It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5KE100C-E3/54 datasheet, 1.5KE100C-E3/54 pinout, 1.5KE100C-E3/54 application, or 1.5KE100C-E3/54 equivalent, this part delivers verified bidirectional clamping performance, RoHS-compliant matte tin leads, UL 94 V-0 molded epoxy packaging, and AEC-Q101 qualification availability - critical for automotive, industrial, and telecom surge protection design validation.
Technical Context
This TVS diode uses a glass passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating circuits without polarity constraints, supporting both line-to-line and line-to-ground transient suppression.
It complies with JEDEC standards for transient suppression and meets Underwriters Laboratories recognition (UL 497B, File E136766). The device is rated for 1000 V/min dielectric strength and supports repetitive surge duty cycles up to 0.01 % with thermal derating per Fig. 2 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), smaller SMB package (surface-mount), lower clamping voltage (144 V at 4.2 A) | Better suited for space-constrained PCBs but requires derating for >1 kV surge events | Select when board area is limited and peak surge energy remains below 600 W; verify thermal relief for continuous operation. |
| 1.5SMC100CA | Same 1500 W rating and 100 V VWM, but SMC package (surface-mount), higher thermal resistance (RθJA = 110 °C/W vs. 75 °C/W) | Requires careful layout for heatsinking; not suitable for high ambient or high-duty-cycle surges without copper pour | Choose for automated assembly compatibility if thermal management via PCB copper is feasible and lead-free reflow profile is validated. |
Compared with 1.5KE100C-E3/54, SMBJ100CA offers compactness at reduced surge capacity, while 1.5SMC100CA matches power rating but shifts thermal burden to PCB layout - making the axial 1.5KE100C-E3/54 optimal for high-reliability through-hole designs with natural convection cooling.

FAQ
What is the clamping voltage of the 1.5KE100C-E3/54 under a 10/1000 µs surge?
The 1.5KE100C-E3/54 has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5KE100C-E3/54 unidirectional or bidirectional?
The 1.5KE100C-E3/54 is a bidirectional Transient Voltage Suppressor, indicated by the "C" suffix in its part number. It provides symmetrical clamping in both polarities, eliminating the need for polarity-aware placement and enabling use in AC-coupled, floating, or differential signal paths - unlike unidirectional variants such as 1.5KE100A-E3/54.
Does the 1.5KE100C-E3/54 meet automotive qualification standards?
The base 1.5KE100C-E3/54 is commercial-grade; however, the AEC-Q101 qualified version is designated as 1.5KE100CHE3_B (with revision code "B"). That variant undergoes stress testing per AEC-Q101 including HTSL, TC, and UHAST, and is approved for use in automotive electronic control units where reliability under thermal cycling and vibration is mandatory.
