Product details
Overview
P6KE75A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum standoff voltage (VWM), 103 V clamping voltage at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE75A-E3/54 datasheet, P6KE75A-E3/54 pinout, P6KE75A-E3/54 application, or P6KE75A-E3/54 equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, real-world clamping behavior, thermal derating guidance, and qualified AEC-Q101 alternatives for robust ESD/surge design validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients while maintaining low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, consistent with P6KE220A and lower-voltage variants.
The P6KE75A-E3/54 is rated for -55 °C to +175 °C operating junction temperature, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting reliable operation under pulsed surge conditions up to 100 A IFSM (8.3 ms half-sine) and 5.0 W steady-state dissipation on infinite heatsink at TL = 75 °C.
Key Specifications

| PPPM | 600 W peak pulse power - sustains transient energy absorption without failure under standardized lightning/surge waveforms |
| TJ max. | +175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | DO-214AA package; 75 V VWM, 103 V VC @ 5.8 A; same PPPM but lower IFSM (100 A vs. SMBJ's 70 A) | Surface-mount layout; requires PCB rework; better high-frequency impedance due to lower parasitic inductance | Select when space-constrained SMT assembly is required and thermal path supports RθJA = 50 °C/W |
| 1.5KE75A | Same DO-15 package; 75 V VWM, 108 V VC @ 5.5 A; higher VC (+5 V), lower PPPM (1500 W but derated to 600 W at TA > 25 °C) | Legacy through-hole alternative; identical mounting but less precise clamping and no AEC-Q101 qualification | Select only for cost-sensitive commercial designs where AEC-Q101 is not mandated and 5 V higher clamping is acceptable |
Compared with SMBJ75A and 1.5KE75A, P6KE75A-E3/54 offers AEC-Q101 qualification in DO-15, tighter VC tolerance, and optimized thermal resistance for lead-based conduction - making it preferred for automotive and industrial through-hole deployments requiring long-term reliability.

FAQ
What is the maximum clamping voltage of the P6KE75A-E3/54 under standard surge conditions?
The P6KE75A-E3/54 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream components during surge events. The P6KE75A-E3/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C), with minimal drift due to its glass-passivated junction structure.
Is the P6KE75A-E3/54 suitable for automotive applications?
Yes, the P6KE75A-E3/54 is AEC-Q101 qualified, confirming its reliability for automotive use in powertrain, body electronics, and ADAS subsystems. It meets requirements for temperature cycling, high-temperature reverse bias, and ESD immunity. The P6KE75A-E3/54 is commonly deployed in 12 V/24 V battery line protection and sensor power conditioning where ISO 7637-2 Pulse 5a compliance is required.
How does the P6KE75A-E3/54 differ from bidirectional TVS diodes like P6KE75CA?
The P6KE75A-E3/54 is unidirectional and features a cathode band for polarity identification, whereas P6KE75CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The P6KE75A-E3/54 has a forward voltage drop (~3.5 V at 50 A), making it unsuitable for AC signal lines but ideal for DC rail protection. Its VWM (64.1 V) and VBR (71.3–78.8 V) apply only in reverse bias, unlike the CA variant's dual-direction specs.
What is the thermal resistance and how does it affect PCB layout for the P6KE75A-E3/54?
The P6KE75A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To maintain reliability under repeated surges, PCB layout must maximize copper area connected to both leads - especially the cathode - to emulate an infinite heatsink condition. The P6KE75A-E3/54 achieves its rated 5.0 W power dissipation only when lead temperature (TL) is held at 75 °C, per Figure 5 in the datasheet.
Can the P6KE75A-E3/54 be used in parallel for higher surge current handling?
No - the P6KE75A-E3/54 is not recommended for parallel operation due to VBR mismatch (±5 % tolerance), which causes current imbalance and premature failure of the lower-VBR unit. For higher IPPM, select a single higher-power device such as 1.5KE75A (1500 W) or switch to surface-mount SMBJ75A with matched binning. The P6KE75A-E3/54 is characterized and tested as a standalone device; parallel use voids AEC-Q101 qualification and violates Vishay's application guidance.
