Product details
Overview
SMBJ60-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 60 V standoff 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 - deployed in industrial motor drives, automotive ECUs, and telecom power supplies.
For engineers reviewing the SMBJ60-E3/52 datasheet, SMBJ60-E3/52 pinout, SMBJ60-E3/52 application, or SMBJ60-E3/52 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant commercial-grade qualification, and real-world implementation guidance for ESD and lightning-induced transient suppression.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging a glass-passivated silicon junction to deliver sub-nanosecond response time and low incremental surge resistance. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) support reliable operation up to 150 °C junction temperature when mounted on 5.0 mm × 5.0 mm copper pads.
The device complies with ANSI/IEEE C62.35 standards for transient suppressors and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow peak. Polarity is marked by a cathode band; it is not rated for bidirectional use and requires correct orientation in series with protected circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 66.7–73.7 V at IT = 1 mA - Guaranteed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 96.8 V at IPPM = 6.2 A (10/1000 µs) - Peak voltage seen by protected IC/MOSFET during worst-case surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustains single 10/1000 µs surges without failure; derates linearly above 25 °C ambient per Fig. 2. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - Withstands repetitive inrush or fault currents in power supply input stages. |
| TJmax | 150 °C - Enables deployment in under-hood automotive or high-temperature industrial enclosures without thermal shutdown. |
| Package | SMB (DO-214AA) - Low-profile, surface-mountable outline compatible with automated pick-and-place; 0.220" × 0.155" footprint. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated. Cathode indicated by a visible band on the body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or low-impedance return plane; completes clamping loop during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating in standard PCB layouts. |
| 96.8 V clamping at 6.2 A | Provides ≥25% voltage margin below 120 V-rated MOSFET gate oxide limits, preventing destructive overvoltage on power switches. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), critical for protecting high-speed logic interfaces. |
| MSL Level 1, 260 °C reflow compatible | Supports single-pass lead-free assembly without popcorn cracking or delamination; eliminates pre-bake requirements. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance mandates while maintaining full electrical performance across -55 °C to +150 °C operating range. |

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-M3/52 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package. | No functional difference; selected where halogen-free BOM compliance is mandated (e.g., EU medical devices). | Choose SMBJ60A-M3/52 when halogen-free material declaration is required; otherwise, SMBJ60-E3/52 offers same performance at standard cost. |
| SMAJ60A-E3/61 | Lower peak pulse power (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Not suitable for high-energy surges; limited to lower-duty-cycle or space-constrained consumer applications. | Select SMAJ60A-E3/61 only if board area is critical and surge energy remains below 400 W capability; verify thermal margin with layout simulation. |
Compared with SMBJ60A-M3/52, SMBJ60-E3/52 provides identical clamping and surge handling but lacks halogen-free certification; versus SMAJ60A-E3/61, it delivers 50% higher pulse power and superior thermal dissipation in the same mounting process - making it the preferred choice for industrial and automotive designs demanding robustness.

FAQ
What is the maximum clamping voltage of SMBJ60-E3/52 under a 10/1000 µs surge?
The SMBJ60-E3/52 has a maximum clamping voltage (VC) of 96.8 V when subjected to a 6.2 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the highest voltage the device allows across its terminals during standardized surge testing - directly defining the protection level for downstream components like MOSFETs or microcontrollers in the SMBJ60-E3/52-protected circuit.
Is SMBJ60-E3/52 suitable for bidirectional signal line protection?
No, SMBJ60-E3/52 is a unidirectional TVS diode and must be oriented with its cathode toward the protected line. For bidirectional protection (e.g., RS-485, USB D+/D−), a bidirectional variant such as SMBJ60CA is required. Using SMBJ60-E3/52 on AC-coupled or symmetrical signal paths risks forward conduction during negative transients, potentially damaging the SMBJ60-E3/52 or failing to clamp correctly.
Does SMBJ60-E3/52 meet AEC-Q101 automotive qualification?
No, SMBJ60-E3/52 is a commercial-grade part (E3 suffix). For AEC-Q101 qualification, the automotive-grade variant SMBJ60HE3_B/H must be specified. That version undergoes additional stress testing including temperature cycling, humidity bias, and accelerated life validation - whereas SMBJ60-E3/52 is rated for industrial and telecom use only, with no automotive qualification data published in its datasheet.
What is the thermal resistance of SMBJ60-E3/52, and how does it affect layout?
The SMBJ60-E3/52 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. To maintain safe operation at full 600 W pulse power, designers must ensure adequate copper area and avoid excessive trace length; reducing pad size increases RθJA, raising junction temperature and risking thermal runaway during repetitive surges - a key consideration in SMBJ60-E3/52 layout validation.
Can SMBJ60-E3/52 replace SMAJ60A-E3/61 in an existing design?
SMBJ60-E3/52 can replace SMAJ60A-E3/61 only if the PCB layout accommodates the larger SMB (DO-214AA) footprint and thermal requirements are re-evaluated. While both share 60 V VWM and similar VBR, the SMBJ60-E3/52 delivers 50% higher pulse power (600 W vs. 400 W) and lower thermal resistance (100 vs. 140 °C/W), but requires more board area. Swapping without layout review may cause solder joint stress or insufficient surge margin - verify mechanical fit and thermal performance before substituting SMBJ60-E3/52.
