Product details
Overview
1.5KE100CA/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 100 V breakdown voltage (VBR min/max = 95.0–105 V), 85.5 V standoff voltage (VWM), 137 V clamping voltage (VC) at 10.9 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in industrial and automotive systems.
For engineers reviewing the 1.5KE100CA/54 datasheet, 1.5KE100CA/54 pinout, 1.5KE100CA/54 application, or 1.5KE100CA/54 equivalent, this device delivers verified bidirectional clamping performance with low incremental surge resistance, fast sub-nanosecond response, and AEC-Q101 qualification options - critical for robust overvoltage design in DC power rails, CAN bus interfaces, and automotive body control modules.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for bidirectional transient suppression without polarity marking. Its clamping action responds within <1 ns in both directions, maintaining symmetrical VBR tolerance (±5%) and low dynamic impedance under 10/1000 µs surges.
It is rated for 1500 W peak pulse power with 0.01% duty cycle, derates linearly above 25 °C ambient per Fig. 2, and exhibits 75 °C/W junction-to-ambient thermal resistance. The device supports 10.9 A peak pulse current (IPPM) while limiting voltage to 137 V - enabling reliable protection of 100 V-rated downstream components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - ensures consistent breakdown initiation across production lots; guarantees clamping begins no later than 105 V in either polarity. |
| VWM | 85.5 V - maximum continuous reverse operating voltage; allows safe placement on 72–80 V DC rails (e.g., 24 V automotive systems with 3× ripple). |
| VC @ IPPM | 137 V - clamping voltage at 10.9 A peak pulse; limits stress on protected ICs to ≤137 V during 10/1000 µs transients. |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform; sustains single-event surges up to 1.5 kW without failure. |
| IPPM | 10.9 A - peak pulse current capacity; defines maximum surge energy (≈1.5 J) the device can absorb per event. |
| TJ range | –55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package (0.375" lead length); compatible with through-hole PCB assembly and manual rework. |
Pinout & Package
1.5KE100CA/54 is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package with no polarity marking - consistent with its bidirectional function. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and rated for solder dip at 275 °C max for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional terminal pair | Either lead serves as anode or cathode depending on transient polarity; no color band or marking required. |
| Lead 1 / Lead 2 | Current path interface | Leads connect directly to PCB traces or wire harnesses; thermal path relies on 0.375" (9.5 mm) lead length for RθJL = 15.4 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR and low leakage (<1 µA at VWM) over lifetime and temperature cycling. |
| 1500 W peak pulse rating (10/1000 µs) | Supports IEC 61000-4-5 Level 4 (4 kV line-earth) surge testing when properly coordinated with series impedance. |
| Sub-nanosecond response time | Clamps transients before sensitive logic or analog circuitry experiences overvoltage - critical for protecting CAN transceivers and MCU I/O. |
| AEC-Q101 qualified variants available | HE3 suffix versions meet automotive reliability standards for under-hood and chassis applications (e.g., 1.5KE100CAHE3_B). |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical encapsulation suitable for safety-critical industrial and transportation end equipment. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in body control modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between VBAT and GND, absorbing >100 A surge currents via low-impedance path. Use Value: Limits rail voltage to ≤137 V during 100 V/100 ms load dump events, preventing damage to PMICs and microcontrollers rated for 120 V absolute max. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in factory automation PLC I/O modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) shunt protector on differential signal pairs, responding in <1 ns to preserve signal integrity. Use Value: Clamps ±8 kV contact ESD (IEC 61000-4-2) to <150 V, avoiding latch-up or parametric shift in precision ADC front-ends. |
