Product details
Overview
P6KE75AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum stand-off voltage (VWM), 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE75AHE3/54 datasheet, P6KE75AHE3/54 pinout, P6KE75AHE3/54 application, or P6KE75AHE3/54 equivalent, this device is evaluated for robust ESD and surge immunity in 12 V–24 V systems where fast response (<1 ns), low leakage (<1 μA at VWM), and AEC-Q101 qualification are required.
Technical Context
The P6KE75AHE3/54 uses a glass-passivated silicon junction to achieve sub-nanosecond response to transients while maintaining stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle. Its unidirectional polarity enables cathode-referenced protection on positive-rail circuits without reverse conduction path concerns.
Thermal design is supported by a 20 °C/W junction-to-lead thermal resistance and 175 °C maximum junction temperature, enabling reliable operation in high-ambient environments when mounted on PCB copper pours or short leads. The DO-15 package provides mechanical robustness and UL 94 V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1.0 mA test current - defines precise turn-on threshold for overvoltage triggering |
| VWM | 64.1 V - maximum continuous working voltage before leakage exceeds 1 μA, ensuring no false triggering in 60 V nominal systems |
| VC @ IPPM | 103 V at 5.8 A - limits downstream IC stress during 600 W transient events |
| PPPM | 600 W - handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation |
| IFSM | 100 A - withstands 8.3 ms half-sine surge per JESD 22-B102, supporting fuse coordination |
| TJ max. | 175 °C - enables operation in under-hood automotive and industrial control cabinet environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD HBM ≥ 8 kV |

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN transceivers and Hall-effect sensor outputs from load dump and inductive switching spikes in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Primary clamping element placed between sensor VCC pin and chassis ground, activated within <1 ns of overvoltage event. Use Value: Limits voltage seen by 3.3 V or 5 V sensor ASICs to ≤103 V, preventing latch-up or gate oxide damage during 100 V/100 ms load dump events. |
Use Scenario: Safeguarding 4–20 mA current loop receivers and ADC front-ends against field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS installed across input terminals (signal-to-ground), coordinated with series current-limiting resistor. Use Value: Clamps 1 kV/0.5 J transients to <103 V within 1 ns, preserving ±16 V common-mode input range of precision instrumentation amplifiers. |
| DC Power Rail Protection | Telecom Line Card Surge Guard |
Use Scenario: Secondary overvoltage suppression on 24 V DC distribution rails feeding motor drivers and solenoid controllers in material handling equipment. IC Role / Device Role / Timing Role: Standoff-rated protector placed upstream of DC-DC converters, sized to coordinate with upstream fuses. Use Value: Withstands 100 A surge for 8.3 ms (IFSM) and clamps 600 W pulses to 103 V, preventing converter shutdown or MOSFET avalanche failure. |
Use Scenario: Front-end transient suppression on -48 V telecom power feeds and RS-485 data lines exposed to lightning-induced surges in outdoor base stations. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to -48 V rail, absorbing positive-going surges toward ground while blocking reverse conduction. Use Value: Maintains 64.1 V standoff to avoid interference with -48 V bias, yet clamps 103 V during 600 W transients - compatible with TI TPS23753 or MAX13487 interface ICs. |
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 | DO-214AA package (SMB), 75 V VBR, same 600 W rating but lower IPPM (5.3 A) and higher VC (121 V) | Surface-mount layout; less suitable for through-hole legacy designs or high-vibration environments requiring axial lead retention | Select SMBJ75A only when board space constraints mandate SMD packaging and higher VC margin is acceptable |
| 1.5KE75A | Same DO-15 package, 75 V VBR, but 1500 W rating (IPPM = 12.3 A), higher VC (129 V), and no AEC-Q101 qualification | Higher-energy surge handling for AC mains-derived DC supplies; lacks automotive reliability validation | Choose 1.5KE75A for non-automotive industrial power supplies needing >600 W headroom, but not for AEC-Q101–mandated designs |
Compared with SMBJ75A and 1.5KE75A, P6KE75AHE3/54 delivers optimal balance of AEC-Q101 qualification, 103 V clamping performance, and DO-15 mechanical robustness - making it the preferred choice for automotive and harsh-environment industrial deployments where reliability and precise voltage limiting are critical.

FAQ
What is the clamping voltage of P6KE75AHE3/54 and how is it measured?
The P6KE75AHE3/54 has a maximum clamping voltage (VC) of 103 V, measured at 5.8 A peak pulse current using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during a standardized surge event and is guaranteed across the full operating temperature range of -55 °C to +175 °C. The P6KE75AHE3/54 achieves this clamping performance via its glass-passivated junction and optimized doping profile.
Is P6KE75AHE3/54 suitable for automotive applications?
Yes, P6KE75AHE3/54 is AEC-Q101 qualified and specifically rated for automotive use - including engine control units, body electronics, and ADAS sensor modules. Its 175 °C maximum junction temperature, robust DO-15 mechanical construction, and validated performance under temperature cycling, HTRB, and ESD testing confirm suitability for under-hood and cabin-mounted systems. The HE3 suffix explicitly denotes AEC-Q101 qualification for the P6KE75AHE3/54.
What does the "HE3/54" suffix mean in P6KE75AHE3/54?
The "HE3" suffix in P6KE75AHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "/54" denotes the preferred package code for 13-inch paper tape and reel delivery, with a base quantity of 4000 units per reel. This ordering format ensures traceability, consistent lead finish (matte tin), and compliance with automotive supply chain requirements for the P6KE75AHE3/54.
How does P6KE75AHE3/54 differ from bidirectional variants like P6KE75CA?
P6KE75AHE3/54 is unidirectional, with a cathode band marking and designed to clamp only positive transients relative to ground - ideal for protecting positive DC rails. In contrast, P6KE75CA is bidirectional, symmetric in both directions, and used in AC-coupled or differential signal paths. The P6KE75AHE3/54 offers tighter VBR tolerance (71.3–78.8 V) and lower VC (103 V) than P6KE75CA (VC = 121 V), making it more effective for single-polarity DC protection where reverse conduction must be avoided.
What is the maximum leakage current of P6KE75AHE3/54 at its stand-off voltage?
The P6KE75AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 64.1 V, measured at 25 °C. This ultra-low leakage ensures minimal power loss and no interference with sensitive analog or low-power digital circuits during normal operation. Leakage remains below 5 μA up to 85 °C, supporting reliable performance in industrial and automotive ambient conditions for the P6KE75AHE3/54.
