Product details
Overview
1.5KE200A A0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 200V, clamping voltage 274V at 5.7A peak pulse current, and working stand-off voltage 171V. 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 1.5KE200A A0G datasheet, 1.5KE200A A0G pinout, 1.5KE200A A0G application, or 1.5KE200A A0G equivalent, this page delivers verified electrical parameters, DO-201 terminal mapping, real-world protection use cases, and two validated alternative parts for ESD and surge immunity design.
Technical Context
The 1.5KE200A A0G operates as a unidirectional avalanche diode with 200V nominal breakdown (190–210V min/max at 1mA test current), 171V maximum working stand-off voltage, and 274V clamping voltage under 5.7A 10/1000μs surge. Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment.
It delivers 1500W non-repetitive peak pulse power per JEDEC standard, exhibits <1μA leakage above 10V, and features low dynamic impedance enabling fast response (<1.0ps from 0V to VBR). The device meets AEC-Q101 qualification when ordered with "H" suffix, though 1.5KE200A A0G itself is standard-grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 190–210V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 171V - maximum continuous reverse operating voltage before leakage exceeds 1μA |
| VC @ IPP = 5.7A | 274V - clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPK | 1500W - peak surge power handling capability per single 1ms pulse |
| Junction Temp Range | −55°C to +175°C - enables operation in engine control units and industrial motor drives |
| Package | DO-201 - axial-leaded, UL 94V-0 molded case with tin-plated leads per J-STD-002 |
| Leakage @ VWM | <1μA - ensures minimal standby power loss in always-on systems |
Pinout & Package
DO-201 package: axial leaded, cylindrical epoxy body with cathode band marking. Cathode (K) is marked by a band; anode (A) is unmarked end. Leads are pure tin-plated, solderable per J-STD-002, and pass JESD201 Class 2 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| 1500W surge rating | Withstands ISO 7637-2 Pulse 2b (inductive load dump) without degradation |
| Clamping voltage 274V | Keeps protected 200V-rated components below absolute maximum ratings during 5.7A surge |
| Response time <1.0ps | Activates faster than most microsecond-scale transients, preventing latch-up in MCU I/O |
| Low leakage <1μA | Minimizes quiescent current in battery-backed sensors and always-on CAN nodes |
| DO-201 mechanical robustness | UL 94V-0 flammability rating and 0.090g mass support high-vibration environments |
Applications
| Automotive Power Rail Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 12V/24V vehicle battery line exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges before reaching PMIC or MCU power supply pins.

IC Role / Device Role / Timing Role: Standoff protector on input line, absorbing EFT bursts (IEC 61000-4-4) and electrostatic discharge events. Use Value: Prevents false triggering and latch-up in optocoupler input stages with <1μA leakage preserving signal integrity. |
| Motor Drive Gate Driver Protection | Telecom DC Power Feeding Line |
Use Scenario: High-side gate driver supply rail in BLDC inverter subject to inductive switching spikes. IC Role / Device Role / Timing Role: Clamps flyback-induced voltage overshoot across gate driver's VDD-to-GND path. Use Value: Maintains gate driver functionality by holding VDD within 274V, avoiding internal overvoltage shutdown. | Use Scenario: −48V DC feeding line in telecom base station equipment exposed to lightning-induced surges.

Use Value: Provides precise 274V clamping level compatible with −53V nominal telecom rail, minimizing let-through energy. |
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 SMAJ200A | Same 200V VBR, DO-214AC (SMA) package, 600W PPK, higher leakage (5μA @ VWM) | Lower surge rating limits use to lower-energy transients (e.g., IEC 61000-4-2 ESD only) | Select when board space is constrained and 600W suffices; not suitable for ISO 7637-2 Pulse 2b. |
| ON Semiconductor 1N6267A | 6.8V VBR, DO-201, 1500W - same family but incompatible voltage grade | Designed for low-voltage logic-level protection, not 200V rail clamping | Not interchangeable; only relevant for redesigning protection at different voltage nodes. |
Compared with 1.5KE200A A0G, SMAJ200A offers smaller footprint but sacrifices 60% surge capacity and has higher leakage, while 1N6267A serves entirely different voltage domains and cannot substitute in 200V applications.

Manufacturer

The 1.5KE series was designed specifically for high-energy transient suppression in harsh environments-emphasizing robust DO-201 packaging, AEC-Q101 qualification paths, and compliance with ISO 7637-2 and IEC 61000-4-x immunity standards.
FAQ
What is the clamping voltage of the 1.5KE200A A0G under a 10/1000μs surge?
The 1.5KE200A A0G clamps to a maximum of 274V when subjected to a 5.7A peak pulse current with 10/1000μs waveform. This value is measured per JEDEC test conditions and guarantees that downstream components see no more than 274V during standardized surge events, making it suitable for protecting 300V-rated capacitors and 200V-input regulators in automotive and industrial systems. The 1.5KE200A A0G achieves this with low dynamic impedance and sub-nanosecond response.
Is the 1.5KE200A A0G AEC-Q101 qualified?
No, the 1.5KE200A A0G is not AEC-Q101 qualified. The "A0G" suffix denotes DO-201 packaging in 500-piece ammo box packaging; AEC-Q101 qualification requires the "H" suffix (e.g., 1.5KE200AH). While the 1.5KE200A A0G shares the same die and DO-201 construction, only variants explicitly ordered with "H" undergo the full stress-test sequence per AEC-Q101. For automotive under-hood applications requiring qualification, specify 1.5KE200AH instead of 1.5KE200A A0G.
What is the maximum working stand-off voltage (VWM) for the 1.5KE200A A0G?
The maximum working stand-off voltage (VWM) for the 1.5KE200A A0G is 171V. This is the highest DC or continuous reverse voltage the device can withstand without exceeding 1μA leakage current. It ensures reliable blocking during normal operation of 170V-class systems-such as telecom −48V feed lines with high common-mode noise-while still allowing margin for the 190–210V breakdown range. Exceeding 171V risks premature conduction and thermal runaway in the 1.5KE200A A0G.
Can the 1.5KE200A A0G be used in bidirectional configurations?
No, the 1.5KE200A A0G is a unidirectional TVS diode and must not be used in bidirectional configurations. Its cathode band marks the surge-current sink terminal, and reverse-bias operation beyond VWM triggers clamping only in one polarity. For bidirectional protection (e.g., AC lines or differential data buses), select the CA-suffixed variant (1.5KE200CA) or a dedicated bidirectional TVS. Using 1.5KE200A A0G in place of a bidirectional part leaves one polarity unprotected and may cause catastrophic failure during negative transients.
What package type does the 1.5KE200A A0G use, and what are its key mechanical attributes?
The 1.5KE200A A0G uses the DO-201 axial-leaded package: cylindrical epoxy body with cathode band marking, UL 94V-0 flammability rating, pure tin-plated leads compliant with J-STD-002 solderability, and JESD201 Class 2 whisker resistance. Its weight is approximately 0.090g, and lead spacing matches standard through-hole footprints. This package supports high-reliability mounting in vibration-prone environments-critical for the 1.5KE200A A0G's intended use in automotive and industrial power protection.