| Telecom DC Feeder Protection | Renewable Energy Inverter DC Link |
Use Scenario: Safeguarding PoE-powered remote radios and base station controllers connected to long outdoor copper runs susceptible to induced lightning. IC Role / Device Role / Timing Role: Primary surge arrestor on 48 V DC input, coordinated with upstream MOVs and downstream filtering. Use Value: Absorbs 1.5 kJ surge energy (per IEEE C62.41 Cat. C) without degradation, maintaining VWM stability after repeated 6 kV ring-wave transients. |
Use Scenario: Protecting IGBT gate drivers and DC-link capacitors in solar string inverters exposed to grid-switching transients and ground potential rise. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC-link (e.g., 1000 V bus), triggered only during overvoltage excursions exceeding 85.5 V. Use Value: Prevents destructive overvoltage on gate oxide layers by clamping transients to 137 V - well below 200 V typical IGBT gate rating. |
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 | DO-214AA package (SMB), 100 W lower PPPM (1400 W), identical VBR/VC specs, surface-mount only. | Requires SMT reflow process; unsuitable for through-hole legacy designs or high-vibration environments needing axial lead mechanical retention. | Select SMBJ100CA only when board space is constrained and automated assembly is used; verify thermal relief pad design for 1400 W pulse dissipation. |
| 1.5SMC100CA | DO-214AB (SMC) package, same 1500 W rating, but higher VBR tolerance (±6%), slightly higher VC (140 V), RoHS-compliant lead finish. | Offers tighter footprint than 1.5KE but lower creepage distance; not AEC-Q101 qualified in standard grade. | Choose 1.5SMC100CA for space-constrained industrial controls where UL 94 V-0 and 1500 W are mandatory, but automotive qualification is not required. |
Compared with 1.5KE100CA/54, SMBJ100CA trades mechanical robustness and through-hole compatibility for smaller footprint, while 1.5SMC100CA retains full 1500 W capability in a more compact SMC outline - neither offers the axial-leaded serviceability or AEC-Q101 HE3 variant availability of the 1.5KE family.

FAQ
What is the clamping voltage of the 1.5KE100CA/54 under maximum rated surge conditions?
The 1.5KE100CA/54 has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by protected circuitry during a full-rated surge event. The 1.5KE100CA/54 maintains this clamping performance bidirectionally and across its full operating temperature range.
Is the 1.5KE100CA/54 suitable for automotive applications?
Yes - the 1.5KE100CA/54 is offered in AEC-Q101 qualified variants (e.g., 1.5KE100CAHE3_B), which undergo rigorous stress testing for temperature cycling, humidity, and mechanical shock. While the base 1.5KE100CA/54 is commercial-grade, its 175 °C max junction temperature, glass-passivated junction, and UL 94 V-0 molding make it suitable for non-safety-critical automotive subsystems like infotainment power supplies and lighting control modules.
How does the 1.5KE100CA/54 differ from unidirectional 1.5KE100A variants?
The 1.5KE100CA/54 is bidirectional with symmetrical breakdown in both polarities and no cathode marking, whereas the 1.5KE100A is unidirectional with a cathode band and forward conduction capability. The 1.5KE100CA/54 clamps positive and negative transients equally, making it ideal for AC-coupled lines or floating DC buses; the 1.5KE100A is used where polarity is fixed and forward voltage drop matters, such as in DC power input protection.
What is the thermal resistance of the 1.5KE100CA/54, and how does it affect layout?
The 1.5KE100CA/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To manage 1500 W pulse energy, PCB layout must maximize copper area connected to both leads - especially using ≥0.5 oz copper pours extending ≥10 mm beyond each pad - and maintain 0.375" (9.5 mm) lead length as specified in the DO-201AD outline to ensure rated RθJL.
Can the 1.5KE100CA/54 be used in parallel to increase surge handling capacity?
No - the 1.5KE100CA/54 should not be paralleled without external balancing resistors due to VBR tolerance (±5%) causing current imbalance. Uneven sharing may cause one device to absorb >80% of the surge, leading to premature failure. For higher power, use a single higher-rated device (e.g., 3.0KE100CA) or implement staged protection with upstream MOVs and downstream TVS arrays.
