Product details
Overview
P6KE75A-T from Diodes Incorporated 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 64.1V reverse standoff voltage (VRWM), 71.3V minimum breakdown voltage (VBR), 103V maximum clamping voltage (VC) at 5.8A peak pulse current, and DO-15 glass-passivated package - used in industrial power supplies, automotive body control modules, and telecom interface protection.
For engineers reviewing the P6KE75A-T datasheet, P6KE75A-T pinout, P6KE75A-T application, or P6KE75A-T equivalent, key selection criteria include clamping performance under 10/1000μs surge, thermal derating above +25°C ambient, unidirectional polarity marking (cathode band), and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
This TVS diode operates as a fast-acting shunt protector triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5μA @ VRWM), while the DO-15 package provides 20°C/W junction-to-case thermal resistance for reliable power dissipation during transient events.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity requirements when applied with appropriate series impedance. It is not rated to AEC-Q101 but supports automotive-adjacent applications where PPAP or IATF 16949 traceability is not mandated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000μs waveform; defines maximum single-event surge energy handling) |
| Reverse Standoff Voltage | 64.1V (maximum continuous DC or RMS voltage before significant leakage) |
| Breakdown Voltage | 71.3V min @ 1mA (avalanche onset threshold; tight ±5% tolerance ensures predictable triggering) |
| Clamping Voltage | 103V max @ 5.8A IPP (voltage seen by protected circuit during worst-case surge) |
| Package | DO-15 (axial-leaded, 0.4g weight, UL 94V-0 molded plastic housing) |
| Thermal Resistance | RθJA = 75°C/W (limits steady-state power to 5.0W at TL = +75°C on 40mm² copper) |
| Leakage Current | <5μA @ 64.1V (minimizes standby power loss in high-impedance bias networks) |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode indicated by painted band on body. Leads are tin-plated, 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; carries full surge current during clamping |
| Cathode | Protected line terminal | Connected to line under protection (e.g., +12V rail); marked with band; reverse-biased during surge |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV line-earth) without cascading failure |
| Glass-passivated die construction | Ensures long-term parameter stability and reduced parameter drift over temperature and life cycles |
| Fast response time (<1ps) | Clamps transients before downstream ICs experience overstress - critical for protecting 3.3V/5V logic interfaces |
| RoHS-compliant lead finish | Supports lead-free reflow assembly (J-STD-020 Level 1) without solder joint reliability concerns |
| Unidirectional polarity | Prevents unwanted conduction during normal forward-biased operation in DC supply rails |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|

Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary shunt clamp limiting transient voltage to ≤103V during 10/1000μs surges. Use Value: Prevents damage to upstream rectifier diodes and downstream DC-DC controllers by clamping within safe SOA limits. |
Use Scenario: CAN bus power line (VBAT) in non-safety-critical BCM subsystems subject to ISO 7637-2 Pulse 1/2a/5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fused B+ and ground to suppress negative-going transients. Use Value: Maintains <5μA leakage at 24V nominal, avoiding battery drain while clamping to 103V during 100V/50ms load dump events. |
| Telecom Interface Surge Protection | Consumer Appliance Motor Drive Supply |
|
Use Scenario: RS-485 transceiver power rail (VCC) in outdoor security camera node subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level TVS after common-mode choke, clamping differential-mode overvoltage. Use Value: Limits VCC excursion to 103V during 1kV/0.5Ω IEC 61000-4-5 surge, preserving transceiver latch-up immunity. |
Use Scenario: 12V logic supply feeding H-bridge gate drivers in smart washing machine motor control board. IC Role / Device Role / Timing Role: Unidirectional suppressor on driver IC VDD rail to absorb back-EMF spikes from brushed DC motor commutation. Use Value: Withstands repetitive 5.8A pulses at 4-pulse/minute duty cycle without thermal runaway (RθJA = 75°C/W). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A (Diodes Inc.) | Same VRWM (64.1V) and VC (103V), but SMC package (higher PPK = 600W, lower RθJA = 50°C/W) | Surface-mount layout; better thermal performance in dense PCBs; requires reflow-compatible footprint | Select SMBJ75A for space-constrained designs needing improved thermal management and automated assembly. |
| P6KE75CA (Diodes Inc.) | Bidirectional version; identical VRWM/VBR/VC specs but symmetric clamping for AC or floating lines | Used where line polarity is undefined (e.g., Ethernet transformer center taps, AC sensor inputs) | Choose P6KE75CA only when bidirectional protection is required; unidirectional P6KE75A-T avoids unnecessary leakage in DC rails. |
Compared with SMBJ75A, P6KE75A-T offers lower assembly cost and legacy through-hole compatibility but higher thermal resistance; versus P6KE75CA, it delivers lower leakage and simpler polarity routing in fixed-polarity DC systems.

FAQ
Is P6KE75A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE75A-T (document DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for last-time buy and obsolescence mitigation planning.
What is the meaning of the "-T" suffix in P6KE75A-T?
The "-T" suffix denotes tape-and-reel packaging: 4,000 units per 13-inch reel, compatible with automated pick-and-place equipment. The base part number P6KE75A refers to the same electrical and mechanical specifications in bulk or ammo-pack formats.
Can P6KE75A-T be used in AEC-Q101 qualified automotive designs?
No - this device is not AEC-Q101 qualified. Diodes' datasheet explicitly states that automotive-qualified parts require separate change control, PPAP capability, and IATF 16949 manufacturing; P6KE75A-T lacks those certifications and is intended for industrial/commercial use only.
How does P6KE75A-T differ from P6KE75CA?
P6KE75A-T is unidirectional (cathode-banded), with leakage specified only under reverse bias; P6KE75CA is bidirectional (no band), offering symmetrical clamping for AC or floating nodes. Both share identical VRWM (64.1V), VBR (71.3V min), and VC (103V), but P6KE75CA exhibits double the IR limit for VR ≤10V - irrelevant here since VRWM is 64.1V.
