Product details
Overview
1.5KE220C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 220 V, clamping voltage 344 V at 4.5 A peak pulse current, and working stand-off voltage 175 V. It protects automotive power electronics and industrial control inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220C datasheet, 1.5KE220C pinout, 1.5KE220C application, or 1.5KE220C equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, real-world clamping performance under 10/1000 µs surge, and AEC-Q101-compliant alternatives for automotive-grade ESD and load-dump protection design.
Technical Context
The 1.5KE220C operates as a unidirectional avalanche diode, triggering at VBR = 198–242 V (tested at 1.0 mA), clamping to ≤344 V at IPP = 4.5 A under 10/1000 µs waveform. Its low dynamic impedance ensures rapid energy diversion during fast transients.
With junction temperature range –55°C to +175°C and <1 µA leakage above 10 V, it supports high-reliability operation in engine control units and industrial motor drives. Polarity is marked by cathode band; no internal series resistance or integrated thermal shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V - Ensures reliable turn-on across temperature and unit variation before clamping begins |
| VWM | 175 V - Maximum continuous reverse voltage without significant leakage; sets system operating margin |
| VC @ IPP | 344 V at 4.5 A - Peak clamped voltage seen by protected IC during 10/1000 µs surge; defines downstream voltage stress |
| PPK | 1500 W - Single-pulse surge power handling capability per JEDEC standard; validates robustness vs. load dump |
| IR @ VWM | <1 µA - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits |
| TJ max | +175 °C - Enables placement near hot components (e.g., power MOSFETs, ignition coils) without derating |
| 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 epoxy body with cathode band marking polarity. Leads are pure tin-plated, solderable per J-STD-002; weight ≈0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground-reference terminal | Connected to system ground or low-side return path; forms current sink during transient clamp |
| Cathode | Protected line input | Connected to line being protected (e.g., battery rail, sensor supply); cathode band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, mechanical shock, and humidity testing |
| 10/1000 µs surge rating | 1500 W peak power handling meets ISO 7637-2 Pulse 5a (load dump) requirements up to 12 V systems |
| Clamping response time | <1.0 ps from 0 V to VBR - Faster than most microcontroller I/O response, enabling pre-failure circuit protection |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for consumer, industrial, and automotive end-equipment with strict material restrictions |
| Low dynamic impedance | Minimizes VC rise under high di/dt events-critical for protecting 3.3 V or 5 V logic rails downstream of DC/DC converters |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery line in engine control module exposed to ISO 7637-2 Pulse 5a (load dump) up to 60 V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC/DC input to clamp overvoltage before regulator stage. Use Value: Limits transient voltage to ≤344 V, preventing damage to 40 V-rated buck controller and preserving system uptime. |
Use Scenario: 24 V analog input channel on PLC I/O module subjected to EFT bursts per IEC 61000-4-4. IC Role / Device Role / Timing Role: Front-end protection device shunting fast transients away from precision ADC front-end and op-amp buffer. Use Value: Sub-nanosecond response ensures clamping occurs before EFT edge propagates into signal chain, maintaining measurement accuracy. |
| Lighting System Surge Suppression | Motor Drive Control Signal Protection |
Use Scenario: LED driver input in commercial lighting fixture experiencing switching surges from nearby contactors. IC Role / Device Role / Timing Role: Standoff protection on primary-side bulk capacitor input to absorb repetitive 1500 W spikes. Use Value: 175 °C max junction temperature allows direct mounting on metal-core PCB near heat-generating MOSFETs without thermal derating. |
Use Scenario: Enable/disable signal line to gate driver IC in BLDC inverter subject to inductive kickback from gate loop. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) unidirectional clamp on logic-level control line to prevent false triggering. Use Value: 1 µA leakage at 175 V ensures no DC loading on open-drain microcontroller output driving optocoupler input. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ220A | Same DO-214AC (SMA) package; lower PPK = 400 W; VC = 356 V @ 3.5 A | Not AEC-Q101 qualified; rated for commercial/industrial only | Select when space-constrained layout requires surface-mount and 400 W surge capacity suffices |
| ON Semiconductor 1.5SMC220CA | Bidirectional variant in SMC package; same VBR range but dual-clamp symmetry; PPK = 1500 W | Supports AC-coupled or floating lines where polarity reversal may occur | Choose only if bidirectional protection is required; otherwise 1.5KE220C offers superior unidirectional leakage and lower cost |
Compared with SMAJ220A and 1.5SMC220CA, the 1.5KE220C provides AEC-Q101 qualification, axial DO-201 through-hole reliability for high-vibration environments, and tighter VBR tolerance (±10% vs ±5% for SMAJ), making it preferred for automotive power rail hardening where mechanical robustness and qualification traceability are mandatory.

FAQ
What is the maximum clamping voltage of the 1.5KE220C under standard test conditions?
The 1.5KE220C has a maximum clamping voltage (VC) of 344 V when subjected to a 10/1000 µs surge waveform at IPP = 4.5 A. This value is measured per JEDEC standards and defines the peak voltage imposed on protected circuitry during worst-case transient events. The 1.5KE220C maintains this clamping performance across its full operating temperature range.
Is the 1.5KE220C suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 1.5KE220C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor documentation. This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and mechanical shock-making the 1.5KE220C appropriate for under-hood automotive modules such as body control units and engine management systems.
How does the 1.5KE220C differ from the 1.5KE220CA variant?
The 1.5KE220C is unidirectional, while the 1.5KE220CA is bidirectional-meaning the latter clamps in both polarities and lacks anode/cathode distinction. The 1.5KE220C features a cathode band marking and is optimized for DC rail protection; the CA version suits AC-coupled or floating signal lines. Electrical parameters (VBR, VC, PPK) are identical between the two.
What is the working stand-off voltage (VWM) of the 1.5KE220C, and why does it matter?
The 1.5KE220C has a working stand-off voltage (VWM) of 175 V, which is the maximum continuous reverse voltage it can block without entering breakdown. This parameter ensures compatibility with 12 V or 24 V systems where normal operating voltage must remain well below VWM to avoid leakage or premature conduction-critical for stable power rail supervision in the 1.5KE220C's intended applications.
Can the 1.5KE220C be used in place of the 1.5KE220A?
The 1.5KE220C and 1.5KE220A share identical electrical specifications except for tighter VBR tolerance: the "C" version has VBR = 198–242 V (±10%), while the "A" version is 209–231 V (±5%). Both use DO-201 packaging and have identical thermal and surge ratings. The 1.5KE220C is fully interchangeable where ±10% tolerance is acceptable; the "A" variant is preferred only when tighter voltage matching is required.
