Product details
Overview
5KP110-E3/73 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), 110 V stand-off voltage (VWM), and 177 V maximum clamping voltage (VC) at 28.2 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP110-E3/73 datasheet, 5KP110-E3/73 pinout, 5KP110-E3/73 application, or 5KP110-E3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events-such as inductive load switching or lightning-induced surges-and conducts excess energy to ground while limiting downstream voltage to ≤177 V. Its glass-passivated P600 chip junction enables fast response time (<1 ns) and stable breakdown behavior under repetitive 0.01% duty cycle pulses.
The device is rated for 5000 W peak pulse power with 10/1000 μs waveform, 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge current (8.3 ms half-sine). Its 0.112 %/°C VBR temperature coefficient ensures predictable clamping across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before conduction begins; defines circuit's normal operating margin. |
| VBR @ IT = 5 mA | 122–135 V - Breakdown voltage range at test current; determines precise turn-on threshold under surge conditions. |
| VC @ IPPM = 28.2 A | 177 V - Clamped voltage during 10/1000 μs surge; limits stress on protected downstream components. |
| PPPM | 5000 W - Peak pulse power handling capability; supports high-energy transients without failure. |
| IFSM | 600 A - Non-repetitive forward surge current rating (8.3 ms); validates robustness against short-duration overcurrent events. |
| TJ Range | -55 °C to +175 °C - Extended thermal operating envelope suitable for under-hood automotive and industrial environments. |
| Polarity | Unidirectional - Cathode marked by color band; used where reverse-biased DC blocking is required. |
Pinout & Package
5KP110-E3/73 uses the P600 axial-leaded package: molded epoxy body over glass-passivated junction, UL 94 V-0 rated, with matte tin-plated leads solderable per J-STD-002. Polarity is indicated by a cathode band; terminals are anode and cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side reference; completes clamping path during transient events. |
| Cathode | Current exit point during forward conduction; marked by color band | Connected to protected line (e.g., power rail or signal); defines direction of clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
| 5000 W peak pulse power (10/1000 μs) | Enables protection against high-energy transients common in 12 V/24 V vehicle electrical systems and industrial motor drives. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving clamping precision and system-level ESD/lightning resilience. |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Ensures long-term solder joint integrity and compliance with global environmental and reliability standards. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Lower peak pulse power (600 W), SMC package, same VWM/VC ratings but reduced IPPM (53.3 A → 13.3 A). | Suitable for space-constrained PCBs with lower surge energy requirements (e.g., consumer USB ports). | Select SMBJ110A only when board area is critical and surge threat level is ≤600 W. |
| 1.5KE110A | Same VWM (110 V), lower PPPM (1500 W), DO-201 package, higher VC (187 V), and no AEC-Q101 qualification. | Acceptable for cost-sensitive industrial controls where automotive qualification is not mandated. | Choose 1.5KE110A for legacy designs requiring DO-201 footprint compatibility and moderate surge immunity. |
Compared with SMBJ110A and 1.5KE110A, the 5KP110-E3/73 delivers 3.3× higher peak pulse power than SMBJ110A and 3.3× higher than 1.5KE110A, maintains AEC-Q101 qualification, and offers superior thermal dissipation via P600 package-making it optimal for high-reliability automotive and heavy-duty industrial applications.

FAQ
What is the clamping voltage of the 5KP110-E3/73 under standard surge conditions?
The 5KP110-E3/73 has a maximum clamping voltage (VC) of 177 V at 28.2 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC-standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance remains stable across its full operating temperature range (-55 °C to +175 °C).
Is the 5KP110-E3/73 suitable for automotive applications?
Yes, the 5KP110-E3/73 is AEC-Q101 qualified and explicitly designed for automotive use-including engine control units, body electronics, and powertrain modules. Its P600 package provides superior thermal dissipation, and its 175 °C maximum junction temperature supports under-hood deployment. The "HE3" variant is fully AEC-Q101 certified; the "E3" suffix indicates RoHS-compliant commercial grade with identical electrical specs.
What does the "-E3/73" suffix indicate in 5KP110-E3/73?
The "E3" denotes RoHS-compliant matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/73" specifies the preferred packaging option: 73 = 800 pcs per 13-inch paper tape and reel. This ordering code aligns with Vishay's standard P600 packaging configuration and ensures compatibility with automated SMT placement equipment when used with appropriate lead-forming tooling.
How does the 5KP110-E3/73 compare to standard 1.5KE series TVS diodes?
The 5KP110-E3/73 delivers 5000 W peak pulse power-more than three times the 1500 W rating of the 1.5KE110A-while maintaining comparable VWM (110 V) and tighter VC (177 V vs. 187 V). Its P600 package offers significantly better thermal performance than the DO-201 package of the 1.5KE series, supporting higher sustained surge repetition rates in demanding applications.
Can the 5KP110-E3/73 be used in bidirectional configurations?
No, the 5KP110-E3/73 is unidirectional only, as confirmed in Vishay's datasheet. It features a single cathode band and is intended for DC-biased lines where clamping is required in one polarity only. For bidirectional protection, two 5KP110-E3/73 devices must be connected in series opposition-or a dedicated bidirectional part such as 5KP110CA should be selected instead.
