Product details
Overview
1.5KE200AG from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 171 V working peak reverse voltage (VRWM), 200 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤324 V at 4.6 A peak pulse current (IPP), making it suitable for industrial power supply input stage surge protection.
For engineers reviewing the 1.5KE200AG datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected circuit's absolute maximum rating, VRWM compatibility with DC bus voltage, UL 497B recognition for isolated loop circuits, and axial leaded Surmetic package suitability for through-hole PCB layouts requiring high surge robustness.
Technical Context
This device operates as a silicon avalanche diode with fast <1 ns response time and low dynamic impedance, enabling effective suppression of sub-microsecond transients. Its unidirectional configuration provides reverse-biased clamping only, requiring correct polarity installation with cathode connected toward the protected circuit's higher potential side.
The 1.5KE200AG is rated for 1500 W non-repetitive peak pulse power (1 ms, 10/1000 µs waveform), 5.0 W steady-state dissipation at 75°C lead temperature, and exhibits <5 µA leakage above 10 V - critical for low-power standby circuits. Thermal resistance junction-to-lead is 20°C/W, supporting reliable heat transfer via PCB copper pour or heatsinking leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 171 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC bus or signal swing. |
| VBR @ IT=1 mA | 200 V (min) to 210 V (max) - Avalanche onset threshold; defines minimum clamping initiation point. |
| VC @ IPP=4.6 A | ≤324 V - Maximum clamped voltage during 1500 W surge; determines worst-case overvoltage seen by downstream ICs. |
| IPP | 4.6 A - Peak pulse current capability at 1 ms; defines maximum transient energy absorption per event. |
| Leakage @ VRWM | <5 µA - Negligible standby current draw; avoids loading low-power sensor or control circuits. |
| Response Time | <1 ns - Enables suppression of fast-rising ESD events before protected components experience overstress. |
| UL Recognition | UL 497B QVGQ2 - Certified for isolated loop circuit protection; validates reliability under standardized surge endurance testing. |
Pinout & Package
1.5KE200AG uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a colored band. Leads are tin-plated, solderable at 260°C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection terminal | Connected to ground or lowest potential node; carries full surge return current. |
| Cathode | High-side connection terminal | Marked with band; connects to protected line (e.g., AC input, DC rail); blocks forward current during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges on industrial AC mains inputs. |
| UL 497B certification | Validates compliance for telecom and process control isolated loop interfaces without additional safety qualification effort. |
| ESD rating >16 kV HBM | Provides built-in handling robustness during assembly and field service, reducing pre-deployment failure risk. |

Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: AC/DC front-end of programmable logic controllers (PLCs) exposed to 4 kV lightning-induced surges on 24 V DC auxiliary rails. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed across input terminals to limit transient voltage before it reaches upstream rectifier and downstream DC-DC controller. Use Value: Clamping to ≤324 V ensures protected 40 V-rated input capacitors and 36 V max-rated controller ICs remain within safe operating area during surge events. | Use Scenario: RS-485 data lines in building automation systems subjected to induced surges from nearby HVAC motor switching. IC Role / Device Role / Timing Role: Parallel-connected TVS on differential pair (A/B) referenced to local ground, absorbing common-mode transients before receiver inputs. Use Value: <1 ns response prevents data corruption during fast edge transitions; UL 497B certification satisfies isolation barrier requirements for Class 2 wiring. |
| Medical Equipment Mains Filtering | Process Control Sensor Signal Conditioning |
Use Scenario: Secondary-side 48 V DC distribution network in diagnostic imaging equipment where EMI filters require coordinated surge protection. IC Role / Device Role / Timing Role: TVS installed after EMI filter but before DC-DC modules to prevent filter capacitor overstress and ensure clean shutdown during surge. Use Value: 171 V VRWM matches nominal 48 V system with 3× safety margin; low leakage avoids false triggering of low-current fault detection circuits. | Use Scenario: 4–20 mA current loop transmitter outputs in chemical plant analyzers exposed to ground potential differences. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional 1.5KE200AG placed between loop+ and ground to clamp positive transients from cable coupling. Use Value: Axial package allows direct mounting near terminal block; 324 V clamping preserves 36 V-rated op-amp input stages and ADC reference integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Surface-mount SMB package; 200 V VRWM; 324 V VC @ 4.6 A; same clamping performance but lower 600 W peak power rating. | Requires PCB redesign for SMT layout; unsuitable for high-reliability through-hole assemblies or high-temperature environments exceeding 150°C junction. | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 3 (2 kV). |
| 1.5KE200A | Identical electrical specs and package; differs only in Pb-free compliance - "G" suffix confirms RoHS-compliant plating vs. legacy SnPb finish. | No functional or mechanical difference; both share same UL 497B recognition and thermal derating curves. | Choose 1.5KE200AG for new designs requiring RoHS compliance and modern soldering processes. |
Compared with SMBJ200A, 1.5KE200AG delivers 2.5× higher surge energy handling in a mechanically robust axial package ideal for industrial field wiring; versus 1.5KE200A, it guarantees Pb-free construction without compromising surge immunity or thermal performance.

FAQ
What is the clamping voltage of the 1.5KE200AG under maximum surge conditions?
The 1.5KE200AG clamps to a maximum of 324 V when subjected to its rated 4.6 A peak pulse current (IPP), corresponding to a 1500 W, 1 ms transient. This value is measured per the standard 10/1000 µs double-exponential waveform and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must verify that this clamping voltage remains below the absolute maximum ratings of downstream components.
Does the 1.5KE200AG meet UL safety standards for industrial isolation barriers?
Yes, the 1.5KE200AG is UL Recognized under standard UL 497B (File #E210057, category QVGQ2) for protector applications in isolated loop circuits. This certification covers endurance, dielectric withstand, discharge, and strike voltage breakdown testing - confirming suitability for use in safety-critical industrial communication interfaces such as 4–20 mA loops and RS-485 networks without additional system-level validation.
How does the 1.5KE200AG differ from the 1.5KE200A variant?
The 1.5KE200AG and 1.5KE200A share identical electrical specifications, package dimensions, and thermal performance. The sole difference is RoHS compliance: the "G" suffix in 1.5KE200AG denotes a Pb-free lead finish compatible with modern lead-free soldering processes, whereas 1.5KE200A uses traditional SnPb plating. Both parts carry UL 497B recognition and are mechanically interchangeable in through-hole assemblies.
Can the 1.5KE200AG be used for bidirectional transient protection?
No, the 1.5KE200AG is a unidirectional TVS diode and conducts only in reverse breakdown - it cannot suppress positive transients on grounded lines or negative excursions on floating nodes. For bidirectional protection, a dedicated bidirectional part (e.g., 1.5KE200CA) or back-to-back unidirectional configuration is required. Using 1.5KE200AG in reverse polarity risks permanent forward conduction and device failure.
What is the maximum allowable steady-state power dissipation for the 1.5KE200AG?
The 1.5KE200AG has a steady-state power dissipation rating of 5.0 W at a lead temperature (TL) of 75°C, with linear derating to zero at 175°C. At ambient temperatures above 75°C, power must be reduced at 20 mW/°C. This rating applies only to continuous DC or low-frequency AC stress - not transient surges - and assumes adequate PCB copper area or heatsinking to maintain specified lead temperature.
