Product details
Overview
SMBJ60-E3/5B 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 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 96.8 V maximum clamping voltage (VC) at 6.2 A, and operates from –55 °C to +150 °C junction temperature - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ60-E3/5B datasheet, SMBJ60-E3/5B pinout, SMBJ60-E3/5B application, or SMBJ60-E3/5B equivalent, key selection criteria include unidirectional polarity, 60 V working voltage compatibility with 48 V DC systems, clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 100 °C/W), and RoHS-compliant commercial-grade packaging with matte tin leads.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle. The unidirectional configuration provides forward conduction path only during reverse overvoltage events.
Thermal design relies on PCB copper pad area (0.2" × 0.2") for derating above 25 °C ambient; RθJL = 20 °C/W supports localized heat transfer to leads. Polarity is marked by cathode band, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; matches 48 V nominal bus with 25% margin. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage limits downstream stress during 600 W transient; critical for 100 V-rated components. |
| PPPM | 600 W (10/1000 µs) - Peak surge handling capability for lightning-induced or inductive-switching transients in industrial environments. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands single-event high-current surges without bond-wire failure. |
| TJ max. | +150 °C - Enables operation in high-temperature enclosures or near power stages without thermal shutdown. |
| RθJA | 100 °C/W - Requires minimum 5.0 mm × 5.0 mm copper pads per terminal for full power rating at TA = 50 °C. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking.

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-M3/5B | Halogen-free, RoHS-compliant; identical electrical specs and SMB package. | No difference in protection performance; preferred where halogen-free compliance is mandated (e.g., EU public infrastructure projects). | Select SMBJ60A-M3/5B when halogen-free material declaration is required; otherwise SMBJ60-E3/5B offers standard commercial-grade compliance. |
| SMAJ60A-E3/61 | Lower peak pulse power (400 W), smaller SMA (DO-214AC) package, higher RθJA (140 °C/W). | Not suitable for 600 W surge environments; requires larger copper area or active cooling to match thermal performance. | Choose SMAJ60A-E3/61 only for space-constrained designs with reduced surge threat level (e.g., internal board-level coupling, not direct line entry). |
Compared with SMBJ60A-M3/5B, SMBJ60-E3/5B offers identical protection but with standard RoHS compliance; versus SMAJ60A-E3/61, it delivers 50% higher surge power handling and 29% lower thermal resistance - making it the preferred choice for primary-line protection in harsh industrial settings.

FAQ
What is the maximum clamping voltage of SMBJ60-E3/5B at its rated peak pulse current?
The SMBJ60-E3/5B has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 6.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see limited overvoltage stress during surge events. The SMBJ60-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ60-E3/5B suitable for automotive applications?
The SMBJ60-E3/5B is a commercial-grade part and not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ60HE3_B variant (with HE3 suffix), which is AEC-Q101 qualified and RoHS-compliant. The SMBJ60-E3/5B itself is intended for industrial, telecom, and consumer applications where automotive qualification is not required.
What is the standoff voltage (VWM) of SMBJ60-E3/5B and how does it relate to system voltage?
The standoff voltage (VWM) of SMBJ60-E3/5B is 60 V - the maximum DC or continuous reverse voltage the device can withstand without entering breakdown. It is selected to provide ≥20% margin above a 48 V nominal system bus, ensuring no leakage or conduction during normal operation while allowing rapid clamping during overvoltage events. This makes SMBJ60-E3/5B ideal for 48 V DC power distribution networks.
Does SMBJ60-E3/5B have polarity marking, and how is it identified?
Yes, SMBJ60-E3/5B is unidirectional and features a cathode band marking on the SMB (DO-214AA) package body. The banded end corresponds to the cathode terminal, which must be connected toward the protected line (e.g., 48 V input), while the anode connects to ground. This polarity is critical for correct clamping behavior and must be observed during PCB layout and assembly.
What is the thermal resistance and recommended PCB layout for SMBJ60-E3/5B to achieve full 600 W rating?
The SMBJ60-E3/5B 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 sustain full 600 W peak pulse power without exceeding TJ = 150 °C, designers must implement these minimum pad dimensions and ensure adequate copper area for heat spreading. Smaller pads will require derating per Figure 2 in the datasheet.
