Product details
Overview
1.5KE220A A0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 220 V, working stand-off voltage 185 V, clamping voltage 328 V at 4.8 A peak impulse current, and junction temperature range −55 °C to +175 °C. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220A A0G datasheet, 1.5KE220A A0G pinout, 1.5KE220A A0G application, or 1.5KE220A A0G equivalent, key selection criteria include clamping performance under 10/1000 μs surge, low leakage (<1 μA above 10 V), AEC-Q101 qualification status, thermal derating behavior, and DO-201 mechanical compatibility with high-current PCB traces.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, triggering when transient voltage exceeds its 209–231 V breakdown range at 1 mA test current. Its 328 V clamping voltage at 4.8 A ensures downstream ICs see limited overvoltage during 1500 W, 10/1000 μs surges.
Designed for automotive and industrial environments, it meets ISO 7637-2 immunity requirements and supports steady-state power dissipation of 5 W at 75 °C lead temperature. The device exhibits <1 ps response time from 0 V to VBR, enabling protection of fast-edge digital and analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1 mA | 209–231 V - defines precise conduction onset threshold for reliable overvoltage detection |
| VWM | 185 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP = 4.8 A | 328 V - clamped voltage during full 1500 W surge, limiting stress on protected circuitry |
| IPP (10/1000 μs) | 4.8 A - peak impulse current capability under standard surge waveform |
| PPK | 1500 W - non-repetitive surge power rating at TA = 25 °C, derated above ambient |
| Junction Temp Range | −55 °C to +175 °C - enables operation in under-hood automotive and high-temp industrial enclosures |
| Leakage @ VWM | <1 μA - minimal standby power loss and negligible loading on high-impedance circuits |
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 reverse-biased operation | Connected to system ground or low-side return path; establishes reference for clamping action |
| Cathode | High-voltage input terminal | Connected to protected line (e.g., 24 V rail); conducts surge current to ground when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 328 V max at 4.8 A IPP - limits voltage overshoot to safe levels for 200 V-rated components |
| Surge robustness | 1500 W peak power (10/1000 μs) - withstands severe load-dump and inductive-switching events |
| Response speed | <1 ps rise time from 0 V to VBR - engages before most microsecond-scale transients fully develop |
| Automotive compliance | Meets ISO 7637-2 Pulse 1/2a/2b/3a/3b - validated for 12 V/24 V vehicle electrical systems |
| Environmental safety | RoHS compliant and halogen-free per IEC 61249-2-21 - satisfies modern environmental and fire-safety standards |
Applications

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; 220 V nominal, 328 V clamping at 4.3 A; lower PPK = 400 W | Lower surge rating suits consumer-grade 24 V systems but not automotive load-dump duty cycles | Select when space-constrained layouts require surface-mount and surge energy is ≤400 W |
| ON Semiconductor 1.5KE220A | Identical electrical specs and DO-201 package; same VBR, VC, IPP, and thermal ratings; RoHS/halogen-free compliant | No functional difference; qualified for identical ISO 7637-2 pulses and AEC-Q101 (when ordered with H suffix) | Drop-in second source with identical form, fit, and function; preferred for dual-sourcing programs |
Compared with Littelfuse SMAJ220A, the 1.5KE220A A0G delivers 3.75× higher surge power handling in through-hole format, while ON Semiconductor's 1.5KE220A offers exact parameter and mechanical equivalence-making it ideal for supply-chain diversification without design change.

FAQ
What is the clamping voltage of the 1.5KE220A A0G under a 10/1000 μs surge?
The 1.5KE220A A0G clamps to a maximum of 328 V when subjected to a 4.8 A peak impulse current under the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees predictable overvoltage limiting for downstream components. The 1.5KE220A A0G achieves this with low dynamic impedance, ensuring consistent clamping across production lots and temperature ranges.
Is the 1.5KE220A A0G AEC-Q101 qualified?
The base 1.5KE220A A0G part number is not AEC-Q101 qualified; qualification requires the "H" suffix (e.g., 1.5KE220AH). However, the 1.5KE220A A0G shares the same die and DO-201 construction as qualified variants and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements. For automotive production, specify 1.5KE220AH to ensure certified qualification documentation.
What is the maximum working stand-off voltage (VWM) for the 1.5KE220A A0G?
The 1.5KE220A A0G has a maximum working stand-off voltage (VWM) of 185 V, meaning it remains non-conductive with leakage <1 μA up to this DC or RMS voltage. This allows safe integration into 150–175 V DC systems such as telecom power feeds or industrial 200 V auxiliary rails, where margin above nominal voltage is required to avoid false triggering.
How does the 1.5KE220A A0G compare to bidirectional TVS diodes like 1.5KE220CA?
The 1.5KE220A A0G is unidirectional and intended for DC line protection with defined polarity, whereas 1.5KE220CA is bidirectional and suited for AC or floating signal lines. The 1.5KE220A A0G offers lower forward voltage drop (3.5 V @ 50 A) and tighter VBR tolerance (209–231 V) than its bipolar counterpart. Use the 1.5KE220A A0G when protecting grounded DC rails; choose 1.5KE220CA only for symmetrical surge threats.
What packaging options are available for the 1.5KE220A A0G?
The 1.5KE220A A0G is supplied in 500-piece ammo boxes (A0G suffix), compatible with manual or semi-automated through-hole assembly. It is not offered in tape-and-reel format-those variants use "H" or no suffix (e.g., 1.5KE220AH or 1.5KE220A). The DO-201 axial package has 0.375″ (9.5 mm) lead length and meets UL 94V-0 flammability rating.
