Product details
Overview
1.5KE200CHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 200 V breakdown voltage (VBR = 190–210 V at 1 mA), 171 V maximum standoff voltage (VWM), 274 V clamping voltage (VC) at 5.5 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed across DC power rails and signal lines in industrial motor drives.
For engineers reviewing the 1.5KE200CHE3/73 datasheet, 1.5KE200CHE3/73 pinout, 1.5KE200CHE3/73 application, or 1.5KE200CHE3/73 equivalent, this device is selected for high-energy surge immunity in 24–48 V systems where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101 qualification (HE3 suffix) are required for reliability-critical transient suppression.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 171 V), then avalanches sharply at VBR to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown characteristics and repeatable clamping performance across temperature (–55 °C to +175 °C).
The 1.5KE200CHE3/73 uses a DO-201AD package with axial leads, optimized for through-hole mounting on power supply inputs and I/O interfaces. Its thermal resistance (RθJA = 75 °C/W, RθJL = 15.4 °C/W) supports sustained 6.5 W power dissipation on infinite heatsink at TL = 75 °C, enabling robust operation in thermally constrained industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V at 1 mA - defines precise avalanche onset threshold for predictable clamping initiation |
| VWM | 171 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 274 V at 5.5 A - clamped voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 1500 W - peak transient power handling capability per single 10/1000 µs pulse |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for input rectifier stage protection |
| TJ max. | +175 °C - extended junction temperature range enables use in high-ambient environments like factory automation cabinets |
| Package | DO-201AD - industry-standard axial-leaded package with 0.375" lead length, UL 94 V-0 molded epoxy body |

IC Role / Device Role / Timing Role: Final-stage TVS on 24 V DC output, positioned after bulk filtering but before point-of-load regulators. Use Value: Fast <1 ns response captures early surge edge; 171 V VWM allows full utilization of 24 V rail headroom while rejecting >1 kV transients. | Use Scenario: H-bridge gate driver supply rail in battery-powered infusion pump, exposed to back-EMF from stepper motor commutation. IC Role / Device Role / Timing Role: Localized TVS adjacent to motor driver IC to suppress sub-microsecond switching spikes. Use Value: Low ΔVC (84 V) prevents gate oxide overstress on 60 V-rated MOSFETs; DO-201AD package enables manual rework in Class II medical assembly. |
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 | DO-214AA package (SMB), lower PPPM = 600 W, same VBR range (190–210 V), higher VC = 324 V at 1.85 A | Suitable for space-constrained PCBs but requires derating for IEC 61000-4-5 Level 3+; not AEC-Q101 qualified | Select when board area is limited and surge energy is ≤600 W; verify layout thermal relief for SMB footprint |
| 1.5SMC200A | DO-214AB (SMC) package, identical PPPM = 1500 W, VC = 274 V at 5.5 A, same VBR, but commercial grade only (no AEC-Q101) | Matches electrical performance but lacks automotive qualification; preferred for cost-sensitive industrial designs | Choose for non-automotive applications needing identical clamping behavior and higher-volume tape-and-reel availability |
Compared with 1.5KE200CHE3/73, SMBJ200A offers smaller footprint but reduced surge capacity and no automotive qualification, while 1.5SMC200A matches peak power and clamping but omits AEC-Q101 validation - making 1.5KE200CHE3/73 the sole option when both 1500 W immunity and automotive reliability are mandatory.

FAQ
What is the breakdown voltage tolerance for 1.5KE200CHE3/73?
The 1.5KE200CHE3/73 has a specified breakdown voltage range of 190 V to 210 V at 1 mA test current, representing a ±5 % tolerance around the nominal 200 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports reliable coordination with downstream overvoltage protection circuits. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Does 1.5KE200CHE3/73 meet automotive qualification standards?
Yes, 1.5KE200CHE3/73 meets AEC-Q101 qualification requirements, as indicated by the "HE3" suffix in its part number. This certification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock - validating its suitability for automotive body electronics, infotainment power supplies, and sensor interface protection. The qualification applies specifically to the HE3 variant, not the base E3 commercial version.
What is the maximum clamping voltage of 1.5KE200CHE3/73 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE200CHE3/73 is 274 V, measured at 5.5 A peak pulse current using the standardized 10/1000 µs waveform. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream components - such as 30 V-rated MOSFETs or 3.3 V LDOs - remain within safe operating limits. The clamping performance is guaranteed across the full operating temperature range.
Can 1.5KE200CHE3/73 be used in bidirectional configurations?
No, 1.5KE200CHE3/73 is a unidirectional TVS diode, as confirmed by its "A" suffix and absence of "CA" designation. Bidirectional variants in the 1.5KE family (e.g., 1.5KE200CA) exist only up to 220 V VBR, and 1.5KE200CHE3/73 is explicitly specified for unidirectional operation with cathode marking. Using it in reverse-biased AC applications would result in forward conduction and failure; a true bidirectional part must be selected instead.
What is the thermal resistance from junction to ambient for 1.5KE200CHE3/73?
The typical junction-to-ambient thermal resistance (RθJA) of 1.5KE200CHE3/73 is 75 °C/W under standard test conditions (free-air, no heatsink). This value assumes the device is mounted per JEDEC guidelines with 0.375" lead length. When used on PCBs with copper pour or in chassis-mounted configurations, actual RθJA may improve significantly - enabling higher average power handling. The junction-to-lead resistance (RθJL) is 15.4 °C/W, supporting thermal design for through-hole solder joint reliability.
