Product details
Overview
1V5KE100CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 95–105 V at 1 mA test current, reverse stand-off voltage 85.5 V, clamping voltage 137 V at 11.0 A peak pulse current, and junction temperature range −55°C to +175°C. It protects power rails and signal lines in industrial power supplies and motor drives against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE100CA datasheet, 1V5KE100CA pinout, 1V5KE100CA application, or 1V5KE100CA equivalent, key selection criteria include bidirectional clamping performance, 137 V VC at 11.0 A IPPM, DO-201 mechanical compatibility, RoHS/halogen-free compliance, and 175°C maximum junction temperature for high-reliability thermal environments.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging an avalanche breakdown mechanism to divert surge energy away from downstream circuitry. Its bidirectional symmetry enables protection of AC-coupled or floating signal paths without polarity concerns.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of 10/1000 µs waveform transients up to 1500 W. Reverse leakage remains below 5 µA at 85.5 V, minimizing standby power loss in high-impedance circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W at 1 ms - sustains single high-energy surges common in industrial lightning and inductive switching events |
| Breakdown Voltage VBR | 95–105 V @ 1 mA - defines precise avalanche onset threshold for reliable clamping activation |
| Reverse Stand-off Voltage VRWM | 85.5 V - maximum continuous operating voltage before leakage exceeds 5 µA |
| Clamping Voltage VC | 137 V @ 11.0 A IPPM - limits voltage seen by protected ICs during worst-case 10/1000 µs surge |
| Junction Temperature Range | −55°C to +175°C - supports operation in under-hood automotive, industrial motor control, and outdoor power electronics |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical glass-passivated body with cathode band marking for unidirectional variants; for 1V5KE100CA (bidirectional), polarity is non-directional - both terminals function identically as symmetrical avalanche junctions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead serves as input/output - no polarity dependency; connects across protected line-to-line or line-to-ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable avalanche characteristics and long-term reliability under repeated surge stress |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping fidelity |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and environmental regulations for global industrial and consumer deployments |
| 175°C maximum junction temperature | Enables use in thermally demanding environments such as enclosed power converters and motor drive inverters |
Applications
| Industrial Power Supply Protection | Motor Drive Surge Suppression |
|---|---|
Use Scenario: Protecting DC bus inputs and auxiliary power rails in programmable logic controller (PLC) power modules against load dump and relay coil flyback. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across input terminals to limit transient overvoltage before it reaches DC-DC controllers and gate drivers. Use Value: Clamps 10/1000 µs surges to ≤137 V while handling 1500 W peak power, preventing latch-up or destruction of 100 V-rated MOSFETs and regulators. | Use Scenario: Safeguarding encoder interface lines and analog sensor inputs in variable-frequency drives exposed to EFT and inductive coupling from IGBT switching. IC Role / Device Role / Timing Role: Line-to-line TVS on differential RS-485 or analog feedback paths to absorb coupled transients without distorting signal integrity. Use Value: Symmetrical 95–105 V breakdown ensures equal clamping in both directions, preserving common-mode rejection and avoiding DC bias shift in precision analog circuits. |
| Lighting System Transient Protection | ESD-Sensitive Interface Protection |
Use Scenario: Guarding constant-current LED driver outputs against voltage spikes caused by hot-plug events or cable discharge in streetlight and stadium lighting systems. IC Role / Device Role / Timing Role: Output-side TVS connected between output and return to clamp open-circuit transients before they damage LED strings or current-sense amplifiers. Use Value: 137 V clamping voltage ensures LED string forward voltage (typically 90–110 V) remains within safe margin during surge, preventing catastrophic overcurrent failure. | Use Scenario: Protecting USB, CAN, or I²C lines in industrial HMIs and edge gateways from human-body-model (HBM) ESD and electrical fast transients. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed at connector entry point to shunt ESD energy before reaching PHY or microcontroller I/O pins. Use Value: Sub-µA leakage at 85.5 V prevents signal degradation on high-impedance buses, while 1 ns response captures ESD pulses before internal IC protection triggers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | 600 W peak power, SMB package (surface-mount), lower IPPM (6.5 A), same 100 V nominal breakdown | Designed for PCB space-constrained designs; not suitable for high-energy 1500 W surges | Select when board area is limited and surge threat level is lower (e.g., consumer-grade ESD only) |
| 1N6295A | Same die family, identical electrical specs, but unidirectional variant - requires correct polarity placement | Only usable where circuit topology enforces defined polarity (e.g., DC rail to ground) | Choose only if polarity is fixed and layout allows directional mounting; otherwise 1V5KE100CA offers design flexibility |
Compared with SMBJ100CA and 1N6295A, the 1V5KE100CA delivers higher surge robustness in through-hole form factor and eliminates polarity constraints-making it optimal for high-reliability industrial power interfaces where layout flexibility and 1500 W immunity are required.

FAQ
What is the clamping voltage of the 1V5KE100CA under standard 10/1000 µs surge conditions?
The 1V5KE100CA has a maximum clamping voltage (VC) of 137 V when subjected to a 11.0 A peak pulse current (IPPM) under the standardized 10/1000 µs double-exponential surge waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for downstream components rated up to 120 V.
Is the 1V5KE100CA unidirectional or bidirectional, and how does that affect its circuit placement?
The 1V5KE100CA is a bidirectional TVS diode, indicated by the "CA" suffix. Its symmetrical avalanche structure allows connection across any two points needing transient protection-such as line-to-line or line-to-ground-without regard to polarity. This simplifies layout versus unidirectional alternatives like 1N6295A, which require correct anode/cathode orientation.
What is the maximum continuous reverse operating voltage for the 1V5KE100CA?
The maximum continuous reverse operating voltage-the reverse stand-off voltage (VRWM)-for the 1V5KE100CA is 85.5 V. At this voltage, reverse leakage current remains below 5 µA, ensuring minimal power loss and no unintended conduction during normal operation in 72–80 V DC systems.
Does the 1V5KE100CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE100CA is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads comply with J-STD-002 solderability standards-making it suitable for environmentally regulated industrial and consumer applications.
What package type does the 1V5KE100CA use, and what are its mechanical highlights?
The 1V5KE100CA uses the DO-201 axial-leaded package. Key mechanical features include glass passivation for junction stability, UL 94V-0 rated epoxy molding compound, pure tin-plated leads qualified to J-STD-002, and compliance with JESD 201 Class 2 whisker testing-ensuring long-term solder joint integrity and reliability in vibration-prone environments.
