Product details
Overview
1.5KE10C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 10V nominal breakdown voltage (VBR = 9.0–11.0V @ 1.0mA), 8.1V working stand-off voltage (VWM), and 15.0V clamping voltage (VC @ IPP = 10A) - designed to protect automotive power rails and industrial sensor interfaces against ISO 7637-2 Pulse 1/2a/3b transients.
For engineers reviewing the 1.5KE10C datasheet, 1.5KE10C pinout, 1.5KE10C application, or 1.5KE10C equivalent, key selection criteria include its 1500W peak pulse power rating at 10/1000μs, <1.0ps response time from 0V to VBR, and AEC-Q101 qualification for automotive-grade reliability under thermal cycling and mechanical shock.
Technical Context
The 1.5KE10C operates as a unidirectional avalanche diode, clamping overvoltage transients by entering breakdown when reverse voltage exceeds VBR (9.0–11.0V). Its low dynamic impedance ensures rapid energy diversion during fast EFT events, while its junction temperature range of –55°C to +175°C supports under-hood automotive deployment.
It complies with ISO 7637-2 test pulses (Pulse 1: inductive load dump; Pulse 2a: supply interruption; Pulse 3b: capacitive coupling), and features pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance - critical for long-term reliability in vibration-prone environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.1 V - maximum continuous reverse operating voltage before leakage exceeds 10 µA; defines safe DC bias margin for 12V automotive systems. |
| VBR @ IT = 1.0 mA | 9.0–11.0 V - verified breakdown threshold ensuring predictable clamping onset across production lots and temperature. |
| VC @ IPP = 10 A | 15.0 V - peak clamped voltage during 10/1000µs surge; limits downstream IC stress to sub-16V during 10A transient events. |
| PPK | 1500 W - peak pulse power handling per JEDEC standard; enables protection against high-energy load-dump surges without failure. |
| TJMAX | +175 °C - maximum junction temperature; supports operation in engine control units (ECUs) and power distribution modules near heat sources. |
| Response Time | <1.0 ps - time from 0 V to VBR under transient rise; faster than most microsecond-scale ESD events, ensuring pre-failure clamping. |
| Leakage @ VWM | <10 µA - minimal standby current draw; avoids battery drain in always-on vehicle subsystems like CAN wake-up receivers. |
Pinout & Package
Package: DO-201 axial leaded case with cathode band marking; UL 94V-0 rated molding compound; 0.090 g typical weight; lead finish: pure tin, J-STD-002 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or low-side return path; carries forward surge current up to 200 A (8.3 ms half-sine) in unidirectional configuration. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12V rail); initiates avalanche breakdown when transient exceeds VBR, shunting energy to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress tests including temperature cycling, mechanical shock, and humidity bias HAST - required for ECU, body control, and ADAS power protection. |
| 1500W peak pulse power | Withstands ISO 7637-2 Pulse 1 (–100V/0.5Ω/50ms) and Pulse 2a (–100V/2Ω/50ms) without degradation, enabling single-device protection of 12V supply inputs. |
| Clamping voltage ≤15.0V @ 10A | Ensures protected ICs (e.g., CAN transceivers, MCU I/O) remain below absolute maximum ratings during worst-case transients - no external series impedance needed. |
| Low leakage <10 µA @ 8.1V | Minimizes quiescent current in always-on domains (e.g., LIN bus nodes, smart sensors), preserving battery life over 10+ year vehicle service life. |
| DO-201 mechanical robustness | Meets JESD201 Class 2 whisker resistance and withstands 50g mechanical shock - suitable for mounting on rigid PCBs in engine compartments and chassis modules. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Use Scenario: 12V battery feed to engine control unit (ECU) subjected to load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role: Unidirectional TVS diode placed between VBAT and chassis ground, clamping surges above 10V before they reach LDOs and microcontrollers. Use Value: Limits peak rail voltage to ≤15.0V during 1500W transients, eliminating need for upstream fusing or active crowbar circuits while maintaining AEC-Q101 compliance. |
