Product details
Overview
1.5KE100C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 100V, working stand-off voltage 81.0V, clamping voltage 144V at 10.9A peak pulse current, and junction temperature range −55°C to +175°C. It protects automotive power electronics and industrial control inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE100C datasheet, 1.5KE100C pinout, 1.5KE100C application, or 1.5KE100C equivalent, key selection criteria include unidirectional polarity, 100V VBR (min 90V, max 110V), 144V VC clamping at 10.9A, DO-201 mechanical compatibility, and AEC-Q101 qualification status (not applicable to standard 1.5KE100C).
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (90–110V at 1mA), it avalanches to limit downstream voltage to ≤144V. Its low dynamic impedance ensures rapid energy diversion during 10/1000μs surges.
Designed for primary-side surge protection in DC power rails, it sustains 1500W non-repetitive peak power per JEDEC test conditions, with <1.0ps response time from 0V to VBR, and leakage current <1μA above 10V - critical for low-power standby circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=1mA | 90–110V: defines minimum and maximum avalanche initiation voltage under standardized test current |
| VWM | 81.0V: maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP=10.9A | 144V: clamped voltage during 10/1000μs surge - determines protected circuit's maximum stress level |
| PPK | 1500W: peak pulse power handling capability - sets maximum transient energy absorption capacity |
| IPP | 10.9A: peak impulse current at which VC is specified - used to size series impedance and verify margin |
| Junction Temp Range | −55°C to +175°C: enables deployment in under-hood automotive and high-temp industrial environments |
| Leakage @ VWM | <1μA: ensures minimal standby power loss in battery-powered or always-on systems |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to system ground or low-side return path; defines direction of transient conduction |
| Cathode | Protected line input terminal | Connected to line being protected (e.g., 12V rail); avalanche occurs when cathode-to-anode voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 144V max clamping at 10.9A ensures downstream ICs rated for ≤150V survive ISO 7637-2 transients |
| Response speed | <1.0ps turn-on time enables suppression before sensitive logic or analog stages are over-stressed |
| Surge rating | 1500W peak power at 10/1000μs waveform meets automotive load-dump and inductive-switching immunity requirements |
| Thermal robustness | 175°C max junction temperature supports operation in engine-control units and motor-drive enclosures |
| Leakage control | <1μA at 81V allows use in high-impedance sensor bias networks without signal drift |
Applications
| Automotive Power Input Protection | Industrial PLC Digital Input Protection |
|---|---|
|
Use Scenario: 12V battery-fed ECU power rail exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between rail and chassis ground to clamp transients above 81V. Use Value: Limits rail voltage to ≤144V during 10/1000μs pulses, protecting 16V-rated LDOs and microcontrollers without derating. |
Use Scenario: 24V digital input channel on programmable logic controller receiving signals from field sensors. IC Role / Device Role / Timing Role: Primary-level transient suppressor on input line prior to optocoupler or Schmitt trigger interface. Use Value: Absorbs EFT bursts (IEC 61000-4-4) and inductive kickback, preventing false triggering and latch-up in input conditioning circuitry. |
| LED Driver Overvoltage Clamp | DC Motor Controller Flyback Suppression |
|
Use Scenario: Constant-current LED driver board powered from 48V supply in transportation lighting. IC Role / Device Role / Timing Role: Reverse-biased TVS across output terminals to clamp inductive flyback and hot-swap surges. Use Value: Clamps transients to 144V, staying below 150V absolute maximum rating of LED driver ICs and MOSFETs. |
Use Scenario: H-bridge motor driver PCB where back-EMF from brushed DC motor causes voltage spikes on supply rail. IC Role / Device Role / Timing Role: Rail-to-ground TVS on main 24V/48V bus to absorb bidirectional energy from commutation events. Use Value: Diverts >10A surge currents within nanoseconds, preventing rail collapse and gate-driver damage during motor stall or reversal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package, 100V VBR, 144V VC @ 10.3A, 600W rating | Lower peak power (600W vs. 1500W); suitable for lower-energy transients or space-constrained layouts | Select SMBJ100A when board area is limited and surge energy is ≤600W; verify thermal pad layout for SMB footprint. |
| 1N6295 (JEDEC equivalent) | Identical electrical specs and DO-201 package; same VBR, VC, PPK, and pinout | No functional difference; direct second-source option with identical mechanical and electrical behavior | Choose 1N6295 for dual-sourcing assurance while maintaining identical BOM and layout - no redesign required. |
Compared with 1.5KE100C, SMBJ100A offers smaller footprint but reduced surge capacity, while 1N6295 provides full form-fit-function equivalence as a JEDEC-standardized second source.

FAQ
What is the polarity configuration of the 1.5KE100C?
The 1.5KE100C is a unidirectional TVS diode with cathode band marking indicating the protected line terminal. It conducts only when cathode voltage exceeds anode voltage by ≥90V, making it suitable for DC rail clamping where polarity is fixed. This differs from bidirectional variants like 1.5KE100CA, which protect AC or reversible signals.
Does the 1.5KE100C meet AEC-Q101 qualification?
No - the standard 1.5KE100C is not AEC-Q101 qualified. AEC-Q101 compliance is available only in variants marked with "H" suffix (e.g., 1.5KE100CH). The base 1.5KE100C meets ISO 7637-2 Pulse 1/2a/2b/3a/3b but lacks the extended reliability testing required for automotive-grade qualification.
What is the maximum clamping voltage of the 1.5KE100C under surge conditions?
The 1.5KE100C has a maximum clamping voltage (VC) of 144V at 10.9A peak pulse current with a 10/1000μs waveform. This value is guaranteed across temperature and lifetime, and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the 1.5KE100C compare to the 1.5KE100A variant?
The 1.5KE100A has tighter breakdown voltage tolerance (95–105V vs. 90–110V for 1.5KE100C), resulting in more consistent clamping onset. Both share identical VWM (81.0V), VC (144V), and PPK (1500W), but 1.5KE100A is preferred where precise voltage threshold control is required in precision power monitoring circuits.
Can the 1.5KE100C be used in bidirectional signal lines?
No - the 1.5KE100C is strictly unidirectional and will not suppress positive transients on grounded lines or negative transients on VCC-referenced nodes. For bidirectional protection, use the 1.5KE100CA variant, which features symmetrical breakdown in both directions and identical 100V nominal rating.
