reducing BOM complexity, and enabling direct replacement in existing bidirectional protection circuits without redesign.
What is the maximum steady-state power dissipation for the P6KE7V5CA at 75°C ambient?
The P6KE7V5CA dissipates up to 5 W continuously at TA = 75°C when mounted on 5 × 5 mm copper pads per terminal, per JEDEC standards. This derated power rating ensures safe thermal operation in enclosed enclosures and high-density boards - exceeding typical standby leakage power and supporting long-term reliability in industrial control cabinets.
Does the P6KE7V5CA meet halogen-free and RoHS requirements?
Yes, the P6KE7V5CA uses halogen-free molding compound compliant with IEC 61249-2-21 and is fully RoHS-compliant per EU Directive 2011/65/EU. Lead finish is pure tin, and all materials are documented in TSC's substance declaration - satisfying environmental compliance requirements for global OEMs and Tier 1 suppliers.