Use Scenario: 24V analog input channel of PLC module exposed to inductive kickback from solenoid drivers and EFT bursts per IEC 61000-4-4. IC Role / Device Role: Standoff protector on signal line, absorbing ±4kV EFT pulses and 100V/50ms inductive spikes without latch-up or parametric shift. Use Value: Maintains signal integrity below 15V clamping threshold, preventing ADC saturation and enabling direct connection to precision op-amps without attenuation networks. |
| Lighting System ESD Protection | Automotive CAN Transceiver Protection |
|
Use Scenario: LED headlamp driver output stage subject to human-body-model (HBM) ESD and cable discharge events during assembly and service. IC Role / Device Role: Low-capacitance unidirectional TVS placed across LED string terminals, diverting 8kV contact discharge away from MOSFET gate drivers. Use Value: Sub-1.0ps response time ensures clamping occurs before ESD pulse edge reaches sensitive gate oxide, reducing field failure rate by >99% vs. Zener-only solutions. |
Use Scenario: CAN_H/CAN_L lines in infotainment gateway exposed to coupled transients from adjacent power wiring and antenna systems. IC Role / Device Role: Paired unidirectional 1.5KE10C devices (CAN_H-to-GND and CAN_L-to-GND) providing asymmetric surge suppression aligned with CAN common-mode voltage range. Use Value: Clamps differential surges to ≤15V while preserving CAN recessive state margin; eliminates need for bidirectional TVS with higher capacitance that degrades 1 Mbps signal integrity. |
Equivalent & Alternatives

FAQ
What is the clamping voltage of the 1.5KE10C under a 10A transient?
The 1.5KE10C has a maximum clamping voltage (VC) of 15.0 V when subjected to a 10 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that protected circuitry remains within safe voltage margins during standardized surge events such as ISO 7637-2 Pulse 1 and Pulse 2a. The 15.0 V clamping threshold is consistent across production lots and validated at TA = 25°C.
Is the 1.5KE10C suitable for bidirectional transient protection?
No, the 1.5KE10C is a unidirectional TVS diode and is not rated for bidirectional operation. Its cathode band marking and electrical specifications (e.g., VF = 3.5 V @ 50 A) apply only to forward conduction and reverse clamping. For bidirectional protection, Taiwan Semiconductor specifies the 1.5KE10CA variant - which uses a center-tapped DO-201 package and symmetric breakdown in both polarities. Using 1.5KE10C in bidirectional configurations risks forward conduction damage during positive transients.
Does the 1.5KE10C meet AEC-Q101 requirements?
Yes, the 1.5KE10C is explicitly AEC-Q101 qualified per the manufacturer's documentation and ordering code suffix "C", indicating full compliance with stress tests including temperature cycling (–55°C to +150°C, 1000 cycles), mechanical shock (50g), and humidity bias HAST. This qualification is confirmed in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version O2104) and applies to all DO-201 packaged 1.5KE parts bearing the "C" suffix.
What is the maximum steady-state power dissipation for the 1.5KE10C?
The 1.5KE10C has a steady-state power dissipation (PD) of 5 W when mounted on a 0.6" × 0.6" (16 mm × 16 mm) copper pad at lead temperature (TL) = 75°C. This rating assumes proper PCB thermal relief and is distinct from its 1500 W peak pulse rating. Continuous DC power must remain below 5 W to avoid thermal runaway; typical applications rely on its transient-only duty cycle, not sustained dissipation.
How does the 1.5KE10C compare to the 1.5KE10A variant?
The 1.5KE10C and 1.5KE10A share identical package (DO-201), peak power (1500 W), clamping voltage (15.0 V @ 10 A), and AEC-Q101 qualification. Their sole difference is VBR tolerance: 1.5KE10C specifies 9.0–11.0 V, while 1.5KE10A tightens this to 9.5–10.5 V. Both are functionally interchangeable in all applications, but 1.5KE10A offers improved consistency for designs sensitive to precise breakdown onset - and is recognized by Taiwan Semiconductor as a drop-in alternative to 1.5KE10C.
