Product details
Overview
1.5KE220CA 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 junction temperature. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in industrial and automotive systems.
For engineers reviewing the 1.5KE220CA datasheet, 1.5KE220CA pinout, 1.5KE220CA application, or 1.5KE220CA equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, UL 94 V-0 molded package details, and AEC-Q101-qualified alternatives - all critical for robust overvoltage design validation and BOM selection.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating circuits without polarity constraints, unlike unidirectional variants requiring cathode orientation.
It complies with ANSI/IEEE C62.35 surge standards and supports repetitive 10/1000 µs waveform testing at 0.01% duty cycle. Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation up to TJ = 175 °C with appropriate PCB copper area or lead-length thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1 mA - defines precise voltage threshold where clamping initiates under transient stress |
| VWM | 185 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe DC bias margin |
| VC @ IPPM | 328 V at 4.6 A - clamped voltage during full 1500 W surge; determines protected circuit's worst-case overvoltage exposure |
| PPPM | 1500 W - peak pulse power handling per 10/1000 µs waveform; validates immunity to IEC 61000-4-5 Level 4 surges |
| TJ range | –55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with matte tin-plated leads, UL 94 V-0 epoxy body, and JESD 22-B102 solderability |
| Leakage @ VWM | <1 µA - ensures negligible standby current in high-impedance sensor or battery-backed circuits |
Pinout & Package
1.5KE220CA is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package with no polarity marking - consistent with its bidirectional function. Leads are matte tin-plated and compliant with J-STD-002 and JESD 22-B102 soldering standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between leads; either terminal serves as anode or cathode depending on transient polarity |
| Lead 1 | Current path input/output | Carries full surge current (up to 4.6 A peak) during clamping; requires ≥0.375" (9.5 mm) lead length for thermal dissipation per Fig. 5 |
| Lead 2 | Current path input/output | Completes symmetrical conduction path; identical thermal and electrical role to Lead 1 |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, low-drift VBR over temperature and lifetime, critical for long-term reliability in harsh environments |
| 1500 W peak pulse rating (10/1000 µs) | Supports IEC 61000-4-5 combination wave testing up to 4 kV open-circuit / 2 kA short-circuit without degradation |
| Sub-nanosecond response time | Clamps transients within 1 ns, protecting fast-switching MOSFET gates and precision analog front-ends before damage occurs |
| UL 94 V-0 epoxy molding | Provides flame-retardant mechanical encapsulation required for industrial control panels and automotive ECUs |
| AEC-Q101 qualified option (HE3 suffix) | Validates robustness for automotive applications including engine control, ADAS sensors, and infotainment power rails |

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 | DO-214AA package; lower PPPM = 600 W; VC = 356 V @ 2.2 A; smaller footprint but reduced surge capacity | Better suited for space-constrained PCBs with moderate surge requirements (IEC 61000-4-5 Level 2) | Select when board area is limited and peak surge energy does not exceed 600 W; verify thermal relief via copper pour. |
| 1.5KE220CAHE3_B | Identical electrical specs; AEC-Q101 qualified; HE3 suffix denotes RoHS + whisker-tested leads; "B" revision code | Required for automotive production programs needing PPAP documentation and extended temperature validation | Choose for OEM automotive designs where qualification traceability and long-term supply continuity are mandatory. |
Compared with 1.5KE220CA, SMBJ220CA trades surge capacity for compactness, while 1.5KE220CAHE3_B adds automotive-grade reliability without altering clamping behavior - enabling direct use in legacy industrial layouts or certified vehicle subsystems.

FAQ
What is the breakdown voltage tolerance for 1.5KE220CA?
The 1.5KE220CA has a specified breakdown voltage range of 209 V to 231 V at test current IT = 1 mA, representing ±5% tolerance around the nominal 220 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes from –55 °C to +175 °C.
Does 1.5KE220CA have polarity markings on the package?
No, 1.5KE220CA has no polarity markings because it is a bidirectional TVS diode. Both leads are functionally identical - the device clamps symmetrically for positive and negative transients. This eliminates orientation errors during manual or automated assembly and simplifies layout in AC-coupled or floating signal paths.
Can 1.5KE220CA be used in automotive applications?
Yes - the 1.5KE220CAHE3_B variant is AEC-Q101 qualified and approved for automotive use. While the standard 1.5KE220CA (E3 suffix) is commercial-grade, its 175 °C max junction temperature, UL 94 V-0 package, and robust surge rating make it suitable for non-safety-critical automotive subsystems like body control modules and HVAC actuators when validated per system-level requirements.
What is the clamping voltage of 1.5KE220CA at its rated peak pulse current?
The 1.5KE220CA clamps to a maximum of 328 V at its peak pulse current IPPM = 4.6 A (10/1000 µs waveform). This VC value defines the upper voltage limit imposed on protected circuitry during a full 1500 W transient event and must be compared against the absolute maximum ratings of downstream ICs and MOSFETs.
How does thermal derating affect 1.5KE220CA's power handling above 25 °C?
1.5KE220CA's power dissipation derates linearly above 25 °C ambient: from 6.5 W at TL = 75 °C (per Fig. 5), down to zero at TJ = 175 °C. For example, at 100 °C lead temperature, usable PD drops to ~4.3 W. Effective thermal design requires ≥0.375" (9.5 mm) lead length and adequate PCB copper area to maintain safe junction temperatures during repetitive surges.
