Product details
Overview
SMBJ60C-E3/52 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 standoff voltage (VWM), 66.7–73.7 V breakdown range at 1 mA test current, 96.8 V maximum clamping voltage 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 motor drives and telecom power supplies.
For engineers reviewing the SMBJ60C-E3/52 datasheet, SMBJ60C-E3/52 pinout, SMBJ60C-E3/52 application, or SMBJ60C-E3/52 equivalent, key selection criteria include unidirectional polarity, 60 V working voltage compatibility, 96.8 V clamping performance under 6.2 A surge, thermal resistance of 100 °C/W (junction-to-ambient), and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage behavior and fast response time (<1 ns), while the low incremental surge resistance minimizes voltage overshoot during transient events.
The SMBJ60C-E3/52 is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Vishay's Fig. 2 curve. It meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and is qualified to AEC-Q101 when ordered with HE3 suffix - though SMBJ60C-E3/52 itself is commercial-grade RoHS-compliant only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V DC bus protection. |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction under normal operation. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage limits downstream component stress during 10/1000 µs surge events. |
| PPPM | 600 W - Peak pulse power handling capacity with 0.01% duty cycle; sufficient for IEC 61000-4-5 Level 4 surges. |
| IPPM | 6.2 A - Peak pulse current capability with 10/1000 µs waveform; enables robust protection of 24–48 V systems. |
| TJ max | 150 °C - Maximum junction temperature allows operation in enclosed industrial enclosures with limited airflow. |
| RθJA | 100 °C/W - Thermal resistance indicates need for adequate PCB copper area (0.2" × 0.2") to sustain 5 W steady-state dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by band marking on one end; anode is unmarked end. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line (e.g., +VIN) to clamp overvoltage toward ground during transients. |
| Anode (unbanded end) | Reference/ground terminal | Typically tied to system ground or low-impedance return path; completes clamping circuit during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|

| Glass passivated junction | Ensures stable reverse leakage (<1 µA at 60 V) and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without moisture sensitivity concerns or baking requirements. |
| RoHS-compliant, matte tin plating | Guarantees solderability per J-STD-002 and whisker resistance per JESD 201 Class 2 for high-reliability production. |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and bootstrap circuits against inductive kickback from IGBT/MOSFET switching in 48 V BLDC motor controllers. IC Role / Device Role / Timing Role: Unidirectional TVS placed between high-side gate driver output and ground to clamp negative-going transients. Use Value: Prevents gate oxide damage by limiting voltage excursion to ≤96.8 V during 6.2 A surge events, preserving driver IC lifetime. |
Use Scenario: Input-stage surge suppression on 48 V DC distribution rails feeding PoE injectors and base station RF modules. IC Role / Device Role / Timing Role: Primary clamping device across input terminals to divert lightning-induced surges away from DC-DC regulators and PMICs. Use Value: Maintains rail integrity below 100 V during 600 W transient events, avoiding brownout or latch-up in downstream power management ICs. |
| Automotive Body Control Modules | Industrial Sensor Interfaces |
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and jump-start transients in 12 V subsystems. IC Role / Device Role / Timing Role: Secondary-level TVS on LIN data line and VCC supply, coordinated with primary 12 V rail TVS. Use Value: Limits clamped voltage to 96.8 V on 12 V lines, ensuring transceiver survival during ISO 7637-2 Pulse 5a events up to 100 V. |
Use Scenario: ESD and surge protection for analog outputs (4–20 mA) and digital I/O (RS-485) in factory-floor pressure/temperature sensors. IC Role / Device Role / Timing Role: Line-end TVS on signal pair or supply line to absorb contact discharge (IEC 61000-4-2) and burst noise (IEC 61000-4-4). Use Value: Clamps transients within 1 ns to prevent latch-up in precision op-amps and ADC front-ends, maintaining measurement accuracy. |
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 VWM (60 V), identical package and clamping (96.8 V), but unidirectional with cathode band - functionally identical to SMBJ60C-E3/52 per Vishay documentation. | No functional difference; both intended for unidirectional clamping; "C" and "A" suffixes denote same device in Vishay's naming convention for this family. | Select SMBJ60A-E3/52 if cross-referencing legacy designations; SMBJ60C-E3/52 is current preferred ordering code. |
| SMCJ60A | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs - requires PCB layout change and higher mounting pad area. | Suitable where higher surge margin is required (e.g., outdoor telecom cabinets), but not drop-in due to footprint and thermal mass differences. | Choose SMCJ60A only when 600 W is insufficient and board space allows larger SMC footprint and enhanced thermal coupling. |
Compared with SMBJ60A-E3/52, SMBJ60C-E3/52 offers identical electrical performance and packaging - confirming it as a direct revision update rather than functional variant; versus SMCJ60A, it trades surge headroom for compactness and lower thermal inertia, making it optimal for space-constrained 48 V industrial PCBs.

FAQ
What is the polarity configuration of SMBJ60C-E3/52?
SMBJ60C-E3/52 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the SMB package body, and it conducts only when reverse-biased beyond its breakdown voltage. This configuration makes SMBJ60C-E3/52 appropriate for DC line protection where polarity is fixed, unlike bidirectional variants such as SMBJ60CA.
Does SMBJ60C-E3/52 meet AEC-Q101 qualification?
No, SMBJ60C-E3/52 is a commercial-grade RoHS-compliant part. For AEC-Q101 qualification, Vishay specifies the HE3 suffix (e.g., SMBJ60AHE3), which includes additional stress testing and traceability. SMBJ60C-E3/52 shares identical electrical specs but lacks automotive qualification documentation and process controls.
What is the maximum clamping voltage for SMBJ60C-E3/52 under surge conditions?
The maximum clamping voltage (VC) for SMBJ60C-E3/52 is 96.8 V at 6.2 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can SMBJ60C-E3/52 be used in bidirectional signal line protection?
No - SMBJ60C-E3/52 is unidirectional and unsuitable for AC or bidirectional signal lines without external circuitry. For bidirectional protection, Vishay recommends SMBJ60CA (with 'CA' suffix), which provides symmetrical clamping in both directions and no polarity marking on the package.
What PCB pad layout is recommended for SMBJ60C-E3/52 to achieve rated thermal performance?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal to achieve the rated 100 °C/W junction-to-ambient thermal resistance and sustain 5.0 W power dissipation. Reducing pad size increases thermal resistance and reduces surge current handling capability.
