Product details
Overview
5KP110A-E3/54 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 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 5 mA, 177 V maximum clamping voltage at 28.2 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 5KP110A-E3/54 datasheet, 5KP110A-E3/54 pinout, 5KP110A-E3/54 application, or 5KP110A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity requirement, P600 thermal derating above 25 °C, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients, conducting only when reverse voltage exceeds its VBR threshold. Its glass-passivated P600 junction delivers low incremental surge resistance and sub-nanosecond response time, enabling effective suppression of lightning-induced surges and inductive switching spikes.
The device is rated for 5000 W peak pulse power (10/1000 μs), 500 A non-repetitive forward surge current (8.3 ms half-sine), and operates across -55 °C to +175 °C junction temperature range. It is RoHS-compliant (E3 suffix), meets JESD 201 Class 1A whisker test, and is qualified to AEC-Q101 for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 110 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below protected circuit's max rating. |
| VBR (Breakdown Voltage) | 122–135 V at 5 mA - Confirmed breakdown range defining turn-on threshold under standardized test conditions. |
| VC (Clamping Voltage) | 177 V at IPPM = 28.2 A - Peak voltage seen by downstream circuit during worst-case 10/1000 μs surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 5000 W - Sustained energy absorption capability per JEDEC-standard 10/1000 μs waveform at TA = 25 °C. |
| IFSM (Surge Current) | 500 A - Non-repetitive forward surge rating (8.3 ms half-sine), supporting fuse/breaker coordination in overvoltage events. |
| TJ max. | +175 °C - Maximum junction temperature enabling operation in under-hood automotive or high-ambient industrial environments. |
| Polarity | Unidirectional - Cathode marked by color band; suitable for DC-biased rail protection, not AC line applications. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated junction, UL 94 V-0 rated, matte tin-plated leads solderable per J-STD-002. Dimensions: 9.5 mm × 9.1 mm × 1.32 mm (L × W × H), lead spacing 9.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., ground or return path); conducts during forward surge events. |
| Cathode | Reverse-biased clamping terminal | Marked by color band; connected to protected line (e.g., 12 V rail); initiates clamping when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use including engine control units and body modules requiring high-reliability surge immunity. |
| 5000 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV) surges without cascaded TVS or external current limiting. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage stress on downstream components - e.g., 177 V clamp vs. 122 V min VBR provides tight protection window. |
| P600 thermal mass | Supports 8.0 W steady-state dissipation on infinite heatsink at TL = 75 °C, allowing robust thermal design in compact power supply layouts. |
| 10/1000 μs waveform compliance | Meets industry-standard lightning surge test profile per REA and IEC 61643-31, ensuring predictable field performance. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |

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 SMAJ110A | Lower peak power (400 W), SMA package (smaller thermal mass), 177 V VC at 15.1 A IPPM | Not suitable for 5000 W surge events; limited to board-level ESD or low-energy transients | Select only for space-constrained designs where full 5KP-level energy handling is unnecessary. |
| ON Semiconductor 1.5KE110A | Same 110 V VWM and unidirectional polarity, but 1500 W PPPM rating and DO-201 package | Lacks AEC-Q101 qualification and cannot sustain repeated 5000 W pulses without degradation | Acceptable for cost-sensitive industrial applications without automotive qualification requirements. |

FAQ
What is the clamping voltage of the 5KP110A-E3/54 under a 10/1000 μs surge?
The 5KP110A-E3/54 has a maximum clamping voltage (VC) of 177 V when subjected to its rated peak pulse current 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 surge events - critical for ensuring compatibility with downstream ICs rated for ≤200 V absolute maximum.
Is the 5KP110A-E3/54 suitable for automotive applications?
Yes, the 5KP110A-E3/54 is AEC-Q101 qualified and explicitly designed for automotive use cases including engine control units, body electronics, and infotainment power supplies. Its P600 package, -55 °C to +175 °C operating range, and compliance with ISO 7637-2 load dump testing make it appropriate for under-hood and chassis-mounted applications requiring certified reliability.
What does the "E3/54" suffix indicate in 5KP110A-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 13-inch paper tape and reel containing 800 units. This ordering format ensures traceability, automated assembly compatibility, and adherence to Vishay's standard logistics configuration for the P600 device family.
How does the 5KP110A-E3/54 differ from bidirectional TVS diodes?
The 5KP110A-E3/54 is unidirectional - it clamps only in reverse bias and conducts forward current like a standard diode. Unlike bidirectional variants, it must be oriented with cathode toward the protected line and anode to ground. This configuration provides tighter VBR control and lower leakage (<2 µA at 110 V), making it ideal for DC power rail protection where polarity is fixed.
Can the 5KP110A-E3/54 replace a 5KP100A in a 12 V system?
No - the 5KP110A-E3/54 has a 110 V stand-off voltage (VWM), which is too high for direct substitution in a 12 V system where 5KP100A (100 V VWM) is typically used. Using 5KP110A-E3/54 would reduce protection margin and risk failure to clamp during lower-voltage transients. Always match VWM to the nominal rail voltage plus safety margin (e.g., 100 V for 12 V systems with load dump).
