Product details

Overview

SMBJ60C-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features 60 V standoff voltage (V_WM), 66.7–73.7 V breakdown voltage (V_BR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤96.8 V at 6.2 A peak surge current - deployed in industrial sensor interfaces and telecom line protection.

For engineers reviewing the SMBJ60C-E3/5B datasheet, SMBJ60C-E3/5B pinout, SMBJ60C-E3/5B application, or SMBJ60C-E3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/V_WM ≈ 1.61), MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.

Technical Context

This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling robust suppression of ±600 W transient surges without polarity dependence. Its glass-passivated junction ensures stable leakage (<1.0 µA at V_WM) and fast response time (<1.0 ns), critical for safeguarding MOSFET gates and microcontroller I/O pins.

The SMBJ60C-E3/5B exhibits a thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting operation from –55 °C to +150 °C. It meets UL 497B recognition (QVGQ2) and is RoHS-compliant per base P/N-E3 designation, with no halogen content specified.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	60 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V DC systems.
V_BR (min/max)	66.7 V / 73.7 V at 1 mA - guaranteed avalanche onset range; ensures consistent turn-on across temperature and unit variation.
V_C @ I_PPM	≤96.8 V at 6.2 A - clamped voltage during 10/1000 µs surge; limits stress on downstream ICs to safe levels.
P_PPM	600 W - peak pulse power handling capacity; supports repetitive 0.01% duty cycle transients per JEDEC standards.
I_PPM	6.2 A - maximum non-repetitive surge current (10/1000 µs); determines minimum trace width and PCB pad sizing.
Junction Temp	–55 °C to +150 °C - extended thermal range enables use in automotive under-hood and industrial motor control environments.
Leakage @ V_WM	≤1.0 µA - ultra-low reverse leakage preserves signal integrity and battery life in always-on sensor circuits.

Pinout & Package

Package: SMB (DO-214AA), surface-mount, unmarked bidirectional configuration - no cathode band; terminals are matte tin-plated for J-STD-002 solderability.

Use Scenario: Input-stage surge protection for USB-C PD adapters and wireless charger controllers subjected to AC line transients. IC Role / Device Role / Timing Role: Placed across primary-side DC bus (e.g., post-bridge rectifier, pre-PFC stage) to clamp switching spikes. Use Value: 60 V V_WM aligns with 48–56 V DC bus designs; 96.8 V clamping prevents overvoltage failure of GaN FETs and controller ICs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ60CA-E3/5B	Identical electrical specs and package; CA suffix explicitly denotes bidirectional version per Vishay naming convention.	No functional difference - CA is the standardized bidirectional designation; C suffix may reflect legacy or internal marking variant.	Select SMBJ60CA-E3/5B for guaranteed documentation alignment and cross-reference clarity in BOMs.
SMCJ60C-E3/57T	Same V_WM/V_C, but in larger SMC (DO-214AB) package with 1500 W P_PPM and higher I_PPM (10.6 A).	Used where higher surge energy absorption is required (e.g., AC mains input stages), but requires larger PCB footprint and different thermal design.	Choose SMCJ60C-E3/57T only if system-level testing confirms need for >600 W surge handling; otherwise SMBJ60C-E3/5B offers optimal size/power balance.

Compared with SMBJ60CA-E3/5B, the SMBJ60C-E3/5B shares identical clamping performance and qualification but may differ in internal marking or revision tracking; versus SMCJ60C-E3/57T, it trades 2.5× lower surge rating for 40% smaller footprint and tighter layout integration in space-constrained signal-path protection.

FAQ

What is the standoff voltage rating of SMBJ60C-E3/5B?

The SMBJ60C-E3/5B has a maximum reverse standoff voltage (V_WM) of 60 V, meaning it remains in high-impedance state below this voltage and begins clamping above its breakdown range of 66.7–73.7 V. This rating makes SMBJ60C-E3/5B suitable for protecting 48 V DC systems where transient margins must exceed nominal rail voltage by ≥20%.

Is SMBJ60C-E3/5B bidirectional or unidirectional?

SMBJ60C-E3/5B is a bidirectional TVS diode, confirmed by the "C" suffix per Vishay's naming convention (where "C" = bidirectional, "A" = unidirectional). It provides symmetrical clamping for both positive and negative transients without polarity dependency - ideal for differential signal lines like RS-485 or CAN.

What package does SMBJ60C-E3/5B use, and is it RoHS-compliant?

SMBJ60C-E3/5B uses the SMB (DO-214AA) surface-mount package with matte tin-plated leads, compliant with J-STD-002 solderability standards. The "E3" suffix certifies it as RoHS-compliant and commercial-grade per Vishay's ordering nomenclature, with no halogen content declared.

What is the peak pulse power rating of SMBJ60C-E3/5B, and under what waveform?

SMBJ60C-E3/5B delivers 600 W peak pulse power under the standardized 10/1000 µs double-exponential surge waveform defined by ANSI/IEEE C62.35. This rating assumes mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per Vishay's test conditions - critical for achieving full rated performance in end applications.

Does SMBJ60C-E3/5B meet any safety certifications?

Yes, SMBJ60C-E3/5B carries Underwriters Laboratories (UL) recognition under file number E136766 and standard UL 497B for protectors, covering both unidirectional and bidirectional configurations. This certification validates its suitability for telecom and industrial signal-line protection where safety agency approval is mandatory.
