Overview
1.5SMC160CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - used to safeguard automotive sensor signal lines, industrial I/O ports, and telecom interface circuits against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC160CA-E3/57T datasheet, 1.5SMC160CA-E3/57T pinout, 1.5SMC160CA-E3/57T application, or 1.5SMC160CA-E3/57T equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, RoHS-compliant commercial-grade construction, and direct alternatives for ESD/surge protection design-in across automotive, industrial, and communications systems.
Technical Context
The 1.5SMC160CA-E3/57T operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±179 V (VBR min) in both polarities without polarity marking. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, critical for protecting sensitive CMOS inputs and analog front-ends.
Rated for 1500 W peak pulse power (10/1000 μs), it sustains repetitive surges at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2, with thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads. Maximum junction temperature is 150 °C, and it meets MSL Level 1 per J-STD-020.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (160 V) and bidirectional configuration, but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 85 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-4 EFT); unsuitable for lightning-level threats requiring 1500 W rating. | Select when board space is constrained and surge threat level is limited to EFT or capacitive discharge only. |
| 1.5KE160CA | Same VWM and bidirectional function, but through-hole DO-201AE package; identical 1500 W rating but slower thermal recovery and larger PCB footprint. | Not suitable for high-density SMT layouts; requires wave soldering or hand assembly; less compatible with automated manufacturing. | Choose only for legacy through-hole designs or where mechanical robustness outweighs SMT process efficiency. |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CA-E3/57T uniquely balances 1500 W surge capability, SMC surface-mount compatibility, and commercial-grade RoHS compliance - making it optimal for new industrial and automotive electronics where space, manufacturability, and high-energy transient immunity are jointly critical.

FAQ
What is the clamping voltage of the 1.5SMC160CA-E3/57T at its rated peak pulse current?
The 1.5SMC160CA-E3/57T has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 6.8 A, measured under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The 1.5SMC160CA-E3/57T maintains this clamping performance due to its low incremental surge resistance and stable avalanche characteristics.
Is the 1.5SMC160CA-E3/57T suitable for automotive applications requiring AEC-Q101 qualification?
No - the 1.5SMC160CA-E3/57T carries the E3 suffix, indicating RoHS-compliant commercial grade only. For AEC-Q101 qualified versions, Vishay offers the 1.5SMC160CAHE3_A variant (with HE3 suffix), which undergoes additional stress testing for automotive under-hood use. The 1.5SMC160CA-E3/57T remains appropriate for non-safety-critical automotive subsystems such as infotainment or body electronics where qualification is not mandated.
How does the bidirectional configuration of the 1.5SMC160CA-E3/57T affect its placement on a PCB?
The 1.5SMC160CA-E3/57T has no polarity marking and functions identically in either orientation, simplifying layout and eliminating orientation errors during automated assembly. It must be placed across the protected nodes (e.g., between signal line and ground, or across differential pair) with minimal trace inductance - typically using short, wide traces and direct pad connection. The 1.5SMC160CA-E3/57T's symmetrical structure ensures equal clamping in both voltage polarities without requiring circuit redesign.
What is the thermal resistance and derating behavior of the 1.5SMC160CA-E3/57T?
The 1.5SMC160CA-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 JEDEC standards. Its peak pulse power must be derated linearly above 25 °C ambient temperature, dropping to ~75% at 75 °C and ~50% at 125 °C (per Fig. 2 in the datasheet). This derating ensures safe operation within the 150 °C maximum junction temperature limit. The 1.5SMC160CA-E3/57T's thermal performance supports sustained surge duty cycles in enclosed industrial enclosures.
Does the 1.5SMC160CA-E3/57T meet any international surge immunity standards out-of-the-box?
The 1.5SMC160CA-E3/57T itself is a component, not a system-level solution - but its 1500 W peak pulse rating (10/1000 μs) and 219 V clamping enable compliant designs for IEC 61000-4-5 Level 4 (4 kV line-to-ground, 2 kV line-to-line) when combined with proper PCB layout, grounding, and optional secondary protection. It also supports IEC 61000-4-2 ESD (±30 kV air, ±30 kV contact) when used with series impedance. The 1.5SMC160CA-E3/57T's parameters are validated per ANSI/IEEE C62.35 and UL 497B recognition.
