Product details
Overview
1.5KE13CA/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 13 V nominal breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 1500 W peak pulse power (10/1000 µs), and clamps to ≤18.2 V at 82.4 A peak pulse current - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the 1.5KE13CA/54 datasheet, 1.5KE13CA/54 pinout, 1.5KE13CA/54 application, or 1.5KE13CA/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, JEDEC 1.5KE package details, thermal derating curves, and direct alternatives with documented parameter differences.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its 10/1000 µs waveform response enables sub-nanosecond transient suppression, and it maintains stable VBR with ±0.081 %/°C temperature coefficient.
The 1.5KE13CA/54 exhibits low incremental surge resistance and fast recovery, supporting repetitive surge events at ≤0.01 % duty cycle. It is rated for TJ = –55 °C to +175 °C and meets UL 94 V-0 flammability requirements in its molded epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise clamping onset threshold under standardized test conditions |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| VC @ IPPM | ≤18.2 V at 82.4 A - actual clamped voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity without failure |
| IPPM | 82.4 A - maximum non-repetitive surge current the device safely clamps |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| Package | JEDEC 1.5KE - axial-leaded, DO-201AD outline with 0.375" lead length, compatible with through-hole PCB assembly |
Pinout & Package
1.5KE13CA/54 uses a two-terminal axial-leaded package (Case Style 1.5KE, DO-201AD). No polarity marking is present - terminals are electrically symmetric for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead may connect to line or ground; no cathode band - enables flexible placement in AC-coupled or differential paths |
| Leads (matte tin plated) | Interconnect interface | Solderable per J-STD-002/JESD 22-B102; withstands 275 °C dip for 10 s |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable long-term VBR and low leakage (<5 µA at VWM) across temperature and life cycles |
| 1500 W peak pulse rating | Handles lightning-induced surges (IEC 61000-4-5 Level 4) on 24 V industrial buses or CAN lines |
| Sub-nanosecond response time | Clamps transients before sensitive ICs (e.g., microcontrollers, RS-485 transceivers) experience overvoltage damage |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures - required for industrial control panel certifications |
| AEC-Q101 qualified variants available | HE3 suffix versions meet automotive-grade reliability for engine control and body electronics |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine control units from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across sensor signal and ground, absorbing ±100 V transients within nanoseconds. Use Value: Limits voltage seen by ADC input to ≤18.2 V, preventing latch-up or permanent damage to 3.3 V/5 V signal conditioning circuitry. |
Use Scenario: Shielding 24 V digital input modules in programmable logic controllers from field-wiring induced surges. IC Role / Device Role / Timing Role: Line-to-ground TVS on each discrete input channel, operating in parallel with optocoupler input stages. Use Value: Maintains functional integrity during 1 kV/500 A surge events (IEC 61000-4-5), avoiding false triggering or input stage failure. |
| Telecom Line Interface | Consumer Power Adapter ESD |
Use Scenario: Safeguarding Ethernet PHY or DSL line drivers against induced lightning surges on outdoor copper pairs. IC Role / Device Role / Timing Role: Primary protection device on line side of isolation transformer, shunting common-mode transients to chassis ground. Use Value: Clamps 6 kV contact ESD (IEC 61000-4-2) and 10/700 µs telecom surges to safe levels before reaching magnetics or PHY IC. |
Use Scenario: Secondary-side overvoltage protection in AC-DC adapters for USB-C PD and smart home devices. IC Role / Device Role / Timing Role: Bidirectional clamp across DC output rails (e.g., 5 V, 9 V, 12 V) to suppress switching noise and external coupling. Use Value: Prevents overvoltage shutdown of connected devices during transient load steps or adapter regulation faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13CA | Same VBR range (12.4–13.7 V), but lower PPPM = 400 W and SMC (DO-214AB) surface-mount package | Requires PCB redesign for SMT layout; suitable only where space constraints preclude axial leads | Select when board area is critical and surge energy is limited to <400 W |
| ON Semiconductor 1.5SMC13CA | Identical electrical specs (VBR, VC, PPPM), same 1.5KE package, but RoHS-compliant matte tin plating per JESD 22-B102 | No functional change; drop-in replacement for legacy designs requiring alternate sourcing | Choose for dual-sourcing assurance without layout or qualification impact |
Compared with 1.5KE13CA/54, SMAJ13CA trades surge robustness for compactness, while 1.5SMC13CA offers identical performance in the same through-hole form factor - making it the lowest-risk alternative for continuity-driven production.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13CA/54?
The 1.5KE13CA/54 has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing ±5.4 % tolerance around the nominal 13 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 12 V system interfaces without premature conduction.
Does the 1.5KE13CA/54 require a heatsink for standard operation?
No, the 1.5KE13CA/54 does not require an external heatsink for transient suppression duty cycles (≤0.01 %). Its RθJA = 75 °C/W and RθJL = 15.4 °C/W allow adequate thermal dissipation through leads alone during short-duration surges. Continuous power dissipation is limited to 6.5 W at TL = 75 °C, but typical TVS use involves infrequent pulses - not steady-state loading.
How does the 1.5KE13CA/54 differ from unidirectional 1.5KE13A?
The 1.5KE13CA/54 is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas the 1.5KE13A is unidirectional with a cathode band and conducts only in reverse bias. The 1.5KE13CA/54 supports AC-coupled or floating signal lines (e.g., RS-485, CAN), while 1.5KE13A suits DC-biased rails like 12 V power inputs where polarity is fixed.
Is the 1.5KE13CA/54 compliant with AEC-Q101 for automotive use?
The base 1.5KE13CA/54 is commercial-grade; however, the AEC-Q101 qualified version is designated 1.5KE13CAHE3_B (or similar HE3 suffix). That variant undergoes extended stress testing per AEC-Q101 Rev D and is approved for automotive powertrain and chassis applications - the /54 tape-and-reel packaging code itself does not indicate qualification.
What is the maximum clamping voltage of the 1.5KE13CA/54 at its rated surge current?
The 1.5KE13CA/54 clamps to a maximum of 18.2 V at its rated peak pulse current of 82.4 A (10/1000 µs waveform). This value is measured under standardized test conditions and represents the worst-case voltage imposed on protected circuitry during a full 1500 W transient event - a key parameter for verifying compatibility with downstream 3.3 V or 5 V IC absolute maximum ratings.
