Product details
Overview
1.5KE100CARL4 from ON Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 100 V working peak reverse voltage (VRWM), 137 V clamping voltage at 11 A peak pulse current, and 1500 W peak pulse power dissipation for 1 ms. Used in industrial power supplies and communication interfaces to protect CMOS/MOS ICs from ESD and lightning-induced transients.
For engineers reviewing the 1.5KE100CARL4 datasheet, pinout, applications, or equivalent options, this axial-leaded Zener TVS offers verified bidirectional clamping, UL 497B recognition for isolated loop protection, and Class 3 ESD immunity (>16 kV HBM), critical for robust front-end surge design.
Technical Context
The 1.5KE100CARL4 operates as a voltage-clamping device using avalanche breakdown in both polarities, with a nominal breakdown voltage of 100 V at 1 mA test current and a maximum clamping voltage of 137 V at 11 A IPP. Its low zener impedance and sub-1 ns response time enable fast suppression of transients exceeding IEC 61000-4-2 and IEC 61000-4-5 Level 4 requirements.
Thermally, it delivers 5.0 W steady-state power dissipation at 75°C lead temperature with 20°C/W junction-to-lead thermal resistance, and supports operation from −65°C to +175°C. The device is housed in a void-free, corrosion-resistant Surmetic axial package (Case 41A) with solderable leads rated for 230°C for 10 seconds.

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 peak power (600 W), surface-mount SMB package, 137 V clamping at 4.3 A | Not suitable for 1500 W surge events; requires PCB layout revision | Select only for space-constrained designs with lower surge threat profiles |
| 1.5SMC100CA | Same 1500 W rating and 100 V VRWM, but SMC (DO-214AB) surface-mount package | Lacks axial lead mechanical robustness for high-vibration environments | Prefer for automated assembly where board-level reliability testing validates mounting integrity |
Compared with SMBJ100CA and 1.5SMC100CA, the 1.5KE100CARL4 provides superior surge handling margin in through-hole applications, maintains legacy axial compatibility for field-replaceable modules, and carries UL 497B certification essential for medical and telecom infrastructure approvals.

FAQ
What is the clamping voltage of the 1.5KE100CARL4 under maximum surge conditions?
The 1.5KE100CARL4 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 11 A, measured using the standard 1 ms exponential waveform per Figure 4. This value ensures protected circuits remain below critical overvoltage thresholds during real-world surge events, and is validated across the full operating temperature range of −65°C to +175°C. The 1.5KE100CARL4 maintains this clamping performance due to its low dynamic impedance and stable avalanche characteristics.
Is the 1.5KE100CARL4 suitable for bidirectional signal line protection?
Yes, the 1.5KE100CARL4 is explicitly designed as a bidirectional TVS diode, with symmetrical electrical parameters in both polarities - including matched breakdown (95–105 V) and clamping (137 V) behavior. It is commonly deployed on AC-coupled or floating differential buses like RS-485, CAN, or isolated sensor outputs. The 1.5KE100CARL4 achieves this without polarity sensitivity, making it ideal for applications where voltage reversal cannot be guaranteed.
Does the 1.5KE100CARL4 meet UL 497B certification requirements?
Yes, the 1.5KE100CARL4 is UL Recognized under file QVGV2 to UL 497B for protector applications in isolated loop circuits. This certification covers rigorous testing including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge validation - confirming suitability for telecom, medical, and industrial isolation barriers. The 1.5KE100CARL4 shares this qualification with the full 1.5KE6.8CA–1.5KE250CA family as stated in the official ON Semiconductor documentation.
What is the maximum steady-state power dissipation for the 1.5KE100CARL4?
The 1.5KE100CARL4 is rated for 5.0 W steady-state power dissipation at a lead temperature (TL) of 75°C, with linear derating above that temperature at 20 mW/°C. This rating assumes 3/8″ lead length and defines the continuous thermal limit under DC bias conditions. Engineers must verify board-level thermal design - including copper area and airflow - to maintain TL ≤ 75°C, as exceeding this threshold reduces allowable power and impacts long-term reliability of the 1.5KE100CARL4.
How does the 1.5KE100CARL4 compare to unidirectional TVS diodes in surge protection design?
The 1.5KE100CARL4 provides symmetrical clamping for both positive and negative transients, eliminating the need for polarity-aware placement or additional components required by unidirectional devices. Unlike unidirectional TVS diodes such as 1.5KE100A, the 1.5KE100CARL4 simplifies layout in AC or floating systems and avoids forward-conduction risks during reverse surges. Its bidirectional architecture is intrinsic to the device structure, not achieved via back-to-back configuration, ensuring matched timing and identical clamping in both directions.
