Product details
Overview
P4KE75AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. 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 signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE75AHE3/54 datasheet, P4KE75AHE3/54 pinout, P4KE75AHE3/54 application, or P4KE75AHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, DO-41 mechanical dimensions, and real-world clamping behavior under transient surge conditions - critical for ESD and load-dump immunity validation.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation with ≤1.0 μA leakage at 64.1 V, then rapidly avalanches to limit transients above 71.3 V. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance - key for consistent clamping across repetitive surges.
Thermal design is constrained by RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). The device is rated for TJ up to +175 °C and qualified to AEC-Q101, confirming suitability for under-hood automotive environments where thermal cycling and vibration resilience are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (min/max) | 71.3 V / 78.8 V at 1.0 mA - precise avalanche initiation range; enables predictable turn-on during transients. |
| VC @ IPPM | 103 V at 3.9 A - clamped voltage during 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 400 W - peak pulse power handling capability; supports automotive load-dump (ISO 7637-2 Pulse 5a) compliance. |
| IFSM | 40 A - 8.3 ms half-sine surge current rating; validates robustness against inductive switching events. |
| TJ max | +175 °C - maximum junction temperature; allows operation in high-ambient under-hood locations. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock. |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Cathode indicated by color band on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanches when voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over time and temperature; eliminates surface degradation risks in humid or contaminated environments. |
| 400 W peak pulse power (10/1000 μs) | Validates protection against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) without derating. |
| AEC-Q101 qualification | Confirms reliability for automotive applications including engine control modules, body controllers, and ADAS sensor interfaces. |
| RθJL = 66 °C/W | Enables direct PCB trace heat sinking; supports >1.5 W continuous dissipation with minimal lead length (<10 mm). |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage exposure to downstream ICs - critical for 5 V or 3.3 V logic-level interface protection. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|

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; 75 V VWM, 83.3 V VBR min, 121 V VC @ 3.3 A; 600 W PPPM. | Higher clamping voltage (+18 V) but greater surge capacity; better suited for higher-energy transients where board space allows SMC footprint. | Select SMBJ75A when surge energy exceeds 400 W and PCB layout accommodates larger SMC package. |
| 1.5KE75A | DO-201AD package; identical VWM/VBR/VC specs; same 400 W rating but higher RθJA (75 °C/W vs. 100 °C/W). | Lower thermal resistance improves power handling in confined spaces; preferred for high-density industrial PCBs with limited copper area. | Choose 1.5KE75A when thermal management is constrained and lead-length-dependent cooling is impractical. |
Compared with SMBJ75A and 1.5KE75A, P4KE75AHE3/54 offers AEC-Q101 qualification and DO-41 compatibility with legacy through-hole designs - making it optimal for cost-sensitive automotive replacements and retrofits requiring proven reliability and drop-in mechanical fit.

FAQ
What is the clamping voltage of P4KE75AHE3/54 and how does it protect downstream components?
The P4KE75AHE3/54 has a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current (10/1000 μs waveform). This value defines the highest voltage imposed on the protected circuit during a transient event. By limiting overvoltage to this level, the P4KE75AHE3/54 prevents insulation breakdown, gate oxide rupture in MOSFETs, and latch-up in microcontrollers - ensuring system-level robustness against ISO 7637-2 load-dump and ESD events.
Is P4KE75AHE3/54 suitable for automotive applications?
Yes, P4KE75AHE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing. Its 175 °C maximum junction temperature, glass-passivated junction, and validated performance under thermal cycling and humidity testing make it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS sensor interfaces.
How does the DO-41 package of P4KE75AHE3/54 affect thermal performance?
The DO-41 package of P4KE75AHE3/54 provides RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, 10 mm lead length). This means effective thermal management requires short, wide PCB traces to the ground plane or direct lead soldering to copper pours. For continuous 1.5 W dissipation, ambient temperature must remain below 75 °C - confirmed via the power derating curve in Figure 5 of the Vishay datasheet 88365.
What is the difference between P4KE75AHE3/54 and P4KE75A-E3/54?
P4KE75AHE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, while P4KE75A-E3/54 is commercial grade with JESD 201 Class 1A whisker testing. Both share identical electrical specifications (VWM, VBR, VC, PPPM), DO-41 packaging, and RoHS compliance. The HE3 suffix denotes enhanced reliability for automotive use, whereas E3 is intended for consumer and industrial applications with less stringent qualification requirements.
Can P4KE75AHE3/54 be used in bidirectional configurations?
No, P4KE75AHE3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., P4KE75CA). Using P4KE75AHE3/54 in reverse-biased AC signal paths would result in forward conduction during negative half-cycles - causing excessive leakage, overheating, and potential failure. Always match device polarity to circuit topology.
