Product details
Overview
5KP110HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping in power supply outputs and automotive electronics. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 5 mA, 177 V maximum clamping voltage (VC) at 28.2 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform).
For engineers reviewing the 5KP110HE3/73 datasheet, 5KP110HE3/73 pinout, 5KP110HE3/73 application, or 5KP110HE3/73 equivalent, this part is selected for robust overvoltage protection in DC power rails where AEC-Q101 qualification, low clamping ratio, and high IFSM (600 A) are critical - especially in switching power supplies, motor drive circuits, and automotive ECUs.
Technical Context
The 5KP110HE3/73 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables integration into DC-biased lines without reverse conduction concerns, and its 175 °C max junction temperature supports operation in under-hood automotive environments.
Rated for 5000 W peak pulse power with 10/1000 μs waveform and 0.01% duty cycle, it delivers stable clamping performance across -55 °C to +175 °C. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance, confirming suitability for high-reliability industrial and automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 110 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 122–135 V at 5 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 177 V at IPPM = 28.2 A - Peak voltage seen by protected circuit during 5000 W surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 5000 W (10/1000 μs) - Energy-handling capacity for lightning or inductive-switching surges; validated per JEDEC standards. |
| IFSM (Surge Current) | 600 A (8.3 ms half-sine) - Withstands repetitive line surges without degradation; critical for fuse-coordinated protection schemes. |
| TJ max | 175 °C - Enables use in high-ambient environments such as engine control units and industrial power converters. |
| Polarity | Unidirectional - Blocks reverse current; suited for DC power rail protection with defined ground reference. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110AHE3/52 | Lower PPPM (600 W), SMC package, same VWM (110 V), higher VC (183 V at 3.3 A) | Targeted for space-constrained PCBs with lower surge exposure (e.g., consumer USB ports) | Select when board area is limited and peak surge energy is ≤600 W. |
| 1.5KE110A | Same VWM (110 V) and VC (177 V), but lower PPPM (1500 W), DO-201 package, non-AEC-Q101 | Suitable for commercial-grade power supplies without automotive qualification requirements | Select for cost-sensitive industrial designs where AEC-Q101 and 5000 W rating are not mandatory. |
Compared with SMBJ110AHE3/52 and 1.5KE110A, the 5KP110HE3/73 provides 3.3× higher surge energy handling and automotive qualification - making it the only option among the three capable of surviving repeated load-dump events in ISO 16750-2 compliant ECUs without derating.

FAQ
What is the clamping voltage of the 5KP110HE3/73 under maximum surge conditions?
The 5KP110HE3/73 has a maximum clamping voltage (VC) of 177 V when subjected to its rated peak pulse current (IPPM) of 28.2 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during a 5000 W transient event.
Is the 5KP110HE3/73 suitable for automotive applications?
Yes, the 5KP110HE3/73 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power domains. Its P600 package and JESD 201 Class 2 whisker resistance further support reliability in automotive assembly and service life.
What does the "HE3" suffix indicate in 5KP110HE3/73?
The "HE3" suffix denotes that the 5KP110HE3/73 is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance requirements. The "/73" indicates packaging in 73 mm tape-and-reel format per Vishay's ordering convention.
How does the 5KP110HE3/73 compare to standard Zener diodes in surge protection?
Unlike standard Zener diodes, the 5KP110HE3/73 is engineered as a transient voltage suppressor with optimized junction geometry for high peak pulse power (5000 W), fast response (<1 ns), and low dynamic impedance. It maintains stable clamping under extreme surge conditions where Zeners would fail thermally or exhibit voltage drift.
Can the 5KP110HE3/73 be used in bidirectional configurations?
No - the 5KP110HE3/73 is unidirectional only, as confirmed in the Vishay datasheet. For bidirectional surge protection, two 5KP110HE3/73 devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., 5KP110CA) should be selected instead.
