Product details
Overview
SMBJ60A-M3/52 from Vishay General Semiconductor is a unidirectional 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 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ60A-M3/52 datasheet, SMBJ60A-M3/52 pinout, SMBJ60A-M3/52 application, or SMBJ60A-M3/52 equivalent, key selection criteria include unidirectional polarity, 60 V operating voltage margin, 96.8 V clamping under surge, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS-compliant M3 suffix qualification for commercial-grade reliability.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, conducting only when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), enabling protection of sensitive downstream components against inductive switching spikes and ESD events.
The SMBJ60A-M3/52 delivers 600 W peak pulse power handling per 10/1000 µs waveform with 0.01% duty cycle, and supports 100 A non-repetitive forward surge current (IFSM) for short-duration overvoltage events. Its thermal design relies on PCB copper pad area (0.2" × 0.2") to achieve rated power dissipation and junction temperature limits up to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - Confirmed minimum/maximum voltage at which device enters avalanche breakdown; ensures predictable turn-on behavior |
| VC (Clamping Voltage) | 96.8 V at IPPM = 6.2 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized transient waveform; validates robustness against lightning or load-switch surges |
| IPPM (Peak Pulse Current) | 6.2 A - Maximum surge current the device can shunt while maintaining specified clamping; directly tied to PCB trace sizing and layout |
| TJ max. | +150 °C - Maximum allowable junction temperature; constrains thermal design and derating above 25 °C ambient |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires defined copper pad area (5.0 mm × 5.0 mm per terminal) to meet power ratings |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-E3/52 | Same electrical specs; RoHS-compliant but not halogen-free; uses standard SnPb-compatible plating | Preferred for legacy commercial designs where halogen content is unrestricted and cost sensitivity is higher | Select when halogen-free requirement is absent and procurement favors broader distributor stock availability |
| SMBJ60CA-M3/52 | Bidirectional variant; symmetrical VBR (66.7–73.7 V), same VC and PPPM; no polarity marking | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where voltage polarity reverses | Choose only if bidirectional clamping is needed; not a drop-in replacement due to polarity and circuit topology differences |

FAQ
What is the maximum clamping voltage of SMBJ60A-M3/52 under surge conditions?
The SMBJ60A-M3/52 has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during transient events. The SMBJ60A-M3/52 maintains this clamping performance across its full operating temperature range, ensuring consistent protection behavior in industrial environments.
Is SMBJ60A-M3/52 suitable for automotive applications?
The SMBJ60A-M3/52 is qualified to AEC-Q101 when ordered with HE3 or HM3 suffixes (e.g., SMBJ60A-HM3/52). As shipped, the SMBJ60A-M3/52 is commercial-grade and not AEC-Q101 certified. For automotive body control or infotainment systems, engineers must specify the HM3 variant to ensure qualification for temperature cycling, humidity, and mechanical shock testing. The SMBJ60A-M3/52 itself meets all electrical and thermal specs required for such use - only the qualification documentation differs.
How does the M3 suffix affect the SMBJ60A-M3/52 compared to E3?
The M3 suffix on SMBJ60A-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS-compliant but non-halogen-free material. Both share identical electrical parameters, package dimensions, and thermal characteristics. The SMBJ60A-M3/52 is selected when environmental compliance mandates halogen-free materials - critical for EU WEEE/ROHS II and certain OEM sustainability programs - without sacrificing surge performance.
What is the thermal resistance and how does it impact layout for SMBJ60A-M3/52?
The SMBJ60A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal planes. To sustain full 600 W pulse power, designers must allocate adequate copper area and consider thermal vias to inner layers. Exceeding ambient temperature derating curves (Fig. 2 in datasheet) without proper layout will reduce effective surge capability. The SMBJ60A-M3/52's thermal performance is fully validated under these conditions.
Can SMBJ60A-M3/52 be used in bidirectional signal protection?
No - SMBJ60A-M3/52 is a unidirectional TVS diode, intended for DC power rail or single-polarity signal protection. Its cathode band marking and asymmetric IV curve prevent reliable operation on AC or reversing-polarity lines. For bidirectional protection (e.g., RS-485, CAN, USB), the SMBJ60CA-M3/52 variant must be used. Substituting SMBJ60A-M3/52 in such applications risks failure during negative transients, as it lacks reverse conduction capability. Always verify polarity alignment before placing SMBJ60A-M3/52 in circuit.
