Product details
Overview
1.5SMC220A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 220 V standoff voltage (VWM), 209–231 V breakdown voltage (VBR) at 1 mA, and 1500 W peak pulse power (10/1000 µs). It clamps transients to ≤328 V at 4.6 A peak pulse current and is used for protecting MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the 1.5SMC220A-E3/57T datasheet, 1.5SMC220A-E3/57T pinout, 1.5SMC220A-E3/57T application, or 1.5SMC220A-E3/57T equivalent, key selection criteria include unidirectional polarity, 185 V maximum reverse leakage at VWM, 0.108 %/°C VBR temperature coefficient, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, conducting only when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable avalanche behavior, low incremental surge resistance, and fast response time (<1 ns) to ESD and lightning-induced surges.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power under JEDEC-standard 10/1000 µs waveform with 0.01 % duty cycle. Thermal resistance is 75 °C/W junction-to-ambient and 15 °C/W junction-to-leads, supporting operation from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse operating voltage before conduction begins; defines safe 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 - Peak voltage seen by protected circuit during 10/1000 µs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Sustained energy-handling capability under standardized surge waveform; enables robust protection against IEC 61000-4-5 Level 4 threats. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Minimal standby current; avoids parasitic loading on high-impedance signal or bias rails. |
| TJ max | +150 °C - Maximum junction temperature; supports reliable operation in under-hood automotive and industrial ambient environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with cathode band marking; compatible with automated pick-and-place and reflow processes. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground or low-side reference in unidirectional configuration | Provides return path during clamping; must be routed with low-inductance connection to minimize voltage overshoot. |
| Cathode | Current exit point in forward bias; marked with band; connected to protected line (e.g., power rail or signal trace) | Defines polarity-sensitive placement; incorrect orientation prevents clamping and risks catastrophic failure under reverse surge. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 surge immunity requirements up to 4 kV (line-earth) in properly designed layouts. |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage across temperature and lifetime; eliminates risk of junction degradation under repetitive surges. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin for sub-3.3 V logic interfaces. |
| AEC-Q101 qualification option (HE3/HM3) | Validates reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| MSL level 1 moisture sensitivity | Permits unlimited floor life and standard reflow without baking; reduces manufacturing overhead in high-volume SMT lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VWM (185 V) and VC (328 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select only where space constraints outweigh power-handling needs and thermal budget permits. |
| 1.5KE220A | Through-hole TO-204AA (DO-41); identical electrical specs but incompatible with SMT assembly; higher mounting inductance | Requires manual or wave soldering; not viable for automated production or compact PCBs | Choose only for legacy repair, prototyping, or non-SMT designs where board real estate is unconstrained. |

FAQ
What is the clamping voltage of the 1.5SMC220A-E3/57T under a 10/1000 µs surge?
The 1.5SMC220A-E3/57T clamps to a maximum of 328 V when subjected to its rated peak pulse current of 4.6 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads), and represents the upper voltage limit imposed on protected circuitry during transient events.
Is the 1.5SMC220A-E3/57T unidirectional or bidirectional?
The 1.5SMC220A-E3/57T is a unidirectional TVS diode, indicated by the "A" suffix and presence of a cathode band marking. It conducts only during reverse-biased overvoltage events and blocks forward current up to its rated IFSM of 200 A. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC220CA).
Does the 1.5SMC220A-E3/57T meet AEC-Q101 requirements?
The base 1.5SMC220A-E3/57T is RoHS-compliant and commercial-grade. AEC-Q101 qualified versions are available under ordering codes such as 1.5SMC220AHE3_A, which include additional stress testing and traceability for automotive applications. The "HE3" suffix denotes AEC-Q101 qualification, not the standard E3 variant.
What is the maximum operating temperature for the 1.5SMC220A-E3/57T?
The 1.5SMC220A-E3/57T has a maximum junction temperature (TJ max) of +150 °C and operates across a junction/storage temperature range of –65 °C to +150 °C. Its thermal resistance values (RθJA = 75 °C/W, RθJL = 15 °C/W) allow reliable operation in under-hood automotive and industrial environments when mounted per recommended pad layout.
How does the 1.5SMC220A-E3/57T differ from the SMBJ220A in practical design?
The 1.5SMC220A-E3/57T offers 1500 W peak pulse power in an SMC package, whereas the SMBJ220A provides only 600 W in the smaller SMB outline. This makes the 1.5SMC220A-E3/57T suitable for higher-energy threats like automotive load dump, while the SMBJ220A is limited to lighter-duty ESD and coupling transients in space-constrained designs.
