Product details
Overview
1.5KE220CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 220 V breakdown voltage (VBR = 209–231 V at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, and operates across –55 °C to +175 °C. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in industrial and automotive systems.
For engineers reviewing the 1.5KE220CAHE3_B/C datasheet, 1.5KE220CAHE3_B/C pinout, 1.5KE220CAHE3_B/C application, or 1.5KE220CAHE3_B/C equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified (HE3 suffix), surface-mountable TVS with verified bidirectional clamping, low incremental surge resistance, and UL 94 V-0 molded epoxy packaging - critical for robust ESD and surge immunity design validation.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and stable clamping under repetitive 10/1000 µs surges at 0.01% duty cycle. Its bidirectional architecture eliminates polarity sensitivity, enabling symmetric protection on AC lines or differential buses without orientation constraints.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting reliable operation up to TJ = 175 °C. The device sustains 200 A unidirectional IFSM (8.3 ms half-sine), though 1.5KE220CAHE3_B/C is bidirectional-only and thus excludes forward surge rating per datasheet note.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 209–231 V at 1 mA - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 185 V max - ensures no conduction during normal 180 VAC line peaks or 200 VDC system rails |
| Clamping Voltage VC | 328 V at 4.6 A (10/1000 µs) - limits transient voltage seen by downstream circuitry |
| Peak Pulse Power PPPM | 1500 W - withstands IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without failure |
| Operating Temperature | –55 °C to +175 °C - supports under-hood automotive and industrial ambient environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with matte tin-plated leads, UL 94 V-0 compliant |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), higher VC (356 V @ 4.2 A) | Preferred for space-constrained PCBs; unsuitable for IEC 61000-4-5 Level 4 | Select when board area is critical and surge levels are ≤1 kV |
| 1.5SMC220CA | Same PPPM (1500 W), SMC package (DO-214AB), slightly higher VC (339 V @ 4.4 A), same VBR range | Surface-mount alternative with comparable thermal performance; requires different footprint | Choose for automated assembly where through-hole mounting is impractical |
Compared with 1.5KE220CAHE3_B/C, SMBJ220CA trades peak power and ruggedness for compactness, while 1.5SMC220CA matches power handling but shifts to SMT - making the original optimal for high-reliability through-hole designs requiring AEC-Q101 validation and proven DO-201AD mechanical robustness.

FAQ
What is the breakdown voltage tolerance for 1.5KE220CAHE3_B/C?
The 1.5KE220CAHE3_B/C has a specified breakdown voltage (VBR) range of 209 V to 231 V at 1 mA test current, representing a ±5% tolerance around the nominal 220 V rating. This tight tolerance ensures consistent clamping behavior across production lots and enables predictable system-level surge margining without derating overhead.
Is 1.5KE220CAHE3_B/C suitable for automotive applications?
Yes, 1.5KE220CAHE3_B/C is AEC-Q101 qualified (denoted by the HE3 suffix) and rated for operation from –55 °C to +175 °C. It meets automotive requirements for surge immunity, thermal cycling, and humidity testing - making it appropriate for use in body control modules, infotainment power supplies, and sensor interface protection within passenger vehicles and commercial fleets.
How does the bidirectional design of 1.5KE220CAHE3_B/C affect its placement on the PCB?
The bidirectional nature of 1.5KE220CAHE3_B/C means it has no polarity marking and functions identically regardless of orientation. This simplifies PCB layout by eliminating cathode/anode alignment checks - especially valuable on AC-coupled lines like RS-485, CAN, or transformer-isolated power inputs where voltage polarity reverses during normal operation.
What is the maximum clamping voltage of 1.5KE220CAHE3_B/C under surge conditions?
The maximum clamping voltage (VC) of 1.5KE220CAHE3_B/C is 328 V when subjected to its rated peak pulse current of 4.6 A using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients and is critical for ensuring downstream components remain within their absolute maximum ratings.
Does 1.5KE220CAHE3_B/C require a heatsink for standard operation?
No, 1.5KE220CAHE3_B/C does not require an external heatsink under typical surge conditions because its 1500 W rating applies to short-duration pulses (≤1 ms), not continuous dissipation. Its steady-state power dissipation is limited to 6.5 W on an infinite heatsink, and normal operation involves only transient energy absorption - not sustained thermal loading.
