Product details
Overview
1.5KE100CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V breakdown voltage (VBR = 95–105 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 137 V at 10.9 A, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 1.5KE100CA-E3/54 datasheet, 1.5KE100CA-E3/54 pinout, 1.5KE100CA-E3/54 application, or 1.5KE100CA-E3/54 equivalent, this device delivers verified bidirectional clamping performance, RoHS-compliant packaging (E3 suffix), and UL 94 V-0 molded epoxy construction - critical for ESD and lightning surge hardening in high-reliability DC bus and I/O line designs.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity concerns.
It sustains 1500 W peak pulse power under standardized 10/1000 µs waveform conditions with 0.01% duty cycle, and derates linearly above 25 °C ambient per Fig. 2 - enabling thermal-aware layout in compact power modules and motor drive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95 V / 105 V - ensures reliable conduction onset within ±5% of nominal rating under 1 mA test current |
| VWM | 85.5 V - maximum continuous working voltage before leakage exceeds 1 µA; defines safe operating margin below breakdown |
| VC @ IPPM | 137 V - clamped voltage at 10.9 A peak pulse current; determines protected circuit's maximum transient stress level |
| PPPM | 1500 W - peak pulse power handling for 10/1000 µs transients; supports IEC 61000-4-5 Level 4 surge immunity |
| IPPM | 10.9 A - maximum non-repetitive surge current; sets minimum trace width and fuse coordination requirements |
| TJ max. | +175 °C - extended junction temperature rating enables use in under-hood automotive and industrial power converters |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length; compatible with wave soldering (275 °C, 10 s) |
Pinout & Package
1.5KE100CA-E3/54 uses a bidirectional axial-leaded DO-201AD package (Case Style 1.5KE). No polarity marking is present - both terminals are functionally identical for symmetrical transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (both ends) | Bidirectional clamping node | Interchangeable terminals; connects across protected line (e.g., between VCC and GND or differential pair) without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs |
| Sub-nanosecond response time | Clamps transients before sensitive downstream components (e.g., gate drivers) experience overvoltage damage |
| UL 94 V-0 epoxy molding | Provides flame-retardant mechanical encapsulation suitable for safety-critical end equipment certifications |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards for high-volume manufacturing |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed across main power rail upstream of DC-DC converters. Use Value: Limits rail voltage to ≤137 V during 100 V/10.9 A surges, preventing latch-up or gate oxide rupture in downstream PMICs and microcontrollers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable-induced transients in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS connected between signal line and ground on PCB edge connectors. Use Value: Clamps ±15 kV HBM ESD events within <1 ns while adding <0.5 pF parasitic capacitance - preserving signal integrity up to 1 MHz bandwidth. |
| Telecom DC Power Feeds | Motor Drive Control Signal Lines |
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras) against induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary-level TVS mounted at board entry point, coordinated with secondary-stage MOVs. Use Value: Absorbs 1500 W surge energy without degradation, maintaining VWM = 85.5 V to avoid false triggering during normal 48 V ±10% operation. |
Use Scenario: Protecting isolated gate driver inputs (e.g., ISO5852S) from fast-rising transients caused by IGBT switching noise. IC Role / Device Role / Timing Role: Bidirectional clamp across logic-level control lines referenced to floating gate driver ground. Use Value: Suppresses common-mode spikes up to 137 V without polarity sensitivity - eliminating need for dual unidirectional devices or external biasing. |
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), VC = 165 V @ 3.6 A | Preferred for space-constrained PCBs where 1500 W rating is not required; lacks axial-leaded mechanical robustness | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5KE100A-E3/54 | Unidirectional variant; same VBR, VC, and PPPM, but requires cathode orientation and has higher forward voltage (VF = 3.5 V) | Used only in DC-coupled, polarity-defined rails (e.g., single-supply microcontroller I/O); unsuitable for AC or floating lines | Choose only if system topology mandates unidirectional clamping and polarity is fixed and known |
Compared with SMBJ100CA and 1.5KE100A-E3/54, the 1.5KE100CA-E3/54 uniquely combines bidirectional symmetry, 1500 W capability, and through-hole mechanical stability - making it optimal for high-energy, polarity-agnostic protection in industrial power entry and automotive junction boxes.

FAQ
What is the breakdown voltage range for 1.5KE100CA-E3/54?
The 1.5KE100CA-E3/54 has a guaranteed breakdown voltage range of 95 V to 105 V at 1 mA test current (VBR min/max), per Vishay Document 88301. This 10 V window ensures consistent clamping onset across production lots and supports design margining for 100 V nominal systems. The value is measured under standard JEDEC conditions and applies equally in both directions due to its bidirectional construction.
Is 1.5KE100CA-E3/54 RoHS compliant and qualified for automotive use?
Yes, the 1.5KE100CA-E3/54 carries the E3 suffix, confirming RoHS compliance, matte tin-plated leads, and JESD 201 Class 1A whisker resistance. While the base 1.5KE100CA-E3/54 is commercial-grade, AEC-Q101 qualification is available in the HE3 variant (e.g., 1.5KE100CAHE3_B). For automotive applications requiring AEC-Q101, specify the HE3 version - the 1.5KE100CA-E3/54 itself meets all electrical and mechanical specs but lacks formal automotive qualification.
How does the clamping voltage of 1.5KE100CA-E3/54 compare to its breakdown voltage?
The 1.5KE100CA-E3/54 clamps at 137 V when subjected to its rated 10.9 A peak pulse current (IPPM), which is 32–45 V above its VBR range (95–105 V). This 37 V differential (VC – VBR) reflects low incremental surge resistance and defines the maximum overvoltage stress imposed on protected circuitry. Designers must ensure downstream components tolerate this 137 V ceiling during worst-case transients.
Can 1.5KE100CA-E3/54 be used in AC line protection?
Yes - the bidirectional nature of 1.5KE100CA-E3/54 makes it suitable for AC-coupled or floating signal paths, including low-voltage AC sensing lines and isolated communication interfaces. However, it is not rated for direct connection to mains AC (e.g., 120/230 VAC) due to insufficient VWM (85.5 V) and lack of reinforced insulation. Use only on secondary-side AC signals ≤80 V RMS, with appropriate current-limiting impedance upstream.
What is the thermal resistance and derating behavior of 1.5KE100CA-E3/54?
The 1.5KE100CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Its 1500 W peak pulse power must be derated linearly above 25 °C ambient per Figure 2 in Vishay Doc 88301 - e.g., at 75 °C ambient, maximum allowable PPPM drops to ~1125 W. Continuous power dissipation remains limited to 6.5 W even with infinite heatsinking at TL = 75 °C.
