Product details
Overview
SMBJ60A-13-F from Diodes Incorporated is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with 60V reverse standoff voltage, 66.7V minimum breakdown voltage at 1mA, 96.8V maximum clamping voltage at 6.2A peak pulse current, and SMB package. It protects DC power rails and signal lines in industrial motor drives, telecom power supplies, and automotive body control modules against ESD and lightning-induced surges.
For engineers reviewing the SMBJ60A-13-F datasheet, SMBJ60A-13-F pinout, SMBJ60A-13-F application, or SMBJ60A-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 8.3ms half-sine waveform, thermal derating above +25°C, and RoHS-compliant matte tin lead finish for lead-free reflow compatibility.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below 60V VRWM, avalanches sharply at ≥66.7V VBR, and clamps transients to ≤96.8V VC while diverting up to 6.2A IPP. Its glass-passivated die ensures stable leakage (<5μA at VRWM) and repeatable breakdown behavior across temperature.
The device uses a single P-N junction structure optimized for fast response (<1ps typical), low capacitance (≤25pF at 0V), and robust surge handling per IEC 61000-4-5 Level 4 (4kV). Thermal performance is defined by 4.8W/°C derating above +25°C ambient and 150°C max junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains 8.3ms half-sine surge without failure; defines maximum energy absorption capability. |
| Reverse Standoff Voltage | 60V - Maximum continuous DC or RMS voltage before significant leakage; sets operating rail upper limit. |
| Breakdown Voltage | 66.7–76.7V @ 1mA - Guaranteed avalanche initiation range; determines clamping onset threshold. |
| Clamping Voltage | 96.8V @ 6.2A - Maximum voltage seen by protected circuit during rated surge; critical for IC overvoltage margin. |
| Peak Pulse Current | 6.2A - Maximum transient current diverted at specified clamping voltage; validates surge rating compliance. |
| Junction Temperature Range | −55°C to +150°C - Enables operation in harsh environments including engine compartments and industrial enclosures. |
| Leakage Current | ≤5μA @ 60V - Ensures minimal standby power loss and no interference with high-impedance sensing circuits. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with UL 94V-0 flammability rating, 0.1g weight, and matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode | Reference node | Typically tied to system ground or lower-potential rail; completes shunt path during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity without degradation in SMB footprint. |
| Glass-passivated die construction | Ensures stable electrical parameters over time and temperature; eliminates passivation-related drift in VBR. |
| Lead-free, RoHS-compliant finish | Matte tin plating enables compatibility with Pb-free reflow profiles (peak 260°C) and eliminates hazardous substances. |
| Low clamping ratio (VC/VRWM = 1.61) | Minimizes overvoltage stress on downstream ICs compared to higher-ratio TVS devices. |
| Uni-directional configuration | Provides asymmetric protection ideal for DC power rails where reverse polarity is not expected. |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of 48V DC bus against switching transients from IGBT gate drivers and relay coil flyback. IC Role / Device Role / Timing Role: Shunt clamping element placed between bus and chassis ground to limit voltage excursions during fault conditions. Use Value: Clamps 6.2A surges to ≤96.8V, maintaining bus integrity below 100V absolute maximum rating of associated MOSFETs and controllers. |
Use Scenario: Input-stage surge suppression on −48V telecom rectifier outputs exposed to lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground to clamp positive-going surges on negative supply rail. Use Value: Withstands 600W pulses while adding <25pF capacitance, avoiding signal integrity impact on -48V monitoring feedback paths. |
| Automotive Body Control Modules | Factory Automation I/O Cards |
Use Scenario: CAN bus power line protection in BCMs subjected to load dump and jump-start events per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12V auxiliary rail feeding microcontroller and CAN transceivers. Use Value: Limits transient voltage to 96.8V within 1ps response, preventing latch-up or permanent damage to 3.3V/5V logic powered from buck converters. |
Use Scenario: 24V digital input protection against field-wiring induced surges in PLC I/O modules. IC Role / Device Role / Timing Role: Front-end TVS on optocoupler input side to absorb inductive kickback from solenoid/valve coils. Use Value: Handles 6.2A peak current at 96.8V clamping, ensuring optocoupler LED forward voltage stays within safe operating range during surge events. |
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-13-F | Bi-directional version; symmetric clamping for AC or bidirectional signal lines. | Required where both positive and negative transients must be suppressed (e.g., RS-485 data lines). | Select only if bidirectional protection is needed; otherwise unidirectional SMBJ60A offers tighter clamping margin on DC rails. |
| SMCJ60A-13-F | Same voltage ratings but SMC package (higher 1500W PPK, larger footprint, 1.1g weight). | Used where higher surge energy (e.g., outdoor telecom cabinets) demands >600W rating. | Choose SMCJ60A only when 1500W rating is required; SMBJ60A provides optimal power density for space-constrained PCBs. |
Compared with SMBJ60CA-13-F, SMBJ60A-13-F delivers lower clamping voltage on DC systems due to unidirectional architecture; versus SMCJ60A-13-F, it trades peak power for 60% smaller board area and lighter weight-ideal for compact industrial controllers.

FAQ
What is the maximum clamping voltage of SMBJ60A-13-F at its rated peak pulse current?
The maximum clamping voltage is 96.8V at 6.2A peak pulse current (IPP) under 8.3ms half-sine waveform conditions. This value is guaranteed across temperature and represents the highest voltage imposed on the protected circuit during a full-rated surge event.
Is SMBJ60A-13-F suitable for protecting 3.3V logic circuits directly?
No-it is not suitable for direct protection of 3.3V logic because its 60V standoff voltage far exceeds the logic rail's maximum rating. It is designed for higher-voltage rails (e.g., 12V, 24V, 48V); use lower-voltage TVS like SMBJ3.3A for 3.3V interfaces.
How does the SMB package compare to SMA and SMC in terms of surge handling?
The SMB package supports 600W peak pulse power, positioned between SMA (400W) and SMC (1500W). Its 3.3–3.94mm height and 4.06–4.57mm width offer superior power density versus SMA while occupying less board area than SMC-ideal for mid-tier surge requirements.
Does SMBJ60A-13-F require heatsinking for continuous operation?
No external heatsink is required for transient suppression, as it operates in pulsed mode. However, steady-state power dissipation is limited to 5.0W at TL = +75°C; sustained DC leakage or frequent surges necessitate PCB copper pour per Diodes' recommended pad layout for thermal management.
