Product details
Overview
1.5KE13CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 13V, clamping voltage 19.0V at 82A peak pulse current, and working stand-off voltage 10.5V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE13CA datasheet, 1.5KE13CA pinout, 1.5KE13CA application, or 1.5KE13CA equivalent, this part delivers fast sub-nanosecond response for bidirectional ESD and surge protection in DC power inputs, CAN bus interfaces, and sensor signal lines where low leakage (<1µA above 10V) and AEC-Q101 qualification are required.
Technical Context
The 1.5KE13CA operates as a bidirectional avalanche diode, triggering symmetrically in both polarities when transient voltage exceeds its 11.7–14.3V breakdown range at 1mA test current. Its 19.0V clamping voltage at 82A (10/1000μs waveform) limits energy dissipation to safe levels for downstream ICs.
Designed for high-reliability automotive environments, it meets AEC-Q101 stress requirements and ISO 7637-2 immunity standards. The DO-201 package supports lead-free soldering per J-STD-002 and passes JESD 201 Class 2 whisker testing, with junction temperature rated from –55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7V / 14.3V at 1mA - defines precise voltage threshold for bidirectional avalanche conduction |
| VWM | 10.5V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1µA |
| VC @ IPP | 19.0V at 82A (10/1000μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPK | 1500W - peak pulse power handling capability under standardized 10/1000μs transient waveform |
| IR @ VWM | <1µA - ultra-low reverse leakage ensures minimal standby power loss in battery-powered systems |
| TJ max | +175°C - enables operation in under-hood automotive or high-temperature industrial enclosures |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and pure tin plating |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional variants; 1.5KE13CA is bidirectional and non-polarized - both leads serve as symmetrical terminals with no designated anode/cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 | Bidirectional terminal | Connects to either side of protected line - identical electrical behavior in both directions |
| Lead 2 | Bidirectional terminal | Completes symmetrical TVS path - no polarity dependency; used in differential or floating rail protection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per JEDEC standards |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (ESD coupling) waveforms |
| Fast response time | <5.0ns turn-on from 0V to VBR - critical for suppressing nanosecond-scale EFT bursts before IC damage occurs |
| Low dynamic impedance | Ensures stable clamping performance across varying surge amplitudes without voltage runaway |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive - suitable for environmentally regulated industrial and automotive production |
Applications
| Automotive Power Input Protection | CAN Bus Transient Suppression |
|---|---|
|
Use Scenario: 12V battery feed to body control module exposed to load dump and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input rails to clamp transients before DC-DC converter input stage. Use Value: Clamps 10/1000μs surges to ≤19.0V while dissipating 1500W - prevents overvoltage failure of upstream regulators and microcontrollers. |
Use Scenario: CAN_H/CAN_L lines in vehicle infotainment gateway subjected to ESD and coupled noise. IC Role / Device Role / Timing Role: Differential TVS pair (one per line to ground) suppressing common-mode transients without distorting data signals. Use Value: Sub-5ns response captures fast EFT events; low capacitance avoids signal integrity degradation on 1Mbps CAN bus. |
| Industrial Sensor Signal Line Protection | LED Driver Input Stage Protection |
|
Use Scenario: 4–20mA current loop sensor interface in factory automation PLC I/O module. IC Role / Device Role / Timing Role: Bidirectional TVS across signal and return lines to absorb induced lightning surges and relay switching spikes. Use Value: 10.5V VWM allows full 20mA loop compliance while clamping >13V transients - preserves analog accuracy and prevents op-amp latch-up. |
Use Scenario: AC/DC LED driver primary-side input subjected to mains-borne surges and capacitor discharge transients. IC Role / Device Role / Timing Role: Across-line TVS on rectified DC bus to limit voltage overshoot during MOV failure or inrush events. Use Value: 1500W rating handles repetitive 10/1000μs surges up to 82A; 175°C TJ rating sustains reliability in thermally constrained LED housing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13CA | Same DO-214AC (SMA) package; lower PPK = 400W; VC = 21.5V @ 19.4A | Lower surge capacity suits consumer electronics; not AEC-Q101 qualified | Select for cost-sensitive non-automotive designs where 400W peak power suffices |
| ON Semiconductor 1.5SMC13CA | DO-214AB (SMC) package; PPK = 1500W; VC = 21.2V @ 70.7A; higher thermal resistance | Surface-mount alternative requiring PCB rework; less robust thermal performance than DO-201 axial leads | Choose only if SMT assembly is mandatory and board layout accommodates larger SMC footprint |
Compared with SMAJ13CA and 1.5SMC13CA, the 1.5KE13CA offers superior surge robustness in through-hole form factor, AEC-Q101 validation for automotive use, and lower clamping voltage (19.0V vs. ≥21.2V), enabling tighter protection margins for sensitive 12V logic rails.

FAQ
What does the 'CA' suffix indicate in 1.5KE13CA?
The 'CA' suffix in 1.5KE13CA denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, unlike unidirectional 'C' variants. This makes 1.5KE13CA ideal for protecting AC-coupled lines, differential buses like CAN, or floating DC rails where polarity reversal may occur. All electrical characteristics apply identically in either direction.
Is 1.5KE13CA AEC-Q101 qualified?
Yes, 1.5KE13CA is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes rigorous stress testing including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock to validate reliability for automotive under-hood and chassis applications. The 'H' ordering code (e.g., 1.5KE13CAH) denotes AEC-Q101-compliant production lots.
What is the maximum clamping voltage of 1.5KE13CA during a surge event?
The maximum clamping voltage (VC) of 1.5KE13CA is 19.0V at 82A peak pulse current under the standard 10/1000μs waveform. This value is guaranteed across the operating temperature range and represents the highest voltage imposed on the protected circuit during worst-case transient conditions - critical for ensuring downstream 12V-rated ICs remain within absolute maximum ratings.
Can 1.5KE13CA be used in place of a unidirectional TVS like 1.5KE13C?
No - 1.5KE13CA and 1.5KE13C are electrically distinct: 1.5KE13CA is bidirectional with symmetrical VBR, while 1.5KE13C is unidirectional and requires correct anode/cathode orientation. Substituting one for the other risks improper clamping or open-circuit behavior. Use 1.5KE13CA only where bidirectional protection is specified; verify polarity markings and schematic symbol before replacement.
What is the leakage current specification for 1.5KE13CA at its working voltage?
At its working stand-off voltage (VWM) of 10.5V, the maximum blocking leakage current (ID) for 1.5KE13CA is <1µA at 25°C. This ultra-low leakage ensures minimal power loss in always-on systems such as automotive body controllers or IoT sensor nodes, supporting long battery life and stable reference voltages in precision analog circuits.
