Product details
Overview
P4KE75CHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and inductive switching transients. It features 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum 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.
For engineers reviewing the P4KE75CHE3/73 datasheet, P4KE75CHE3/73 pinout, P4KE75CHE3/73 application, or P4KE75CHE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), DO-41 mechanical dimensions, and real-world clamping behavior under transient stress.
Technical Context
The P4KE75CHE3/73 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 71.3–78.8 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at 64.1 V).
It delivers 103 V clamping at 3.9 A IPPM under 10/1000 μs surge, with 0.105 %/°C temperature coefficient of VBR, enabling predictable overvoltage response across –55 °C to +175 °C operating junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines reliable turn-on threshold before clamping begins |
| VWM | 64.1 V - maximum continuous reverse working voltage without significant leakage |
| VC @ IPPM | 103 V at 3.9 A - peak voltage seen by protected circuit during 400 W transient |
| PPPM | 400 W - surge energy handling capacity per 10/1000 μs waveform, 0.01 % duty cycle |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), critical for input rectifier protection |
| TJ max. | +175 °C - enables use in under-hood automotive environments without derating penalties |
| RθJL | 66 °C/W - thermal resistance from junction to lead, informs PCB copper pour requirements |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body; compliant with J-STD-002 solderability and JESD 201 class 2 whisker testing (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to ground or lower-potential rail in unidirectional clamp configuration |
| Cathode (banded end) | Reverse-biased protection node | Connected to protected line (e.g., 12 V supply rail); conducts when Vin > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| 400 W peak pulse power (10/1000 μs) | Protects against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot during transients, reducing stress on downstream MOSFETs or MCUs |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed automotive and industrial enclosures |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp transients above 64.1 V. Use Value: Limits voltage to ≤103 V during 400 W surges, preventing damage to 36 V-rated DC-DC converters and CAN transceivers. | Use Scenario: Analog output lines (4–20 mA) from pressure sensors in factory automation systems. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt induced lightning or EFT noise. Use Value: Clamps fast-rising transients within nanoseconds while maintaining <1.0 μA leakage at 64.1 V, preserving signal accuracy. |

IC Role / Device Role / Timing Role: First-stage protection before choke and common-mode choke filtering. Use Value: Fast response time and 66 °C/W RθJL allow effective heat dissipation into PCB copper, sustaining repeated 10/1000 μs events. |
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, 121 V VC @ 3.3 A, same 400 W rating | Higher clamping voltage (+18 V), lower IPPM (3.3 A vs. 3.9 A), surface-mount only | Select SMBJ75A for space-constrained PCBs where reflow compatibility and lower profile are prioritized over lowest possible clamping. |
| 1.5KE75A | Same DO-41 package, identical VBR/VWM/VC specs, but commercial-grade (non-AEC-Q101), no HE3 suffix | Lacks automotive qualification; not rated for extended temperature cycling or HTRB stress | Choose 1.5KE75A for cost-sensitive industrial or consumer designs where AEC-Q101 is not mandated. |
Compared with SMBJ75A and 1.5KE75A, the P4KE75CHE3/73 uniquely combines AEC-Q101 qualification, DO-41 through-hole reliability, and the lowest clamping voltage (103 V) in its VWM class - making it optimal for automotive power rail protection where thermal margin and transient fidelity are critical.

FAQ
What does the "HE3" suffix indicate in P4KE75CHE3/73?
The HE3 suffix in P4KE75CHE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. This confirms the device meets automotive-grade reliability standards including temperature cycling, highly accelerated life testing, and mechanical robustness - essential for deployment in engine control units and ADAS modules where P4KE75CHE3/73 is commonly used.
How does P4KE75CHE3/73 differ from standard P4KE75A?
The P4KE75CHE3/73 differs from generic P4KE75A by incorporating the HE3 qualification: AEC-Q101 compliance, class 2 whisker resistance, and extended validation for automotive applications. While both share identical electrical specs (VBR = 71.3–78.8 V, VC = 103 V), only P4KE75CHE3/73 carries documented qualification evidence required for Tier 1 automotive BOMs - a distinction critical when specifying P4KE75CHE3/73 in safety-critical systems.
Can P4KE75CHE3/73 be used in bidirectional configurations?
No - P4KE75CHE3/73 is strictly unidirectional, as confirmed by its "A" suffix and cathode band marking. Bidirectional variants require "CA" suffix (e.g., P4KE75CA). Using P4KE75CHE3/73 in bidirectional circuits would result in forward conduction during negative transients, causing failure. Always verify polarity: P4KE75CHE3/73 must be installed with cathode toward the protected line and anode to ground.
What is the maximum allowable lead temperature during soldering for P4KE75CHE3/73?
The maximum solder dip temperature for P4KE75CHE3/73 is 275 °C for up to 10 seconds, per JESD 22-B106. This limit applies to wave soldering or manual tinning; exceeding it risks delamination of the epoxy mold or degradation of the glass-passivated junction. For reflow, the device is not rated - P4KE75CHE3/73 is a through-hole part intended for axial or radial lead mounting, not SMT processes.
Is P4KE75CHE3/73 compatible with lead-free assembly processes?
Yes - P4KE75CHE3/73 is RoHS-compliant (per base P/N HE3 designation) and qualified for lead-free soldering per J-STD-002 and JESD 22-B102. Its matte tin-plated leads withstand peak temperatures up to 260 °C in reflow profiles, though it is a through-hole part typically processed via wave soldering. The HE3 suffix also certifies compliance with JEDEC JESD201 class 2 whisker resistance, ensuring long-term reliability in Pb-free assemblies where P4KE75CHE3/73 is deployed.
