Product details
Overview
5KP100-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 100 V standoff voltage (VWM), 111–123 V breakdown range (VBR), 162 V clamping voltage at 30.9 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is widely deployed in automotive power supply outputs and industrial motor drive control circuits.
For engineers reviewing the 5KP100-E3/73 datasheet, 5KP100-E3/73 pinout, 5KP100-E3/73 application, or 5KP100-E3/73 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under repetitive transients, AEC-Q101 qualification status, and RoHS-compliant packaging details - all critical for overvoltage protection design validation and BOM selection.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during fast-rising transients (response time <1 ps), leveraging a glass-passivated P600 junction to sustain 5000 W peak pulse power without degradation. Its unidirectional polarity enables integration into DC-biased rails where reverse conduction must be blocked until clamping threshold is exceeded.
Thermal performance is defined by 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C and 175 °C maximum junction temperature. Derating curves (Fig. 2 & Fig. 5) confirm usable operation up to 150 °C ambient when mounted on ≥1 in² copper area, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before leakage exceeds 2 μA; sets upper limit for safe DC rail placement. |
| VBR @ IT = 5 mA | 111–123 V - Breakdown voltage range defining clamping onset; ensures reliable triggering above nominal 100 V system voltage. |
| VC @ IPPM = 30.9 A | 162 V - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to ≤162 V under worst-case 5 kW transient. |
| PPPM | 5000 W - Peak pulse power rating per JEDEC standard; validates capability to absorb lightning-induced surges (IEC 61000-4-5 Level 4). |
| TJ max. | 175 °C - Maximum junction temperature; supports operation in engine-control units and industrial inverters with minimal heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower peak power (600 W), smaller SMB package, 111–123 V VBR, 162 V VC at 3.7 A | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy signal-line or secondary-side protection | Select when space-constrained layouts require SMT mounting and surge energy is ≤100 mJ. |
| 1.5KE100A | Same 100 V VWM, but 1500 W PPPM, DO-201 package, 162 V VC at 9.2 A, no AEC-Q101 qualification | Lacks automotive qualification and thermal robustness for under-hood use; higher thermal resistance than P600 | Choose for cost-sensitive industrial power supplies where AEC-Q101 is not mandated and PCB layout allows axial-leaded devices. |
Compared with SMBJ100A and 1.5KE100A, the 5KP100-E3/73 delivers 3.3× higher pulse power handling and automotive-grade reliability in a thermally optimized P600 package - making it the sole choice for primary-side 100 V rail protection in harsh-environment applications requiring sustained surge immunity.

FAQ
What is the clamping voltage of the 5KP100-E3/73 under a 10/1000 μs surge?
The 5KP100-E3/73 clamps to a maximum of 162 V when subjected to its rated peak pulse current of 30.9 A using the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees predictable overvoltage limiting for downstream 100 V-rated components. The 5KP100-E3/73 achieves this clamping with low incremental resistance, minimizing voltage overshoot during fast transients.
Is the 5KP100-E3/73 qualified for automotive applications?
Yes, the 5KP100-E3/73 is AEC-Q101 qualified, having passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD. Its P600 package and 175 °C maximum junction temperature support deployment in engine control units, body control modules, and ADAS power supplies. The 5KP100-E3/73 meets automotive reliability requirements without derating in most under-hood thermal environments.
How does the 5KP100-E3/73 differ from the 1.5KE100A in practical design use?
The 5KP100-E3/73 offers 5000 W peak pulse power versus 1500 W for the 1.5KE100A, enabling protection against higher-energy surges like ISO 7637-2 Pulse 5a. Its P600 package provides superior thermal dissipation and AEC-Q101 qualification - unlike the DO-201-packaged 1.5KE100A. In designs requiring automotive compliance or >2 kA surge handling, the 5KP100-E3/73 is mandatory; the 1.5KE100A suits cost-driven non-automotive applications.
What is the standoff voltage (VWM) and why is it critical for 5KP100-E3/73 placement?
The 5KP100-E3/73 has a 100 V standoff voltage (VWM), meaning it remains non-conductive with ≤2 μA leakage up to 100 V DC. This parameter dictates safe placement on 100 V nominal rails - such as automotive 24 V systems with 100 V load-dump margins or industrial 96 V DC links. Exceeding VWM risks premature conduction and thermal runaway; the 5KP100-E3/73's precise 100 V rating ensures optimal margin between normal operation and clamping onset.
Can the 5KP100-E3/73 replace a MOV in a 100 V power supply design?
Yes, the 5KP100-E3/73 can replace MOVs in 100 V DC applications where faster response (<1 ps vs. ~25 ns), tighter clamping tolerance (±5 % VBR vs. ±10–20 %), and no wear-out mechanism are required. Unlike MOVs, the 5KP100-E3/73 exhibits no degradation after repeated surges and maintains stable VC. However, its 5000 W rating applies only to short pulses - for sustained overvoltage, supplemental crowbar or shutdown circuitry remains necessary. The 5KP100-E3/73 is ideal for transient-only protection where reliability and precision matter.
