Product details
Overview
1.5KE200A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 200 V, minimum VBR = 190 V at IT = 1.0 mA, maximum clamping voltage VC = 274 V at IPP = 5.7 A, and working stand-off voltage VWM = 171 V - designed for high-energy surge protection in automotive power rails and industrial DC supplies.
For engineers reviewing the 1.5KE200A R0G datasheet, 1.5KE200A R0G pinout, 1.5KE200A R0G application, or 1.5KE200A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance status, junction temperature range (–55°C to +175°C), and real-world selection guidance against comparable 200 V TVS diodes.
Technical Context
The 1.5KE200A R0G operates as a unidirectional avalanche diode with fast response time (<1.0 ps from 0 V to VBR) and low dynamic impedance, enabling precise clamping during 10/1000 μs transients. Its VBR tolerance is ±5% (190–210 V), and temperature coefficient of VBR is 0.108 %/°C - critical for thermal stability in under-hood automotive environments.
It sustains 1500 W peak pulse power per JEDEC standard, derates linearly above 25°C ambient, and supports steady-state power dissipation of 5 W at lead temperature TL = 75°C on 0.6" × 0.6" copper pad. Forward voltage is 5.0 V max at IF = 50 A, confirming suitability for high-current inductive load suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V at IT = 1.0 mA - defines reliable avalanche initiation window for consistent clamping behavior |
| VWM | 171 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin below VBR |
| VC @ IPP | 274 V at IPP = 5.7 A - peak clamped voltage during 10/1000 μs surge; determines protected circuit's voltage stress limit |
| PPK | 1500 W - peak pulse power handling per single 10/1000 μs waveform; enables robust protection against ISO 7637-2 pulses |
| Junction Temp | –55°C to +175°C - extended thermal range supports under-hood automotive and industrial power supply use |
| Package | DO-201 - axial-leaded, UL 94V-0 molded case with pure tin-plated leads; compatible with wave and reflow soldering per J-STD-002 |
| Leakage @ VWM | <1 µA - ensures minimal standby current draw in always-on systems such as vehicle body control modules |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy-molded case with cathode band marking for unidirectional polarity. Cathode end is marked; anode is unmarked. 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 (unmarked end) | Current entry point in forward bias; connected to system ground or low-side return path | Enables low-VF conduction during inductive turn-off events; must be routed to lowest-impedance ground plane |
| Cathode (banded end) | Current exit point in forward bias; connected to protected line (e.g., 24 V rail) | Clamps transients by shunting surge current to ground when line voltage exceeds VBR; polarity must match PCB silkscreen |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; R0G suffix indicates green, halogen-free, RoHS-compliant variant |
| 1500 W surge rating at 10/1000 μs | Meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) requirements |
| Clamping voltage ≤274 V at 5.7 A | Ensures downstream 300 V-rated components (e.g., MOSFETs, regulators) remain within safe operating area during worst-case surge |
| Leakage <1 µA above 10 V | Minimizes quiescent power loss in battery-backed systems and avoids false triggering in high-impedance sensing circuits |
| Fast response <1.0 ps | Activates before transient edge propagates across PCB traces - essential for protecting high-speed interface ICs near connectors |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Suppressing load dump transients (ISO 7637-2 Pulse 5a) on 24 V vehicle battery lines feeding ECUs and ADAS sensors. IC Role / Device Role: Primary overvoltage clamp placed directly at connector entry point, upstream of DC-DC converters and LDOs. Use Value: Limits voltage excursion to ≤274 V, preventing damage to 300 V-rated input capacitors and gate drivers in motor control units. |
Use Scenario: Protecting programmable logic controllers (PLCs) from switching surges induced by relay coils and solenoid valves in factory automation. IC Role / Device Role: Unidirectional TVS installed across 24/48 V DC input terminals to absorb repetitive inductive kickback energy. Use Value: Withstands ≥1000 surges at rated PPK, eliminating need for frequent replacement in high-cycle industrial environments. |
| LED Driver Overvoltage Clamp | Telecom Power Interface |
Use Scenario: Safeguarding constant-current LED drivers in street lighting against lightning-induced surges on long outdoor wiring runs. IC Role / Device Role: Secondary protection stage after MOV-based primary clamp, providing precise low-leakage clamping near driver IC inputs. Use Value: Sub-1 µA leakage prevents false dimming or shutdown in always-on lighting systems; DO-201 allows through-hole mounting on high-voltage PCBs. |
Use Scenario: Shielding PoE-powered equipment (e.g., IP cameras, wireless APs) from Ethernet cable ESD and induced surges. IC Role / Device Role: Line-to-ground TVS on DC input side of PoE PD controller, complementing data-line protection. Use Value: 274 V clamping ensures compatibility with IEEE 802.3af/at 57 V max input while surviving 1500 W common-mode surges. |
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 200 V nominal, DO-214AC (SMA) package; lower PPK = 400 W; VC = 324 V at IPP = 1.2 A | Not suitable for ISO 7637-2 Pulse 1; limited to lower-energy ESD/lightning secondary protection | Select only if space-constrained layout prohibits DO-201 and surge energy is ≤400 W |
| ON Semiconductor 1.5SMC200A | Same 200 V rating, DO-214AB (SMC) package; PPK = 1500 W; VC = 274 V at IPP = 5.7 A; identical clamping but larger footprint | Compatible with same surge standards but requires 2.5× more PCB area than DO-201 | Choose when higher thermal mass is needed for repeated surge duty cycles; verify board cutout clearance for SMC outline |
Compared with 1.5KE200A R0G, SMAJ200A offers smaller size but sacrifices 73% peak power handling and clamps 50 V higher - making it inadequate for automotive load dump. 1.5SMC200A matches performance exactly but demands larger PCB real estate and different assembly tooling.

FAQ
What is the exact breakdown voltage range for 1.5KE200A R0G?
The 1.5KE200A R0G has a guaranteed breakdown voltage range of 190 V to 210 V at test current IT = 1.0 mA, per Taiwan Semiconductor's O2104 datasheet revision. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes from –55°C to +175°C.
Does 1.5KE200A R0G meet AEC-Q101 qualification?
The 1.5KE200A R0G itself is not AEC-Q101 qualified; however, the 1.5KE200AH variant (with "H" suffix) is explicitly listed as AEC-Q101 qualified in the ordering information table. R0G denotes RoHS-compliant, halogen-free green compound - a material attribute, not a qualification level.
What is the maximum clamping voltage of 1.5KE200A R0G under surge conditions?
The maximum clamping voltage VC of 1.5KE200A R0G is 274 V at peak impulse current IPP = 5.7 A, measured using the standard 10/1000 μs double-exponential waveform. This value is confirmed in the Electrical Specifications table on page 3 of the Taiwan Semiconductor 1.5KE series datasheet (O2104).
Can 1.5KE200A R0G be used in bidirectional configurations?
No - 1.5KE200A R0G is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., 1.5KE200CA). Using 1.5KE200A R0G in reverse-biased mode risks permanent failure due to lack of symmetric avalanche structure.
What is the thermal derating behavior of 1.5KE200A R0G above 25°C ambient?
1.5KE200A R0G follows a linear derating curve: peak pulse power PPK decreases from 1500 W at 25°C to zero at 175°C junction temperature. Derating is defined in Fig.2 of the datasheet - e.g., at 100°C ambient (with heat sink), PPK is reduced to ~900 W, requiring careful thermal design in enclosed automotive enclosures.
