Product details
Overview
5KP120A-E3/54 from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features a 120 V stand-off voltage (VWM), 133–147 V breakdown voltage (VBR) at 5 mA, 193 V clamping voltage (VC) at 25.9 A peak pulse current, and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the 5KP120A-E3/54 datasheet, 5KP120A-E3/54 pinout, 5KP120A-E3/54 application, or 5KP120A-E3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity compatibility with DC bus protection, AEC-Q101 qualification for automotive use, and P600 thermal derating behavior at elevated ambient temperatures.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective clamping of lightning- and switching-induced transients on power supplies and motor drives. Its unidirectional structure provides reverse-biased surge suppression while allowing forward conduction during fault conditions.
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 8.0 W steady-state power dissipation on an infinite heatsink at TL = 75 °C. Thermal derating begins above TA = 25 °C per Figure 2, with full power capability maintained up to TJ = 175 °C.

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 SMAJ120A | Lower PPPM (400 W), smaller SMA package (1.5 W PD), 193 V VC at 12.3 A; not AEC-Q101 qualified | Suitable only for low-energy signal-line or auxiliary rail protection; insufficient for primary DC bus clamping | Select 5KP120A-E3/54 when 5000 W surge handling and automotive qualification are required; SMAJ120A is a space-constrained alternative for secondary circuits. |
| ON Semiconductor 1.5KE120A | Same P600 package, 5000 W rating, but lower TJ max (175 °C same), higher VC (200 V), and no AEC-Q101 qualification | Acceptable for industrial/commercial power supplies but not approved for automotive safety-critical modules | Choose 5KP120A-E3/54 for AEC-Q101-compliant designs; 1.5KE120A may be used where automotive qualification is not mandated and 7 V higher clamping is acceptable. |
Compared with SMAJ120A and 1.5KE120A, the 5KP120A-E3/54 delivers identical 5000 W surge capacity and superior automotive qualification, while offering tighter VBR tolerance (133–147 V vs. ±10 %) and lower clamping voltage than the 1.5KE120A-critical for protecting marginally rated 200 V components.

FAQ
What is the clamping voltage of the 5KP120A-E3/54 under a 10/1000 μs surge?
The 5KP120A-E3/54 has a maximum clamping voltage (VC) of 193 V at 25.9 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the upper limit of voltage seen by downstream circuitry during a standardized surge event. The 5KP120A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the 5KP120A-E3/54 suitable for automotive applications?
Yes, the 5KP120A-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. Its P600 package, 175 °C maximum junction temperature, and unidirectional configuration make it appropriate for under-hood power distribution modules, battery management systems, and motor control units where transient immunity is critical. The 5KP120A-E3/54 meets automotive reliability requirements without derating.
What does the "E3/54" suffix indicate in 5KP120A-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "54" is the preferred package code indicating 13-inch paper tape and reel packaging with a base quantity of 800 units. This ordering format ensures traceability, solderability per J-STD-002, and compatibility with automated SMT placement equipment. The 5KP120A-E3/54 is supplied in this industry-standard reel format.
How does the 5KP120A-E3/54 differ from bidirectional TVS diodes?
The 5KP120A-E3/54 is unidirectional and functions as a reverse-biased Zener-like clamp during overvoltage events, while conducting forward current during extreme faults. Unlike bidirectional TVS diodes-which protect both polarities symmetrically-the 5KP120A-E3/54 is intended for DC systems where polarity is fixed and forward conduction is acceptable. Its design avoids unnecessary capacitance and leakage in AC-coupled signal paths. The 5KP120A-E3/54 is not rated for AC line protection.
What thermal considerations apply when mounting the 5KP120A-E3/54?
The 5KP120A-E3/54 dissipates up to 8.0 W on an infinite heatsink at TL = 75 °C, but derates linearly above TA = 25 °C per Figure 2 in the datasheet. For reliable operation, minimum copper pour area of 250 mm² per lead on 2 oz. FR-4 is recommended; thermal vias under the cathode pad improve heat transfer. The 5KP120A-E3/54 must avoid proximity to other heat sources exceeding 85 °C ambient to maintain full surge capability.
