Product details
Overview
5KP75AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 75 V stand-off voltage (VWM), 83.3–92.1 V breakdown voltage (VBR) at 5 mA, 121 V maximum clamping voltage (VC) at 41.3 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP75AHE3_A/C datasheet, 5KP75AHE3_A/C pinout, 5KP75AHE3_A/C application, or 5KP75AHE3_A/C equivalent, key selection criteria include clamping performance under 41.3 A surge, unidirectional polarity confirmation, AEC-Q101 qualification status, thermal derating above 25 °C, and compatibility with P600 PCB footprints and 275 °C solder dip profiles.
Technical Context
This device operates as a voltage-clamping avalanche diode, triggered when reverse voltage exceeds its breakdown threshold (VBR), diverting transient energy to ground while limiting downstream voltage to ≤121 V. Its P600 glass-passivated junction enables robust 5000 W surge handling with low incremental surge resistance and sub-nanosecond response time.
Rated for -55 °C to +175 °C junction temperature, it supports automotive-grade reliability per AEC-Q101, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements in its molded epoxy body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin. |
| VBR (min/max) | 83.3 V / 92.1 V at 5 mA - guaranteed avalanche initiation range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 121 V at 41.3 A - clamped voltage during full 5000 W transient; determines protected circuit's peak overvoltage stress. |
| PPPM | 5000 W - peak pulse power with 10/1000 μs waveform; validates capability to absorb lightning or inductive-switching surges. |
| TJ max. | +175 °C - maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| IFSM | 500 A - non-repetitive forward surge current (8.3 ms half-sine); supports crowbar-style fault clearing without device failure. |
| Polarity | Unidirectional - cathode marked by color band; suitable for DC-biased protection where reverse conduction must be blocked. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated chip junction; 0.360" × 0.340" body (9.1 mm × 8.6 mm), 0.375" lead length (9.5 mm), UL 94 V-0 rated, RoHS-compliant matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line's low-side or ground reference; completes clamping loop during overvoltage events. |
| Cathode | Reverse-biased avalanche node | Marked by color band; connected to protected line's high-side (e.g., 75 V rail); conducts when Vreverse > VBR. |
Key Features
| Feature | Design Value |

| Motor Drive Gate Driver Protection | Automotive Sensor Signal Line Protection |
|
Use Scenario: Shielding high-side gate drivers in 48 V BLDC inverters from shoot-through-induced voltage spikes. IC Role / Device Role / Timing Role: Mounted across driver supply pins (VDD-to-GND) to clamp fast-rising transients (<1 ns rise time). Use Value: Sub-nanosecond response ensures clamping initiates before gate oxide breakdown in 100 V SiC drivers. |
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control modules from ESD and cable discharge. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at connector interface to shunt transients before signal conditioning ICs. Use Value: 2 µA max leakage at 75 V preserves signal integrity in microamp-level sensor bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ75A | Same 75 V VWM, but 400 W PPPM (SMA package); lower surge capacity and thermal mass. | Restricted to low-energy transients (IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select only for space-constrained PCBs where 5000 W surge immunity is not required. |
| ON Semiconductor 1.5KE75A | Same VWM and P600 package, but 1500 W PPPM and higher VC (129 V); lower surge rating and looser clamping. | Marginally adequate for 12 V automotive; fails IEC 61000-4-5 Level 3 without derating. | Use only if cost sensitivity outweighs surge margin; verify clamping headroom with worst-case 100 V transients. |
Compared with SMAJ75A and 1.5KE75A, the 5KP75AHE3_A/C delivers 3.3× higher peak pulse power and tighter clamping (121 V vs. ≥129 V), making it the sole option among the three qualified for AEC-Q101 and capable of surviving full load dump without coordination with fuses or breakers.

FAQ
What is the clamping voltage of the 5KP75AHE3_A/C at its rated peak pulse current?
The 5KP75AHE3_A/C has a maximum clamping voltage (VC) of 121 V when subjected to its rated peak pulse current (IPPM) of 41.3 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry will not experience more than 121 V during a full 5000 W transient event, provided layout minimizes parasitic inductance.
Is the 5KP75AHE3_A/C suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KP75AHE3_A/C is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 16-Mar-2023 (Document Number: 88308). The HE3 suffix denotes AEC-Q101 compliance, and the device undergoes stress testing including high-temperature reverse bias, high-temperature operating life, and temperature cycling - making it appropriate for engine control units and ADAS modules.
How does the 5KP75AHE3_A/C differ from the standard 5KP75A variant?
The 5KP75AHE3_A/C differs from the base 5KP75A by its HE3 suffix, indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the standard 5KP75A (E3 suffix) is commercial-grade only. Both share identical electrical specs and P600 packaging, but only the HE3 version is approved for automotive under-hood deployment per industry reliability standards.
What is the maximum operating temperature for the 5KP75AHE3_A/C junction?
The 5KP75AHE3_A/C has a maximum junction temperature (TJ max.) of +175 °C, as specified in the Vishay datasheet. This allows reliable operation in high-ambient environments such as automotive engine compartments or industrial motor drives, provided thermal design accounts for power dissipation derating above 25 °C per Figure 2 in the datasheet.
Can the 5KP75AHE3_A/C be used in bidirectional protection configurations?
No, the 5KP75AHE3_A/C is unidirectional only, as clearly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It contains a single PN junction optimized for reverse-bias clamping; bidirectional protection requires either a dedicated bidirectional TVS (e.g., 5KP75CA) or back-to-back unidirectional devices - neither of which applies to the 5KP75AHE3_A/C.
