Product details
Overview
P4KE75A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 103 V clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines of automotive sensor modules and industrial PLC inputs.
For engineers reviewing the P4KE75A-E3/54 datasheet, P4KE75A-E3/54 pinout, P4KE75A-E3/54 application, or P4KE75A-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 μs transients, DO-41 lead-form compatibility with through-hole PCB layouts, unidirectional polarity marking (cathode band), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 64.1 V, it avalanches at VBR = 71.3–78.8 V (tested at 1.0 mA), limiting transient energy by diverting up to 3.9 A to ground while clamping to ≤103 V. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance for repeatable clamping.
Thermal design relies on RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm); maximum junction temperature is 175 °C, enabling operation in under-hood automotive environments. The device supports soldering per JESD 22-B106 (275 °C, 10 s) and meets UL 94 V-0 flammability requirements.

Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor outputs (e.g., oxygen sensors, throttle position) from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt clamp on 12 V supply rail and signal lines; responds within <1 ns to suppress >100 V transients. Use Value: Prevents latch-up or gate oxide damage in automotive-grade MCUs by limiting VC to 103 V during ISO 7637-2 Pulse 5a (load dump). |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Standoff-mode protector on 24 V DC inputs; conducts only during >64.1 V surges, maintaining normal logic levels otherwise. Use Value: Eliminates need for external series impedance or RC snubbers by absorbing 400 W pulses without degradation over 100,000 cycles. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for USB-C PD and laptop chargers. IC Role / Device Role / Timing Role: Clamp on +5 V/+20 V output rails; activated only during fault conditions (e.g., feedback loop failure). Use Value: Maintains tight output regulation during normal operation (leakage <1.0 μA), then clamps to 103 V to protect downstream USB-PD controllers. |
Use Scenario: Surge protection on Ethernet PHY interface power pins (e.g., 3.3 V bias rails) in PoE-powered switches and base stations. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF) unidirectional clamp; placed adjacent to RJ45 connector to minimize trace inductance. Use Value: Limits transient overshoot to <103 V during IEC 61000-4-5 4 kV tests while adding negligible signal distortion to 100BASE-TX data paths. |
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 VWM, 103 V VC @ 3.9 A, same PPPM = 400 W but surface-mount format. | Requires SMT reflow process and PCB redesign; unsuitable for legacy through-hole assemblies. | Select SMBJ75A only when board space constraints mandate SMT or thermal management requires lower RθJA (50 °C/W typical). |
| 1.5KE75A | Same DO-41 package, 75 V VWM, but higher PPPM = 1500 W and VC = 121 V @ 12.3 A; larger junction area. | Over-spec'd for 400 W use cases; higher clamping voltage increases risk to sensitive 3.3 V logic. | Choose 1.5KE75A only when protecting high-energy circuits (e.g., motor drives) where 121 V clamping is acceptable and 1500 W rating is mandatory. |
Compared with SMBJ75A and 1.5KE75A, P4KE75A-E3/54 delivers optimal balance of through-hole manufacturability, 103 V clamping headroom for 3.3 V/5 V systems, and AEC-Q101 qualification - making it the preferred choice for cost-sensitive, high-reliability automotive and industrial designs requiring DO-41 compatibility.

FAQ
What is the clamping voltage of the P4KE75A-E3/54 under a 10/1000 μs surge?
The P4KE75A-E3/54 clamps to a maximum of 103 V when subjected to its rated peak pulse current of 3.9 A with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 12 V or 24 V system ICs.
Is the P4KE75A-E3/54 suitable for automotive applications?
Yes, the P4KE75A-E3/54 is AEC-Q101 qualified (as confirmed in the "Notes" section of Vishay document 88365), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its 175 °C maximum junction temperature and robust surge handling align with ISO 7637-2 and ISO 16750-2 environmental stress requirements.
How does the P4KE75A-E3/54 differ from bidirectional variants like P4KE75CA?
The P4KE75A-E3/54 is unidirectional, featuring a cathode band for polarity identification and conducting only in reverse breakdown; P4KE75CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The P4KE75A-E3/54 offers lower leakage (<1.0 μA at VWM) and is used where DC bias exists, whereas P4KE75CA suits AC-coupled or floating signal lines.
What is the thermal resistance of the P4KE75A-E3/54, and how does it affect layout?
The P4KE75A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient (RθJA) of 100 °C/W with 10 mm lead length. To maintain TJ ≤ 175 °C, PCB layout must provide adequate copper pour on both leads and avoid excessive trace length - especially critical in high-duty-cycle surge environments like industrial motor controls.
Does the P4KE75A-E3/54 meet RoHS and REACH compliance?
Yes, the "E3" suffix in P4KE75A-E3/54 indicates RoHS-compliant construction per EU Directive 2011/65/EU, with lead-free matte tin plating and halogen-free molding compound meeting Vishay's material categorization standard (document 99912).
