Product details
Overview
P6KE7V5CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 6.40V reverse standoff voltage (VRWM), 7.13V minimum breakdown voltage (VBR), 11.3V maximum clamping voltage (VC) at 53A peak pulse current, and DO-15 package with glass-passivated junction - used in automotive body control modules to suppress load-dump and inductive switching transients.
For engineers reviewing the P6KE7V5CA-T datasheet, P6KE7V5CA-T pinout, P6KE7V5CA-T application, or P6KE7V5CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under ISO 7637-2 Pulse 1/2a/5a waveforms, unidirectional vs. bidirectional polarity requirement, and thermal derating behavior at elevated ambient temperatures.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated die construction ensures stable leakage performance and robust surge endurance under repeated 8.3ms half-sine surges up to 100A IFSM.
The device complies with JEDEC standards for transient suppression and exhibits fast response time (<1 ns) to ESD and lightning-induced transients. Thermal resistance from junction to ambient is 75°C/W, requiring careful PCB copper land design (40 mm² recommended) to sustain steady-state dissipation up to 5.0W at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms non-repetitive waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage | 6.40V (maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage) |
| Breakdown Voltage | 7.13V min @ 10mA (voltage at which device enters avalanche conduction; confirms turn-on threshold margin above VRWM) |
| Clamping Voltage | 11.3V max @ 53A IPP (maximum voltage seen by downstream circuit during worst-case surge; determines protection level for 5V/3.3V logic) |
| Peak Pulse Current | 53.0A (maximum single-event surge current it can safely shunt without degradation) |
| Package | DO-15 (axial-leaded plastic package rated UL 94V-0; supports manual or wave soldering with 0.4g mass) |
| Operating Temperature | -55°C to +175°C (enables use in under-hood automotive environments and industrial motor drives) |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body with glass-passivated silicon die. Cathode band marking is omitted on bidirectional variants; part number only is laser-marked. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity designation - either lead functions identically as input/output terminal for transient clamping in either direction |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports high-energy transients per ISO 7637-2 Pulse 5a (load dump) without failure |
| Glass-passivated die | Ensures stable leakage current (<500µA @ VRWM) and long-term reliability under thermal cycling |
| Bidirectional configuration | Enables protection of AC signals, differential buses (e.g., RS-485), and floating power domains without external polarity management |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with lead-free reflow profiles |
Applications
| Automotive Body Control Module | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protects microcontroller I/O and CAN transceiver power pins against load-dump events (ISO 16750-2) and alternator ripple in vehicle door modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between VBAT and GND, responding within <1 ns to clamp transients above 11.3V. Use Value: Prevents latch-up or permanent damage to 5V logic circuits exposed to 35V/100ms load-dump surges. | Use Scenario: Shields 24V digital input terminals of programmable logic controllers from field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on dry-contact inputs, mounted directly at connector entry point. Use Value: Limits transient voltage to ≤11.3V during 1kV/500Ω ring-wave tests (IEC 61000-4-5), preserving optocoupler isolation integrity. |
| RS-485 Transceiver Protection | DC Power Rail Surge Suppression |
Use Scenario: Safeguards half-duplex RS-485 transceivers (e.g., MAX13487) in building automation networks exposed to EFT and lightning-induced common-mode noise. IC Role / Device Role / Timing Role: Bidirectional TVS connected line-to-line (A–B) and line-to-ground to suppress differential and common-mode transients. Use Value: Maintains signal integrity by clamping differential surges to <11.3V while adding <1pF capacitance - negligible impact on 10 Mbps data rates. | Use Scenario: Installed across 12V DC input of embedded gate drivers in motor inverters to absorb IGBT switching spikes and bus overvoltage. IC Role / Device Role / Timing Role: Fast-acting shunt device parallel to bulk input capacitor, activated before upstream fuses open. Use Value: Sustains 53A peak pulse current without degradation, preventing MOSFET gate oxide rupture during 600V/10µs transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Lower 600W rating but SMB package (smaller footprint); 7.0V VRWM, 10.5V VC @ 53.5A | Suitable for space-constrained PCBs; higher thermal resistance (RθJA = 110°C/W) limits sustained power handling | Select when board area is critical and surge duty cycle is low; verify thermal relief via 25mm² copper pour |
| 1.5KE7.5CA | Same DO-15 package but 1500W rating; 7.5V VRWM, 12.0V VC @ 125A IPP | Higher clamping voltage reduces protection margin for 5V systems; better for 12V/24V rails with larger surge budgets | Choose for enhanced energy handling in heavy-duty industrial controls where 12.0V clamping is acceptable |
Compared with SMBJ7.0CA and 1.5KE7.5CA, P6KE7V5CA-T offers optimal balance of clamping voltage (11.3V), package familiarity (DO-15), and proven automotive qualification history - making it preferred for legacy designs requiring direct replacement and AEC-Q101-aligned stress testing.

FAQ
Is P6KE7V5CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE6V8(C)A through P6KE400(C)A family, including P6KE7V5CA-T, as noted in DS21502 Rev. 20-4. Aetrix Electronics maintains limited legacy stock with full traceability and offers qualified alternatives with cross-reference support for ongoing production needs.
What is the difference between P6KE7V5A-T and P6KE7V5CA-T?
P6KE7V5A-T is unidirectional (cathode-banded), conducting only in reverse bias; P6KE7V5CA-T is bidirectional (no cathode band), providing symmetrical clamping for AC or floating circuits. Their electrical specs (VRWM, VBR, VC) are identical, but polarity handling differs fundamentally.
Can P6KE7V5CA-T be used in place of a 5.5V-rated TVS?
No - its 6.40V VRWM exceeds typical 5V rail tolerances; using it risks premature conduction during normal operation. For 5V systems, select a TVS with VRWM ≤ 5.25V (e.g., SMAJ5.0CA) to ensure sufficient margin below 5.5V absolute maximum ratings.
Does P6KE7V5CA-T meet AEC-Q101 requirements?
While not explicitly certified to AEC-Q101 in public documentation, Diodes states that automotive-grade versions of this family are manufactured in IATF 16949-certified facilities and support PPAP. Customers requiring formal qualification must request specific AEC-Q101 test reports from Diodes or authorized distributors.
