Product details
Overview
P6KE7V5A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary 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 53.0A peak pulse current, and DO-15 axial package-used in automotive body control modules to clamp load-dump transients.
For engineers reviewing the P6KE7V5A-T datasheet, P6KE7V5A-T pinout, P6KE7V5A-T application, or P6KE7V5A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, 8.3ms surge current handling capability, unidirectional polarity alignment with DC rail topology, and DO-15 thermal derating above +25°C ambient.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <500µA leakage at VRWM; during transients exceeding VBR, it avalanches into low-impedance conduction to limit VC to ≤11.3V. Its glass-passivated junction ensures stable breakdown and fast response (<1.0ns).
The device is rated for 600W non-repetitive peak pulse power (tP = 1.0ms), 100A 8.3ms half-sine forward surge current, and steady-state dissipation of 5.0W at TL = +75°C on 40mm² copper land-enabling robust protection without active thermal management in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000µs waveform; defines maximum transient energy absorption before failure) |
| Reverse Standoff Voltage | 6.40V (maximum continuous DC voltage before significant leakage; sets minimum operating rail margin) |
| Breakdown Voltage | 7.13V min @ 10mA (avalanche initiation threshold; ensures reliable turn-on before downstream IC damage) |
| Clamping Voltage | 11.3V max @ 53.0A (voltage seen by protected circuit during worst-case surge; must be below IC absolute max rating) |
| Package | DO-15 (axial leaded plastic; UL 94V-0 rated; enables manual soldering and through-hole mounting in high-vibration environments) |
| Operating Temp Range | −55°C to +175°C (supports under-hood automotive placement without derating loss) |
Pinout & Package
DO-15 package: axial leads, molded plastic body, cathode indicated by band. Total weight ≈0.4g. Moisture sensitivity level 1 (J-STD-020). Lead finish: matte tin, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; completes clamping loop during positive transients |
| Cathode | Protected line terminal | Connected to rail being protected (e.g., 5V supply); avalanche conduction occurs from cathode to anode when VRWM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) up to 120V/100ms without degradation |
| Glass passivated die | Ensures stable VBR over temperature and lifetime; eliminates parameter drift in automotive thermal cycling |
| Fast response time | Sub-nanosecond turn-on limits voltage overshoot during ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) |
| RoHS-compliant lead finish | Matte tin plating enables lead-free reflow compatibility while maintaining solder joint reliability |
Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |
|---|---|
Use Scenario: 12V battery rail in BCM exposed to load-dump transients up to 120V/100ms during alternator disconnection. IC Role / Device Role / Timing Role: Primary shunt clamping element placed between VBAT and GND, upstream of LDOs and microcontrollers. Use Value: Limits rail voltage to ≤11.3V during surge, preventing latch-up or oxide breakdown in 5V/3.3V logic ICs. |
Use Scenario: 24V digital input channel in industrial PLC subjected to inductive kickback from solenoid switching. IC Role / Device Role / Timing Role: Front-end transient suppressor on field-side input, paired with series resistor and optocoupler. Use Value: Absorbs >95% of 600W surge energy within 1ms, preserving signal integrity and enabling <1µs response to valid input edges. |
| DC Power Supply Input Stage | Telecom Line Interface |
Use Scenario: Secondary-side 5V output of AC/DC adapter exposed to conducted noise from EMI filters and rectifier ringing. IC Role / Device Role / Timing Role: Final-stage rail clamp adjacent to point-of-load converters and USB ports. Use Value: Clamps 100V/1ms surges to 11.3V, protecting USB PHYs and Type-C CC logic from overvoltage damage. |
Use Scenario: -48V telecom power feed line subject to lightning-induced surges per ITU-T K.20/21. IC Role / Device Role / Timing Role: First-line protector on -48V bus, mounted before DC-DC isolation stage. Use Value: Withstands 10kA 8/20µs surges via parallel staging; single-device VC of 11.3V ensures safe interface to -48V tolerant transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0V VRWM; 100W peak power; lower clamping (11.2V @ 32.1A) | Lower surge capacity suits consumer-grade 5V rails; unsuitable for automotive load-dump | Select when board space is constrained and surge energy ≤100W; verify thermal pad layout for SMB footprint |
| 1.5KE7.5A | DO-201AD package; 7.5V VRWM; 1500W peak power; higher clamping (12.9V @ 116A) | Higher power rating supports heavy-duty industrial motor drives; larger footprint requires more PCB area | Choose for 24V/48V systems needing >600W margin; confirm lead length and mounting clearance for DO-201AD |
Compared with P6KE7V5A-T, SMBJ7.0A offers smaller size but insufficient energy handling for automotive use, while 1.5KE7.5A delivers higher surge capacity at the cost of larger DO-201AD packaging and elevated clamping-making P6KE7V5A-T the optimal balance of DO-15 fit, 600W rating, and 11.3V VC for cost-sensitive 12V embedded systems.

FAQ
Is P6KE7V5A-T still in active production?
No-P6KE7V5A-T is officially obsolete per Diodes' DS21502 Rev. 20-4 (August 2024). It remains available through Aetrix Electronics' legacy inventory and authorized distributor channels, with full traceability and documentation. Engineering support for replacement selection is provided for ongoing designs.
What is the maximum allowable junction temperature during surge events?
The P6KE7V5A-T has a maximum junction temperature of +175°C. During a 1.0ms 600W pulse, junction temperature rise is limited by RθJC = 20°C/W and thermal mass; peak Tj remains below 150°C under typical PCB mounting conditions, ensuring no permanent parametric shift.
Can P6KE7V5A-T be used in bidirectional configurations?
No-P6KE7V5A-T is unidirectional only (denoted by "A" suffix). Bidirectional variants carry "CA" suffix (e.g., P6KE7V5CA). Using the unidirectional part in AC or floating-bus applications risks reverse breakdown and failure; always match polarity to system grounding architecture.
How does its clamping performance compare to polymer-based TVS devices?
P6KE7V5A-T provides deterministic, low-impedance clamping (11.3V @ 53A) with sub-ns response, unlike polymer TVS which exhibit voltage-dependent resistance and slower turn-on. It is preferred where precise voltage limiting and minimal overshoot are required-especially in logic-rail protection where polymer devices may allow damaging excursions.
