Product details
Overview
SMBJ160CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 160 V stand-off voltage (VWM), 259 V maximum clamping voltage (VC) at 2.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives and telecom power supplies.
For engineers reviewing the SMBJ160CA-M3/52 datasheet, SMBJ160CA-M3/52 pinout, SMBJ160CA-M3/52 application, or SMBJ160CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, 160 V reverse stand-off rating, low leakage (<1.0 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS compliance per Vishay's M3 suffix designation.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive transient stress.
The device delivers consistent clamping performance across -55 °C to +150 °C operating junction temperature, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W - optimized for PCB pad layouts matching the 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad recommendation per Vishay's test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse stand-off voltage before clamping initiates; defines safe operating margin for 120–150 V nominal DC bus lines. |
| VBR min / max | 178 V / 197 V at 1.0 mA - verified breakdown voltage range ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | 259 V at 2.3 A - clamping voltage under 10/1000 μs surge; limits downstream component stress to ≤259 V during transient suppression. |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage at rated stand-off voltage, minimizing standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - maximum junction temperature rating enabling use in enclosed industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" length and 0.155" width; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - both terminals are electrically symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical terminal behavior in either direction; enables placement without orientation check on PCB - simplifies layout and assembly for AC or differential lines. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment up to Level 4 (4 kV line-to-line, 2 kV line-to-ground). |
| Halogen-free & RoHS-compliant (M3) | Complies with IPC-1752A material declaration standards and EU RoHS Directive 2011/65/EU, including exemption 7a for lead in high-melting-temperature solder. |
| MSL Level 1 (260 °C peak) | Eliminates bake-out requirement prior to reflow; supports standard JEDEC J-STD-020 profile without moisture sensitivity risk. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients - critical for safeguarding 160–200 V-rated MOSFETs and gate drivers. |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of IGBT gate drive circuitry against switching-induced voltage spikes in 3-phase inverters. IC Role / Device Role / Timing Role: Bidirectional TVS placed across gate-source terminals to clamp negative and positive transients during Miller-effect coupling.

IC Role / Device Role / Timing Role: Bidirectional TVS connected between CANH and CANL to suppress common-mode transients without disrupting differential signaling. Use Value: Symmetrical clamping ensures equal response to positive/negative spikes, preserving signal integrity while meeting AEC-Q101 qualification via HM3 variant equivalents. |
Use Scenario: Overvoltage hardening of 4–20 mA current loop inputs in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across loop terminals to shunt induced lightning surges before reaching precision op-amp front-end. Use Value: 160 V VWM aligns with 24 V system derating margins; 259 V VC ensures downstream amplifier remains within absolute maximum ratings during 1 kV/μs transients. |
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-E3/52 | Same electrical specs and SMB package; RoHS-compliant but not halogen-free (E3 vs. M3). | Preferred for commercial-grade applications where halogen content is unrestricted; identical thermal and clamping performance. | Select E3 when halogen-free certification is not required and cost optimization is prioritized. |
| SMBJ160CAHM3_B/I | AEC-Q101 qualified, halogen-free, 13" tape-and-reel packaging (3200 pcs); same VWM, VC, and PPPM. | Required for automotive ECUs needing PPAP documentation and extended temperature validation (-40 °C to +125 °C ambient). | Choose HM3_B/I for automotive production programs requiring full AEC-Q101 traceability and volume packaging. |
Compared with SMBJ160CA-M3/52, the E3 variant offers identical protection performance at lower material cost for non-automotive use, while the HM3_B/I provides certified automotive reliability and higher-volume packaging - neither is pin-compatible in the sense of drop-in replacement without qualification, but all share identical SMB footprint and bidirectional functionality.

FAQ
What is the clamping voltage of SMBJ160CA-M3/52 under a 10/1000 μs surge?
The SMBJ160CA-M3/52 has a maximum clamping voltage (VC) of 259 V at 2.3 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components like 200 V MOSFETs remain within safe operating area.
Is SMBJ160CA-M3/52 suitable for automotive applications?
SMBJ160CA-M3/52 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ160CAHM3_B/I variant - identical electrical specs with full AEC-Q101 qualification, extended temperature validation, and PPAP-ready documentation. The M3/52 version may be used in non-safety-critical body electronics only after customer-level qualification.
What does the "CA" suffix indicate in SMBJ160CA-M3/52?
The "CA" suffix in SMBJ160CA-M3/52 denotes a bidirectional configuration - meaning the device clamps voltage transients equally in both polarities. Unlike unidirectional "A" variants, it has no cathode marking and functions identically regardless of terminal orientation, making it ideal for AC lines, differential buses (e.g., RS-485), or floating sensor interfaces where polarity cannot be guaranteed.
What is the maximum reverse leakage current for SMBJ160CA-M3/52 at its rated stand-off voltage?
At its 160 V reverse stand-off voltage (VWM), the SMBJ160CA-M3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, per Vishay's Electrical Characteristics table. This ultra-low leakage minimizes power loss in high-impedance monitoring circuits and ensures stable biasing in precision analog front-ends without loading sensitive nodes.
Does SMBJ160CA-M3/52 require special handling during PCB assembly?
No - SMBJ160CA-M3/52 is rated MSL Level 1 per J-STD-020, with a maximum reflow peak temperature of 260 °C. It can be processed using standard lead-free reflow profiles without baking or dry-pack requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable solder wetting and intermetallic formation in automated SMT lines.
