Product details
Overview
1.5SMC220CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), 328 V maximum clamping voltage (VC) at 4.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC220CA-E3/57T datasheet, 1.5SMC220CA-E3/57T pinout, 1.5SMC220CA-E3/57T application, or 1.5SMC220CA-E3/57T equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device uses a planar silicon junction structure housed in an SMC (DO-214AB) package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), supporting reliable operation up to 150 °C junction temperature under defined PCB pad layout (8.0 mm × 8.0 mm copper).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before significant conduction; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 328 V at IPPM = 4.6 A (10/1000 μs) - Peak voltage seen by protected circuit; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Sustained surge energy handling capability per single transient; validated per REA-defined waveform. |
| ID (Reverse Leakage) | <1.0 μA at 185 V - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature rating; enables use in under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - Surface-mount outline with 7.75 mm × 6.22 mm footprint; compatible with automated placement and reflow. |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case meeting UL 94 V-0 flammability rating; terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking - both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical bidirectional avalanche behavior; either terminal serves as input/output for AC or floating lines. |
Key Features
| Feature | Design Value |
|---|---|

| 1500 W peak pulse power (10/1000 μs) | Withstands high-energy transients common in 24 V industrial control and automotive load-dump scenarios. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage overshoot during surge events, reducing stress on protected ICs and MOSFETs. |
| MSL Level 1 (260 °C peak) | Eliminates pre-bake requirements for standard SMT reflow, simplifying manufacturing and reducing cost. |
| AEC-Q101 qualification path | HE3/HM3 variants available - supports functional safety requirements in automotive ECUs and ADAS sensors. |

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), same VWM/VBR range, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Preferred for space-constrained consumer designs where surge energy is ≤600 W; less suitable for industrial load-dump. | Select when board area is limited and peak transient energy is confirmed ≤600 W; verify thermal derating on small pads. |
| 1.5KE220CA | Through-hole DO-201 package, identical electrical specs but higher mounting thermal resistance and manual assembly requirement | Used in legacy industrial power supplies and repair scenarios where SMT replacement isn't feasible. | Choose only for through-hole redesigns or prototyping; not recommended for new SMT production due to placement and reflow constraints. |
Compared with SMBJ220CA and 1.5KE220CA, the 1.5SMC220CA-E3/57T delivers 2.5× higher surge power in an automated SMT package with superior thermal coupling - making it optimal for high-reliability automotive and industrial applications demanding 1500 W clamping without layout compromise.

FAQ
What is the clamping voltage of the 1.5SMC220CA-E3/57T under a 10/1000 μs surge?
The 1.5SMC220CA-E3/57T has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 4.6 A with a 10/1000 μs waveform. This value is measured per REA-defined test conditions and reflects the actual voltage imposed on protected circuitry during worst-case transient events - critical for ensuring downstream components remain within safe operating limits.
Is the 1.5SMC220CA-E3/57T suitable for automotive applications?
Yes - the 1.5SMC220CA-E3/57T is RoHS-compliant and part of the AEC-Q101-qualified 1.5SMC family; while the -E3/57T variant itself is commercial grade, its base design supports AEC-Q101 qualification via HE3/HM3 suffixes. It meets key automotive requirements including MSL Level 1, 150 °C TJ max, and robust surge immunity - making it appropriate for non-safety-critical sensor and body-control modules.
How does the bidirectional configuration of the 1.5SMC220CA-E3/57T affect its usage?
The bidirectional configuration of the 1.5SMC220CA-E3/57T means it provides symmetrical clamping in both polarities - essential for protecting AC-coupled lines, differential interfaces (e.g., RS-485), or floating sensor outputs. Unlike unidirectional TVS diodes, it requires no orientation during placement and eliminates risk of reverse-polarity misapplication, simplifying layout and assembly for the 1.5SMC220CA-E3/57T.
What is the thermal resistance of the 1.5SMC220CA-E3/57T, and how does it impact PCB layout?
The 1.5SMC220CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes the recommended pad layout from the datasheet - undersized pads increase thermal impedance, risking premature thermal shutdown or degradation during repetitive surges. Proper copper area is essential to maintain 150 °C junction temperature compliance.
Does the 1.5SMC220CA-E3/57T have a specified junction capacitance?
No - the Vishay 1.5SMC220CA-E3/57T datasheet does not specify junction capacitance (CJ). Capacitance data is provided only for lower-voltage unidirectional variants (e.g., 1.5SMC6.8A) in Figure 4; bidirectional parts above 100 V, including the 1.5SMC220CA-E3/57T, omit CJ values due to measurement limitations at high VWM. For high-frequency signal line protection, consult Vishay's SMBJ or SMCJ series which publish CJ specs.
