Product details
Overview
1.5KE10CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 10 V breakdown voltage (VBR min/max = 9.5–10.5 V), 8.55 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 103 A, and operates from –55 °C to +175 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the 1.5KE10CA-E3/54 datasheet, 1.5KE10CA-E3/54 pinout, 1.5KE10CA-E3/54 application, or 1.5KE10CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM ≈ 1.7), JEDEC 1.5KE package compatibility, and AEC-Q101 qualification eligibility (via HE3 suffix variants).
Technical Context
This device functions as a silicon avalanche diode operating in reverse breakdown to shunt transient energy away from sensitive circuitry. Its bidirectional configuration enables symmetrical clamping on AC-coupled or differential lines without polarity constraints, with no cathode marking required.
It delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, exhibits <1 ns response time, and maintains stable clamping performance across –55 °C to +175 °C junction temperature range - validated per ANSI/IEEE C62.35 and UL 497B standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.5 V / 10.5 V - ensures reliable conduction onset within ±5% of nominal 10 V rating under 1 mA test current |
| VWM | 8.55 V - maximum continuous working voltage before leakage exceeds 10 µA, defining safe operating margin |
| VC @ IPPM | 14.5 V - clamps transient peaks to ≤14.5 V at 103 A peak pulse current, limiting downstream stress |
| PPPM | 1500 W - handles high-energy surges (e.g., ISO 7637-2 Pulse 1/2/5a) without failure |
| IPPM | 103 A - peak surge current capacity under 10/1000 µs waveform, enabling robust ESD/lightning protection |
| TJ range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Package | JEDEC DO-201AD (1.5KE) - industry-standard axial leaded package with 0.375" lead length, UL 94 V-0 rated epoxy |
Pinout & Package
1.5KE10CA-E3/54 uses a two-terminal axial-leaded DO-201AD (Case Style 1.5KE) package. As a bidirectional TVS, it has no polarity marking - both leads are electrically symmetric and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (both) | Transient current path | Identical terminals conduct equally in either direction during overvoltage events; no PCB orientation requirement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 (4 kV) and ISO 7637-2 Pulse 5a requirements for automotive electronics |
| Clamping voltage ratio (VC/VWM) ≈ 1.7 | Minimizes voltage overshoot during fast transients, protecting 3.3 V/5 V logic interfaces |
| Response time < 1 ns | Activates before most IC damage thresholds are exceeded, outperforming MOVs and GDTs |
| RoHS-compliant matte tin plating | Supports lead-free reflow and wave soldering per J-STD-002/JESD 22-B102 |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential signal pair or supply rail to divert surge current before reaching precision amplifier or microcontroller input.

IC Role / Device Role / Timing Role: Primary-level protector mounted at connector entry point to absorb bulk surge energy before secondary TVS or integrated ESD structures. Use Value: Provides 1500 W pulse handling with sub-nanosecond response - critical for preserving data integrity during multi-kV transients. | Use Scenario: Suppressing commutation spikes from brushed DC motors or relay coils in white goods (e.g., washing machine control boards). IC Role / Device Role / Timing Role: Across-motor terminals or coil flyback path to clamp inductive kickback and prevent MCU reset or MOSFET gate oxide damage. Use Value: Withstands 200 A non-repetitive forward surge (IFSM), ensuring survival during frequent motor start-stop cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Lower peak power (600 W), smaller SMB package (surface-mount), same 10 V VWM/14.5 V VC | Better suited for space-constrained PCBs; less robust for high-energy automotive load dump | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5KE10A-E3/54 | Unidirectional variant; includes cathode band marking; identical VBR, VWM, VC, and PPPM | Required only for DC-biased lines where polarity is fixed and reverse conduction must be blocked | Choose only if circuit topology mandates unidirectional clamping - otherwise 1.5KE10CA-E3/54 offers greater design flexibility |
Compared with SMBJ10CA, 1.5KE10CA-E3/54 provides 2.5× higher surge power handling in an axial through-hole package ideal for high-reliability industrial connections; versus 1.5KE10A-E3/54, it eliminates polarity constraints for AC-coupled or floating signal paths without sacrificing electrical performance.

FAQ
What is the clamping voltage of the 1.5KE10CA-E3/54 under maximum rated surge current?
The 1.5KE10CA-E3/54 clamps to a maximum of 14.5 V at its peak pulse current (IPPM) of 103 A, measured using the standard 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet (Document Number: 88301, Rev. 09-Aug-2022) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5KE10CA-E3/54 achieves this with minimal voltage overshoot relative to its 8.55 V working voltage.
Is the 1.5KE10CA-E3/54 RoHS compliant and lead-free solder compatible?
Yes, the 1.5KE10CA-E3/54 carries the "E3" suffix indicating full RoHS compliance and matte tin-plated leads qualified for lead-free soldering per J-STD-002 and JESD 22-B102. It withstands solder dip at 275 °C for up to 10 seconds and passes JESD 201 Class 1A whisker testing. The 1.5KE10CA-E3/54 is suitable for modern reflow and wave solder processes without derating.
How does the bidirectional nature of the 1.5KE10CA-E3/54 affect its placement in circuit design?
The 1.5KE10CA-E3/54 has no polarity marking and conducts identically in both directions, making it ideal for AC-coupled, differential, or floating signal lines - such as RS-485 buses or transformer-isolated interfaces - where voltage transients may swing positive or negative. Unlike unidirectional variants like 1.5KE10A-E3/54, the 1.5KE10CA-E3/54 eliminates orientation concerns during assembly and avoids risk of incorrect installation. Its symmetry simplifies layout and enhances system-level surge resilience.
What is the maximum operating temperature range for the 1.5KE10CA-E3/54?
The 1.5KE10CA-E3/54 is rated for junction and storage temperatures from –55 °C to +175 °C, supporting deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. This wide range is enabled by its glass-passivated silicon junction and thermally robust DO-201AD package. Derating applies above 25 °C ambient per Figure 2 in the Vishay datasheet, but the 1.5KE10CA-E3/54 maintains full 1500 W pulse capability at TJ ≤ 125 °C.
Can the 1.5KE10CA-E3/54 be used as a direct replacement for the unidirectional 1.5KE10A-E3/54?
No - the 1.5KE10CA-E3/54 is not a drop-in replacement for 1.5KE10A-E3/54 in circuits requiring unidirectional blocking, such as DC power rails where reverse leakage must be minimized. While both share identical VBR, VWM, and VC specs, the 1.5KE10CA-E3/54 conducts in both directions and lacks cathode identification. Substitution is only valid in truly bidirectional or AC-coupled applications; using 1.5KE10CA-E3/54 on a DC supply line risks unintended conduction during normal operation.
