Product details
Overview
1.5KE510-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power rails and signal lines. It features a 485 V to 535 V breakdown voltage (VBR), 434 V maximum standoff voltage (VWM), 698 V clamping voltage at 2.15 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom infrastructure.
For engineers reviewing the 1.5KE510-E3/54 datasheet, 1.5KE510-E3/54 pinout, 1.5KE510-E3/54 application, or 1.5KE510-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under standardized transients, RoHS-compliant packaging details, and validated alternative parts for ESD and lightning surge protection design.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on DC-biased lines, with a 1500 W peak pulse rating defined per 10/1000 µs waveform and 0.01% duty cycle.
Thermal performance is characterized by 15.4 °C/W junction-to-lead resistance and 75 °C/W junction-to-ambient resistance. The device sustains 200 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.110 %/°C temperature coefficient of VBR, ensuring stable clamping across wide operating temperatures.
Key Specifications

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 SMAJ510A | DO-214AC (SMA) package; 510 V VWM, 680 V VC @ 2.2 A; lower PPPM (400 W). | Smaller footprint but lower surge rating; suited for space-constrained PCBs where 1500 W is not required. | Select when board area is critical and surge threat level is moderate (e.g., secondary-side signal lines). |
| ON Semiconductor 1.5SMC510A | DO-214AB (SMC) package; identical 485–535 V VBR, 434 V VWM, but 698 V VC @ 2.15 A and same 1500 W rating. | Surface-mount alternative with comparable clamping and power handling; requires SMT reflow process. | Choose for automated assembly and higher vibration resistance; verify thermal pad layout matches RθJL = 15.4 °C/W requirement. |
Compared with 1.5KE510-E3/54, SMAJ510A offers compact size at reduced surge capability, while 1.5SMC510A delivers identical protection performance in a surface-mount format-enabling trade-offs between through-hole ruggedness and SMT manufacturability without compromising clamping accuracy or thermal limits.

FAQ
What is the breakdown voltage range specified for 1.5KE510-E3/54?
The 1.5KE510-E3/54 has a guaranteed breakdown voltage (VBR) range of 485 V to 535 V at 1.0 mA test current, measured per JEDEC standard. This range ensures consistent turn-on behavior across production lots and allows proper margining above the 434 V maximum working voltage (VWM). The specification is validated at TA = 25 °C and applies to all units shipped under this part number.
Is 1.5KE510-E3/54 suitable for automotive applications?
1.5KE510-E3/54 is rated for operation from –55 °C to +175 °C and meets UL 94 V-0 flammability requirements, making it technically capable of under-hood use. However, it carries the E3 suffix indicating commercial-grade qualification-not AEC-Q101. For automotive-critical systems, Vishay's 1.5KE510AHE3_B variant (AEC-Q101 qualified) should be selected instead of 1.5KE510-E3/54.
How does the clamping voltage of 1.5KE510-E3/54 compare to its breakdown voltage?
At its rated peak pulse current of 2.15 A (10/1000 µs waveform), the 1.5KE510-E3/54 clamps to 698 V-approximately 30% above its minimum breakdown voltage of 485 V. This incremental clamping voltage (ΔVC = 213 V) reflects the device's low dynamic impedance and confirms effective energy diversion without excessive overvoltage stress on protected components.
What is the lead finish and solderability standard for 1.5KE510-E3/54?
The 1.5KE510-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. It passes JESD 201 Class 1A whisker testing, supporting reliable through-hole insertion and wave soldering at up to 275 °C for 10 seconds. The E3 suffix explicitly denotes this RoHS-compliant, commercial-grade finish.
Can 1.5KE510-E3/54 be used in bidirectional configurations?
No. 1.5KE510-E3/54 is a unidirectional TVS diode, identified by the "A" suffix (not "CA"). Bidirectional variants in the 1.5KE family are only available up to 1.5KE220CA per Vishay documentation; 1.5KE510 and higher ratings are unidirectional-only. Using 1.5KE510-E3/54 on AC or floating lines would require external circuitry to enforce polarity.
