Product details
Overview
P4KE75CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 71.3 V minimum and 78.8 V maximum breakdown voltage at 1 mA test current, 64.1 V standoff voltage, 1.0 μA max reverse leakage at VWM, and clamps to ≤103 V at 3.9 A peak pulse current under 10/1000 μs waveform.
For engineers reviewing the P4KE75CAHE3/54 datasheet, P4KE75CAHE3/54 pinout, P4KE75CAHE3/54 application, or P4KE75CAHE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional surge protection for automotive sensor interfaces, industrial I/O lines, telecom line cards, and DC power rail transient suppression where 400 W peak pulse power and fast response are required.
Technical Context
This device operates as a voltage-clamping component in bidirectional configurations, with symmetrical avalanche breakdown behavior in both polarities. Its glass-passivated junction enables stable clamping performance and low incremental surge resistance across repetitive 10/1000 μs transients at 0.01% duty cycle.
The P4KE75CAHE3/54 is rated for 400 W peak pulse power, 1.5 W steady-state power dissipation, and operates over -55 °C to +175 °C junction temperature range. It meets JESD 201 Class 2 whisker testing and UL 94 V-0 flammability requirements via its molded epoxy DO-41 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 71.3 V min / 78.8 V max at 1 mA - defines precise clamping onset threshold for bidirectional surge events |
| Standoff Voltage (VWM) | 64.1 V - maximum continuous working voltage before significant leakage begins |
| Clamping Voltage (VC) | ≤103 V at 3.9 A IPPM - actual voltage seen by protected circuit during worst-case 10/1000 μs surge |
| Peak Pulse Power (PPPM) | 400 W - energy-handling capability for standardized lightning/surge immunity per IEC 61000-4-5 |
| Reverse Leakage (ID) | ≤1.0 μA at VWM - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | DO-214AA package, 75 V nominal VBR, same 400 W PPPM but lower RθJA (60 °C/W vs. 100 °C/W) | Better thermal performance in surface-mount layouts; requires PCB rework for through-hole replacement | Select when board space is constrained and SMT assembly is available; not drop-in compatible with P4KE75CAHE3/54 |
| 1.5KE75CA | Same DO-41 package, higher 1500 W PPPM rating, 75 V nominal VBR, but larger physical size and higher clamping voltage (121 V) | Higher energy handling for severe surge environments (e.g., outdoor telecom cabinets), but less precise clamping | Choose when legacy DO-41 footprint must be retained and surge threat level exceeds 400 W; verify system-level clamping margin |
Compared with SMBJ75CA and 1.5KE75CA, the P4KE75CAHE3/54 delivers optimal balance of AEC-Q101 qualification, compact DO-41 form factor, and tight 103 V clamping-making it preferred for cost-sensitive automotive and industrial designs where thermal derating is manageable and precise voltage limiting is critical.

FAQ
What is the breakdown voltage tolerance for P4KE75CAHE3/54?
The P4KE75CAHE3/54 has a specified breakdown voltage range of 71.3 V minimum to 78.8 V maximum at 1 mA test current, representing ±5% tolerance around the nominal 75 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge design margins.
Is P4KE75CAHE3/54 suitable for automotive applications?
Yes, the P4KE75CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its -55 °C to +175 °C operating junction temperature range, JESD 201 Class 2 whisker resistance, and validation across temperature cycling and high-acceleration stress make it appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the clamping voltage of P4KE75CAHE3/54 compare to its standoff voltage?
The P4KE75CAHE3/54 has a 64.1 V standoff voltage (VWM) and clamps to ≤103 V at its rated 3.9 A peak pulse current. This 38.9 V differential provides sufficient margin above normal operating voltage while limiting transient overvoltage to a level safe for common 75 V-rated interface ICs and microcontroller I/O structures.
Does P4KE75CAHE3/54 require polarity-aware PCB layout?
No - the P4KE75CAHE3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics; neither lead is marked, and either terminal may connect to line or reference. PCB layout can treat both leads identically, simplifying routing and eliminating orientation-dependent assembly errors.
What is the thermal resistance of P4KE75CAHE3/54, and how does it affect power handling?
The P4KE75CAHE3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W with 10 mm lead length. At 25 °C ambient, this limits continuous power dissipation to 1.5 W, but its 400 W peak pulse rating applies only for short-duration transients (≤50 ms), making thermal mass and PCB copper area more critical than steady-state RθJA for surge survival.
