Product details
Overview
SMCJ160CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power rating, 160 V standoff voltage (VWM), and clamping voltage of 259 V at 5.8 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive power systems, industrial motor controls, and telecom interfaces.
For engineers reviewing the SMCJ160CA-E3/57T datasheet, SMCJ160CA-E3/57T pinout, SMCJ160CA-E3/57T application, or SMCJ160CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix variants), UL 497B recognition, and compatibility with 10/1000 µs surge waveforms per ANSI/IEEE C62.35.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its reverse standoff voltage (VWM = 160 V) and limiting downstream voltage to ≤259 V under 10/1000 µs surges. Its bidirectional symmetry ensures identical clamping behavior across both polarities, eliminating polarity-dependent design constraints.
Constructed with glass-passivated junctions and rated for TJ = -55 °C to +150 °C, the SMCJ160CA-E3/57T delivers stable performance under thermal stress and meets MSL Level 1 (260 °C reflow). Its low incremental surge resistance and fast response time enable robust protection against inductive switching spikes and lightning-induced surges in DC power rails and data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown Voltage) | 178–197 V at IT = 1 mA - Confirmed breakdown threshold range defining clamping onset |
| VC (Clamping Voltage) | 259 V at IPPM = 5.8 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 µs transient waveform |
| ID (Max Reverse Leakage) | 1.0 µA at VWM - Minimal quiescent current draw ensuring negligible standby power loss |
| TJ max. | +150 °C - Maximum junction temperature enabling operation in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal requirement for rated power dissipation |
Pinout & Package
SMCJ160CA-E3/57T uses the SMC (DO-214AB) surface-mount package: 2-terminal, non-polarized bidirectional device with no cathode/anode marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; symmetric conduction path |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; no polarity marking required for bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR (178–197 V) and VC (259 V) in both directions enables single-device protection of AC-coupled or floating signal lines |
| UL 497B recognition | QVGQ2 listing (E136766) certifies suitability for telecom and industrial surge protection systems requiring safety agency approval |
| Low incremental surge resistance | Enables tighter clamping margin (VC − VBR ≈ 62–81 V), reducing stress on downstream MOSFETs and interface ICs |
| AEC-Q101 qualification path | E3 suffix indicates RoHS-compliant commercial grade; HE3 variant available for automotive-grade AEC-Q101 qualified versions |
| MSL Level 1 rating | Supports standard 260 °C lead-free reflow without preconditioning, simplifying manufacturing integration |

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-E3/52T | Lower PPPM (600 W), same VWM (160 V), SMB (DO-214AA) package (smaller footprint, higher thermal resistance) | Suitable for space-constrained consumer electronics where surge energy is limited to <600 W | Select when board area is critical and peak surge exposure is below 600 W; verify thermal derating for ambient >70 °C |
| SMCJ160A-E3/57T | Unidirectional version; identical VWM (160 V), VC (259 V), and PPPM (1500 W); includes cathode band marking | Required for DC-biased rails where reverse conduction must be blocked (e.g., positive-only supply lines) | Choose for unidirectional applications needing polarity-specific blocking; not interchangeable with SMCJ160CA-E3/57T without circuit review |
Compared with SMBJ160CA-E3/52T and SMCJ160A-E3/57T, the SMCJ160CA-E3/57T uniquely provides bidirectional 1500 W surge handling in the larger SMC package-enabling higher reliability in automotive and industrial settings where both polarity transients and thermal margin are critical.

FAQ
What is the clamping voltage of the SMCJ160CA-E3/57T under a 10/1000 µs surge?
The SMCJ160CA-E3/57T clamps to a maximum of 259 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 5.8 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during standardized surge events. The SMCJ160CA-E3/57T maintains this clamping performance bidirectionally, making it suitable for AC-coupled or floating nodes.
Is the SMCJ160CA-E3/57T RoHS-compliant and halogen-free?
Yes, the SMCJ160CA-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant and meets commercial-grade environmental requirements per Vishay's material categorization policy. It is not halogen-free; for halogen-free compliance, the "M3" suffix variant (e.g., SMCJ160CA-M3/57T) must be selected. Both E3 and M3 versions satisfy JESD 201 Class 2 whisker resistance testing.
Does the SMCJ160CA-E3/57T have AEC-Q101 qualification?
The SMCJ160CA-E3/57T itself is not AEC-Q101 qualified, as the "E3" suffix denotes commercial-grade construction. However, Vishay offers the functionally identical SMCJ160CAHE3_X variant (e.g., SMCJ160CAHE3_A) which adds AEC-Q101 qualification while retaining the same electrical specs and SMC package. Engineers designing for automotive applications should specify the HE3 suffix version to ensure qualification compliance.
What is the thermal resistance of the SMCJ160CA-E3/57T?
The SMCJ160CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 15 °C/W. These values assume proper PCB layout per Vishay's mounting pad recommendations and are essential for calculating safe operating temperature margins in high-ambient environments.
How does the SMCJ160CA-E3/57T differ from the unidirectional SMCJ160A-E3/57T?
The SMCJ160CA-E3/57T is bidirectional with symmetrical clamping in both polarities and no polarity marking, whereas the SMCJ160A-E3/57T is unidirectional, features a cathode band, and blocks reverse current above VWM. Both share identical VWM (160 V), VC (259 V), and PPPM (1500 W), but the SMCJ160CA-E3/57T is required for AC or floating signal paths, while the SMCJ160A-E3/57T suits DC rails with defined polarity.
