Product details
Overview
5KP75-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 75 V stand-off voltage (VWM), and 121 V clamping voltage (VC) at 41.3 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP75-E3/54 datasheet, 5KP75-E3/54 pinout, 5KP75-E3/54 application, or 5KP75-E3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant matte tin leads, and P600 package compatibility with high-current PCB layouts requiring thermal relief.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protector in parallel with sensitive loads. Its glass-passivated P600 junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle transients induced by inductive switching or lightning surges.
It is rated for 8.0 W steady-state power dissipation on an infinite heatsink at 75 °C lead temperature and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). The cathode is marked by a color band; polarity must be observed during PCB placement to ensure proper clamping behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range. |
| VBR min/max | 83.3 V / 92.1 V at 5.0 mA - Breakdown voltage tolerance ensures reliable triggering across production lots. |
| VC @ IPPM | 121 V at 41.3 A - Clamped voltage during 5000 W transient; limits stress on downstream components. |
| IPPM | 41.3 A - Peak pulse current capability with 10/1000 μs waveform; determines surge energy handling. |
| TJ max | 175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Polarity | Unidirectional - Requires correct orientation; blocks reverse leakage below VWM, clamps only in reverse avalanche. |

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 | Lower peak power (600 W), SMC package, 100 V clamping at 6.2 A | Not suitable for 5000 W load dump; limited to low-energy signal-line protection | Select only for space-constrained PCBs where surge energy is ≤100 mJ. |
| 1.5KE75A | Same P600 package, 1500 W rating, 120 V clamping at 12.5 A | Lacks AEC-Q101 qualification; not validated for automotive temperature cycling or humidity testing | Acceptable for industrial controls but not for automotive OEM designs requiring qualification evidence. |
Compared with SMBJ75A and 1.5KE75A, the 5KP75-E3/54 delivers 3.3× higher surge energy capacity and certified automotive reliability-critical when protecting 75 V power rails exposed to ISO 16750-2 transients or repetitive motor-switching events.

FAQ
What is the clamping voltage of the 5KP75-E3/54 under maximum rated surge current?
The 5KP75-E3/54 clamps to 121 V at its rated peak pulse current of 41.3 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and guarantees consistent overvoltage limiting during standardized surge events. The 5KP75-E3/54 maintains this clamping performance across its qualified operating temperature range of –55 °C to +175 °C.
Is the 5KP75-E3/54 suitable for automotive applications?
Yes, the 5KP75-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, matte tin leads, and P600 package-meets requirements for temperature cycling, high-temperature reverse bias, and mechanical shock. The 5KP75-E3/54 is deployed in engine control units, body electronics, and ADAS power domains where ISO 7637-2 compliance is mandatory.
What does the "E3/54" suffix indicate in 5KP75-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade termination per JESD201 Class 1A whisker testing; "/54" specifies the preferred packaging code for 13-inch paper tape and reel, with 800 units per reel. This matches Vishay's ordering convention in Document Number 88308 and confirms full traceability to Vishay General Semiconductor's production lot control system.
How does the 5KP75-E3/54 differ from bidirectional TVS diodes?
The 5KP75-E3/54 is unidirectional and functions only as a reverse-biased avalanche clamp-blocking conduction below 75 V in reverse and conducting only during overvoltage events. Bidirectional variants (e.g., 5KP75CA) conduct in both directions and are used where AC line or data-line symmetry demands dual-polarity protection. The 5KP75-E3/54 is not interchangeable with bidirectional types without circuit redesign.
Can the 5KP75-E3/54 replace a crowbar circuit in power supplies?
Yes-the 5KP75-E3/54 was explicitly designed to replace crowbar circuits in switching power supply outputs. Unlike crowbars that short the rail and require fuse replacement, the 5KP75-E3/54 clamps transient energy while allowing upstream breakers to trip and reset. Its 5000 W rating and thermal robustness enable repeated operation without degradation, making the 5KP75-E3/54 ideal for resettable overvoltage protection in 75 V systems.
