Product details
Overview
P6KE75CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of DC power rails and signal lines. It features a 64.1V reverse standoff voltage (VRWM), 71.3V minimum breakdown voltage (VBR), 103V maximum clamping voltage (VC) at 5.8A peak pulse current (IPP), and fast response time for ESD and surge suppression in industrial power supplies.
For engineers reviewing the P6KE75CA-T datasheet, P6KE75CA-T pinout, P6KE75CA-T application, or P6KE75CA-T equivalent, this part serves as a leaded, unidirectional/bidirectional TVS solution with verified clamping performance, thermal derating curves, and RoHS-compliant plating - critical for automotive-grade board-level surge immunity design and IEC 61000-4-2/4-5 compliance validation.
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 junction ensures stable VBR tolerance (±5% typical) and low leakage (<5 µA at VRWM) under steady-state conditions.
The device delivers 600W peak pulse power (10/1000 µs waveform) with clamping voltage tightly bounded at 103V, supporting robust protection of 75V-rated systems against lightning-induced surges (IEC 61000-4-5 Level 3) and contact ESD events (IEC 61000-4-2 ±8 kV air/±4 kV contact).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000 µs waveform); sustains single high-energy transients without failure |
| Reverse Standoff Voltage | 64.1V (VRWM); defines maximum continuous operating voltage before significant leakage |
| Breakdown Voltage | 71.3V min @ 1mA (VBR); onset of avalanche conduction under transient stress |
| Clamping Voltage | 103V max @ 5.8A IPP; limits voltage seen by protected circuit during surge |
| Peak Pulse Current | 5.8A (IPP); maximum surge current the device safely clamps at rated VC |
| Package | DO-15; axial-leaded, through-hole mountable with 0.4g mass and UL 94V-0 rating |
| Thermal Resistance | RθJA = 75°C/W; enables thermal management on standard FR-4 PCBs with minimal copper area |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), cathode band not marked on bidirectional version (P6KE75CA-T). Leads are solderable per MIL-STD-202, Method 208; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Reversible terminals | Bidirectional symmetry: either lead functions as anode or cathode depending on polarity of applied transient |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables single-device protection against IEC 61000-4-5 1kV/2Ω surge waveforms on 48V–75V rails |
| Glass-passivated die | Ensures long-term parameter stability and reduced parameter drift under thermal cycling |
| Bidirectional configuration | Eliminates need for polarity-aware layout; protects AC signals, differential buses, and floating sensors |

Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: 72V battery-fed DC-DC converter input stage exposed to load dump and jump-start transients. IC Role / Device Role: Primary overvoltage clamp at input filter stage, shunting surge energy to ground before regulator IC. Use Value: Clamps to ≤103V during 5.8A surge, preventing damage to downstream 80V-rated MOSFETs and controllers. |
Use Scenario: LIN bus transceiver interface subjected to ISO 7637-2 Pulse 1/2a/5a transients in vehicle cabin electronics. IC Role / Device Role: Bidirectional line protector placed between transceiver and connector, referenced to local ground. Use Value: Symmetric clamping preserves signal integrity on bidirectional LIN bus while meeting ISO 10605 ESD requirements. |
| Telecom Remote Radio Unit (RRU) | Smart Meter AC Mains Interface |
|
Use Scenario: +48V DC power feed to outdoor RRU unit vulnerable to induced lightning surges on long cable runs. IC Role / Device Role: First-stage TVS on DC input, coordinated with upstream MOV and downstream π-filter. Use Value: Fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 1.45) minimize let-through energy to sensitive RF front-end. |
Use Scenario: Microcontroller-based meter with isolated RS-485 interface connected to mains-powered concentrator via long twisted pair. IC Role / Device Role: Secondary protection on isolated data lines, placed after isolation barrier but before transceiver. Use Value: Bidirectional operation safeguards against common-mode surges crossing isolation boundary without polarity biasing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Surface-mount SMB package; same 64.1V VRWM, 103V VC, but lower 600W rating derated at higher ambient temperatures | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs or high-vibration environments | Select when board space is constrained and automated SMT placement is available. |
| P6KE75A-T | Unidirectional version; identical VRWM, VBR, VC, and IPP, but asymmetric conduction (cathode-marked) | Requires correct polarity orientation; cannot protect AC or floating nodes without external biasing | Choose only for DC rails with fixed polarity and where cost-per-unit favors unidirectional variants. |
Compared with SMBJ75CA and P6KE75A-T, P6KE75CA-T provides mechanical robustness via axial leads, eliminates polarity dependency, and maintains full 600W rating in through-hole mounting - making it optimal for field-replaceable modules, industrial controls, and legacy designs requiring leaded reliability.

FAQ
Is P6KE75CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE75CA-T (and entire P6KE series), marking it as obsolete per DS21502 Rev. 20-4. Aetrix Electronics holds remaining authorized inventory with full traceability, but no new production is scheduled. Customers should plan for last-time-buy or migration to SMBJ or SMF series alternatives.
What is the meaning of the "C" suffix in P6KE75CA-T?
The "C" suffix explicitly denotes bidirectional construction: the device exhibits symmetrical avalanche characteristics in both forward and reverse bias, enabling protection of AC-coupled circuits, differential buses, or floating nodes without polarity constraints - unlike unidirectional P6KE75A-T which conducts only in reverse bias.
Can P6KE75CA-T be used in automotive applications?
While P6KE75CA-T is not AEC-Q200 qualified, Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - all of which apply to this part's production history. It has been widely deployed in non-safety-critical BCM and infotainment subsystems, but formal qualification requires direct engagement with Diodes' automotive team.
How does the DO-15 package affect thermal performance compared to SMD equivalents?
The DO-15 package offers higher thermal mass and superior heat dissipation via axial leads soldered to large copper pours, delivering RθJA = 75°C/W - significantly better than SMB/SMA packages under natural convection. This allows sustained operation near 75°C ambient without forced cooling, whereas SMD variants typically require thermal vias and extensive copper to match steady-state power handling.
