Product details
Overview
1.5KE220A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 220V nominal breakdown voltage (VBR = 209–231 V @ 1 mA), 185 V working stand-off voltage (VWM), and 328 V maximum clamping voltage (VC) at 4.8 A peak pulse current. It protects automotive power rails and industrial control inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220A R0G datasheet, 1.5KE220A R0G pinout, 1.5KE220A R0G application, or 1.5KE220A R0G equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25°C, unidirectional polarity marking, and AEC-Q101 qualification status of related variants.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (185 V), avalanches sharply at VBR (209–231 V), and limits transient energy by clamping to ≤328 V at 4.8 A IPP. Its <1.0 ps response time ensures protection before downstream ICs experience overvoltage stress.
Thermal design requires attention to steady-state dissipation (5 W at TL = 75°C on 16 mm × 16 mm copper pad) and non-repetitive pulse derating per Fig.2. Forward voltage is 3.5 V @ 50 A (per spec note for VBR ≤ 200 V; 1.5KE220A exceeds this, but VF not specified - omitted).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1 mA | 209–231 V: precise avalanche onset range defining minimum clamping threshold |
| VWM | 185 V: maximum continuous reverse voltage before leakage exceeds 1 µA |
| VC @ IPP = 4.8 A | 328 V: peak clamped voltage during 10/1000 µs surge - determines protected circuit's max stress |
| PPK | 1500 W: single-pulse surge power rating at TA = 25°C, derated above ambient |
| Junction Temp Range | −55°C to +175°C: supports under-hood automotive and industrial environments |
| Package | DO-201: axial-leaded, UL 94V-0 molded case with tin-plated leads per J-STD-002 |
| Polarity Marking | Cathode band: identifies cathode end for correct series placement in DC lines |
Pinout & Package
DO-201 package: axial leaded, cylindrical epoxy body with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and pass JESD 201 Class 2 whisker test. Weight ≈ 0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Connected to protected line (e.g., battery rail) | Current flows into anode during clamping; must be placed between source and load |
| Cathode | Connected to ground or lower potential reference | Marked with band; defines unidirectional conduction path and clamping polarity |
Key Features
| Feature | Design Value |
|---|---|
| 1500W surge capability | Withstands single 10/1000 µs transients up to 1500 W without degradation - suitable for ISO 7637-2 Pulse 5a |
| Low dynamic impedance | Enables tight clamping (VC − VBR ≈ 107 V) and fast energy diversion during fast-rising transients |
| Fast response time | <1.0 ps from 0 V to VBR ensures clamping initiates before most microsecond-scale transients fully develop |
| AEC-Q101 qualified option | R0G suffix indicates standard grade; A0G variant (1.5KE220A A0G) is AEC-Q101 qualified for automotive use |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS - meets environmental requirements for industrial and automotive PCBs |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECU power input subjected to load dump and alternator ripple per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VBAT and GND to clamp positive transients only. Use Value: Clamps 328 V at 4.8 A, limiting stress on upstream DC-DC converters and downstream MCU power pins. | Use Scenario: 24 V digital input channel on programmable logic controller exposed to inductive switching noise from solenoids and relays. IC Role / Device Role / Timing Role: Standoff protection device mounted at connector entry point to absorb repetitive 10/1000 µs surges. Use Value: 185 V VWM allows normal operation across full 24 V ±20% range while blocking leakage <1 µA. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
Use Scenario: Constant-current LED driver board powered from 220 V AC-derived DC bus, vulnerable to mains-coupled surges. IC Role / Device Role / Timing Role: Primary clamping element on bulk DC rail prior to buck converter stage. Use Value: 220 V nominal rating aligns with 220 VAC-derived ~310 VDC bus; 328 V VC prevents MOSFET drain overvoltage failure. | Use Scenario: Low-voltage analog interface (e.g., RS-485 receiver) connected to long external wiring in factory automation. IC Role / Device Role / Timing Role: Secondary-level protection behind gas discharge tube (GDT), absorbing residual energy after primary suppression. Use Value: Fast <1 ps response captures fast-rising EFT bursts (IEC 61000-4-4) that bypass slower primary protectors. |
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 SMAJ220A | Same DO-214AC (SMA) package; 220 V nominal, VC = 355 V @ 4.2 A; 400 W PPK rating | Lower surge rating suits less severe environments; surface-mount vs. axial DO-201 through-hole | Select when board space is constrained and 400 W surge margin suffices |
| ON Semiconductor 1.5SMC220A | DO-214AB (SMC) package; 220 V nominal, VC = 355 V @ 4.2 A; 1500 W PPK; same VBR range | Higher thermal mass than DO-201; compatible with automated SMT assembly | Choose for SMT production where DO-201 hand-soldering is undesirable |
Compared with 1.5KE220A R0G, SMAJ220A offers smaller footprint but lower surge capacity, while 1.5SMC220A matches 1500 W rating and VBR but uses SMC packaging - both require layout changes and differ in thermal mounting and mechanical robustness.

FAQ
What is the clamping voltage of the 1.5KE220A R0G under a standard 10/1000 µs surge?
The 1.5KE220A R0G has a maximum clamping voltage (VC) of 328 V at 4.8 A peak pulse current (IPP), measured using the 10/1000 µs waveform per IEC 61000-4-5. This value defines the highest voltage seen by downstream circuitry during a standardized surge event and is critical for ensuring protected components remain within absolute maximum ratings.
Is the 1.5KE220A R0G AEC-Q101 qualified?
No, the 1.5KE220A R0G is not AEC-Q101 qualified. The R0G suffix denotes standard commercial/industrial grade. For automotive applications requiring AEC-Q101 compliance, specify 1.5KE220A A0G - the same electrical specifications in DO-201 package with full AEC-Q101 qualification testing per the manufacturer's ordering matrix.
What is the working stand-off voltage (VWM) of the 1.5KE220A R0G, and why does it matter?
The 1.5KE220A R0G has a working stand-off voltage (VWM) of 185 V. This is the maximum DC or continuous peak voltage the device can block without exceeding 1 µA leakage current. It ensures reliable operation across normal system voltages (e.g., 220 VAC-derived DC buses) while maintaining high impedance until a damaging transient exceeds VBR.
How does the 1.5KE220A R0G compare to bidirectional TVS diodes like 1.5KE220CA?
The 1.5KE220A R0G is unidirectional and protects against positive transients only (anode-to-cathode), whereas 1.5KE220CA is bidirectional and clamps both polarities. Use 1.5KE220A R0G on DC lines with defined polarity (e.g., battery feeds); choose 1.5KE220CA for AC-coupled or floating signal lines where voltage reversals occur.
What is the thermal derating behavior of the 1.5KE220A R0G above 25°C ambient?
The 1.5KE220A R0G's peak pulse power (PPK) is derated linearly above TA = 25°C per Fig.2 in the datasheet: at 75°C ambient, PPK drops to ~75% of 1500 W (~1125 W); at 125°C, it falls to ~40% (~600 W). Derating applies to non-repetitive pulses - steady-state power dissipation remains 5 W only when mounted on a 16 mm × 16 mm copper pad at TL = 75°C.
