Product details
Overview
SMBJ160CA58HE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients up to 93.6 V at 6.4 A peak pulse current (10/1000 μs), with 160 V standoff voltage and 600 W peak pulse power rating. It protects sensitive ICs, MOSFETs, and sensor signal lines in industrial and telecom equipment against inductive switching surges and lightning-induced transients.
For engineers reviewing the SMBJ160CA58HE3/5B datasheet, SMBJ160CA58HE3/5B pinout, SMBJ160CA58HE3/5B application, or SMBJ160CA58HE3/5B equivalent, this AEC-Q101 qualified, RoHS-compliant TVS offers verified bidirectional clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for automotive-grade embedded protection and high-reliability board-level ESD/surge design.
Technical Context
This device operates as a voltage-clamped shunt protector: under transient overvoltage exceeding its 178–197 V breakdown range (VBR at 1 mA), it avalanches rapidly (<1 ns response) to limit voltage across protected circuitry to ≤93.6 V (VC at IPPM). Its bidirectional symmetry ensures identical clamping in both polarities, eliminating polarity concerns on AC-coupled or differential lines.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to +150 °C junction temperature. The glass-passivated junction and matte tin-plated leads meet J-STD-002/JESD22-B102 solderability standards, supporting automated SMT assembly without lead-free reflow degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 μA; defines safe working margin below clamping threshold. |
| VBR (min/max) | 178 V / 197 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on during transients; bidirectional symmetry applies. |
| VC @ IPPM | 93.6 V at 6.4 A - Clamped voltage under 600 W 10/1000 μs surge; directly limits stress on downstream components. |
| PPPM | 600 W - Peak pulse power handling capability per single transient event; validated per IEC 61000-4-5 waveform. |
| IPPM | 6.4 A - Peak surge current corresponding to 600 W at 93.6 V clamping; determines minimum trace width and PCB copper pad sizing. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial enclosures. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; can be stored indefinitely before reflow without baking. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode band absent (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal 1 | One side of bidirectional avalanche junction; electrically symmetric with Cathode; no polarity marking required. |
| Cathode | Terminal 2 | Other side of bidirectional avalanche junction; functionally identical to Anode in CA-suffix devices; terminals interchangeable in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - simplifies protection of AC, differential, or floating signal paths without polarity routing constraints. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - enables use in ADAS sensors, infotainment, and body control modules. |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 (4 kV) surges with margin - eliminates need for cascaded protection stages in industrial I/O interfaces. |
| Low clamping ratio (VC/VBR ≈ 0.53) | High energy absorption efficiency - reduces thermal stress during repeated transients and extends device lifetime in cyclic surge environments. |
| MSL Level 1 & RoHS-compliant | No moisture sensitivity concerns and full lead-free reflow compatibility - supports high-volume automated manufacturing without process derating. |
Applications
| Industrial Motor Drive I/O Protection | Automotive Sensor Signal Line Protection |

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-E3/5B | Same electrical specs and SMB package; lacks AEC-Q101 qualification and HE3 suffix - commercial grade only. | Not suitable for automotive applications requiring PPAP or AEC-Q101 validation; acceptable for industrial/commercial designs with lower reliability mandates. | Select when cost sensitivity outweighs automotive qualification needs and lifecycle assurance is not required. |
| SMAJ160CAHE3 | Lower 400 W PPPM, SMA (DO-214AC) package (smaller footprint, higher RθJA = 140 °C/W), same VWM/VBR. | Limited to lower-energy transients; thermal derating required above 75 °C ambient; unsuitable for high-duty-cycle surge environments. | Choose only if board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2 (1 kV). |
Compared with SMBJ160CA58HE3/5B, the E3/5B variant trades automotive qualification for lower cost, while SMAJ160CAHE3 sacrifices 33 % pulse power and thermal robustness for smaller size - making SMBJ160CA58HE3/5B the optimal choice for AEC-Q101–mandated, high-energy industrial and automotive protection.

FAQ
What is the breakdown voltage range of SMBJ160CA58HE3/5B?
The SMBJ160CA58HE3/5B has a guaranteed breakdown voltage (VBR) range of 178 V to 197 V at 1 mA test current, measured bidirectionally. This range ensures reliable and repeatable avalanche turn-on during overvoltage events, and is confirmed in Vishay's official SMBJ5.0A–SMBJ188A datasheet (Document Number: 88392, Rev. 09-Jan-2024). The SMBJ160CA58HE3/5B maintains this specification across its full operating temperature range.
Is SMBJ160CA58HE3/5B suitable for automotive applications?
Yes, SMBJ160CA58HE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and explicitly stated in Vishay's ordering information and thermal characteristics notes. It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and ESD qualification - making SMBJ160CA58HE3/5B appropriate for under-hood and chassis-mounted automotive systems such as engine control units and ADAS sensor interfaces.
What is the clamping voltage of SMBJ160CA58HE3/5B at its rated peak pulse current?
The SMBJ160CA58HE3/5B clamps to a maximum of 93.6 V at its rated peak pulse current (IPPM) of 6.4 A, using the standardized 10/1000 μs double-exponential surge waveform. This value is specified in the Electrical Characteristics table of the Vishay datasheet and reflects worst-case voltage seen by protected circuitry during a full 600 W transient event - a key parameter for verifying compatibility with downstream IC voltage tolerances.
Does SMBJ160CA58HE3/5B have polarity markings on the package?
No, SMBJ160CA58HE3/5B does not feature a cathode band or other polarity marking because it is a bidirectional TVS diode (denoted by the "CA" suffix). Both terminals are functionally identical, and the device provides symmetrical clamping behavior regardless of voltage polarity - eliminating orientation constraints during PCB layout and automated placement.
What is the moisture sensitivity level (MSL) rating for SMBJ160CA58HE3/5B?
SMBJ160CA58HE3/5B is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be stored indefinitely before reflow soldering without baking or dry-pack requirements. This is confirmed in the Mechanical Data section of the Vishay SMBJ5.0A–SMBJ188A datasheet and supports seamless integration into high-throughput SMT lines with standard lead-free reflow profiles.
