Product details
Overview
1.5KE200-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 200 V breakdown voltage (VBR = 190–210 V at 1 mA), 171 V standoff voltage (VWM), 274 V clamping voltage (VC) at 5.5 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +175 °C. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE200-E3/73 datasheet, 1.5KE200-E3/73 pinout, 1.5KE200-E3/73 application, or 1.5KE200-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating curves, and direct alternatives with documented differences in breakdown tolerance, polarity, and AEC-Q101 qualification status.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse power rating is defined per 10/1000 µs waveform with 0.01% duty cycle, and it maintains stable clamping performance across –55 °C to +175 °C junction temperature range.
It exhibits a maximum reverse leakage of 1.0 µA at 171 V standoff, forward voltage of 5.0 V at 100 A (per note 3), and thermal resistance of 15.4 °C/W (junction-to-lead). The device is RoHS-compliant (E3 suffix), commercial-grade, and not AEC-Q101 qualified - unlike HE3-suffixed variants in the same family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V at 1 mA - defines reliable conduction onset under transient stress |
| VWM | 171 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 274 V at 5.5 A - clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak transient energy absorption capability without failure |
| IFSM | 200 A (8.3 ms half-sine) - surge current handling for unidirectional forward conduction events |
| TJ max. | +175 °C - enables use in high-temperature environments such as engine compartments or enclosed power supplies |
| Package | JEDEC DO-201AD (Case Style 1.5KE) - axial-leaded, epoxy-molded, UL 94 V-0 rated body |
Pinout & Package
1.5KE200-E3/73 uses the standard DO-201AD axial package (Case Style 1.5KE), with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity is marked by a cathode band; the banded end is the cathode (K), and the unmarked end is the anode (A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry terminal in forward bias | Connects to lower-potential side of protected line; enables clamping when cathode voltage exceeds VBR |
| Cathode (K) | Current exit terminal in forward bias; high-impedance node in reverse standby | Banded end; connects to higher-potential rail (e.g., VCC, signal line); conducts only during overvoltage events |
Key Features
| Feature | Design Value |

Applications
| Industrial Motor Drives | Automotive Power Distribution |
|---|---|
Use Scenario: Protection of gate drivers and MCU I/O against back-EMF spikes from relay and solenoid switching in PLCs and CNC controllers. IC Role / Device Role: Unidirectional TVS placed between VDD and GND on 24 V auxiliary supply rails. Use Value: Limits transient excursions to ≤274 V, preventing latch-up or oxide rupture in 3.3 V/5 V logic and 600 V IGBT gate drivers. |

IC Role / Device Role: Primary overvoltage suppressor on main power input, upstream of DC-DC converters. Use Value: Withstands 1500 W surges up to 175 °C ambient, meeting ISO 7637-2 Pulse 5a requirements without derating. |
| Telecom Line Interface | Consumer Appliance Control Boards |
Use Scenario: Surge suppression on RS-485 or Ethernet PHY power rails exposed to induced lightning on outdoor cabling. IC Role / Device Role: Standoff-rated TVS on isolated 3.3 V or 5 V bias rails feeding communication ICs. Use Value: 171 V VWM ensures no leakage or power loss during normal operation; 274 V VC prevents damage to PHY transceivers rated to 30 V abs max. |
Use Scenario: Protecting microcontroller reset lines and sensor inputs in washing machines and HVAC control units. IC Role / Device Role: Low-leakage (≤1 µA) unidirectional clamp on 3.3 V/5 V rails subject to ESD and relay bounce. Use Value: Sub-ns response prevents false resets or ADC corruption; DO-201AD package allows manual rework and high-reliability through-hole mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE200AHE3_B | AEC-Q101 qualified; identical VBR, VWM, VC, and PPPM; HE3 suffix denotes whisker-tested, automotive-grade variant | Approved for automotive powertrain and chassis modules requiring AEC-Q101 validation | Select when automotive qualification, extended temperature validation, or enhanced process traceability is required |
| SMBJ200A | DO-214AA package (SMB); lower PPPM (600 W); same VBR (190–210 V); higher VC (324 V @ 1.85 A) | Suitable for space-constrained PCBs where 1500 W is not mandatory; not drop-in due to footprint and surge rating mismatch | Choose for compact surface-mount designs accepting reduced surge margin and higher clamping voltage |
Compared with 1.5KE200-E3/73, the 1.5KE200AHE3_B adds automotive qualification without altering electrical specs, while SMBJ200A trades surge capacity and package form factor for board area savings - neither is pin-compatible, but both serve distinct design priorities in overvoltage protection architecture.

FAQ
What is the breakdown voltage tolerance for 1.5KE200-E3/73?
The 1.5KE200-E3/73 has a guaranteed breakdown voltage range of 190 V to 210 V at 1 mA test current, per Vishay Document 88301. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, enabling precise coordination with downstream overvoltage thresholds in 1.5KE200-E3/73-based protection schemes.
Is 1.5KE200-E3/73 bidirectional or unidirectional?
The 1.5KE200-E3/73 is a unidirectional TVS diode, indicated by the absence of "C" in its part number. It conducts only when cathode voltage exceeds anode voltage by ≥190 V. Bidirectional variants (e.g., 1.5KE200CA) exist in the same family but are separate orderables - 1.5KE200-E3/73 must not be substituted for bidirectional use without circuit redesign.
Does 1.5KE200-E3/73 meet AEC-Q101 requirements?
No, 1.5KE200-E3/73 is commercial-grade only. AEC-Q101 qualification applies only to HE3-suffixed variants like 1.5KE200AHE3_B. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, but does not imply automotive qualification. For automotive applications, specify the HE3 version explicitly - 1.5KE200-E3/73 is not approved for AEC-Q101 use.
What is the clamping voltage of 1.5KE200-E3/73 at rated surge current?
At its rated peak pulse current of 5.5 A (10/1000 µs waveform), the 1.5KE200-E3/73 clamps to a maximum of 274 V. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during worst-case transients - a critical parameter for ensuring 1.5KE200-E3/73 remains within safe operating area of downstream ICs.
Can 1.5KE200-E3/73 replace 1.5KE220A in the same footprint?
No - although both use DO-201AD packaging, 1.5KE200-E3/73 (VBR = 190–210 V) and 1.5KE220A (VBR = 209–231 V) have non-overlapping breakdown ranges. Substituting them risks either premature clamping (if VBR is too low) or insufficient protection (if VBR is too high). Always verify system-level coordination using actual 1.5KE200-E3/73 VBR and VC values before replacement.
