Product details
Overview
SMBJ26A-13-F from Diodes Incorporated is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with 26V reverse standoff voltage, 28.9V minimum breakdown voltage, 42.1V maximum clamping voltage at 14.2A peak pulse current, and SMB package. It protects DC power rails and I/O lines in industrial motor drives against ESD, lightning-induced surges, and inductive switching transients.
For engineers reviewing the SMBJ26A-13-F datasheet, SMBJ26A-13-F pinout, SMBJ26A-13-F application, or SMBJ26A-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, 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 TVS operates as a clamping device: it remains high-impedance below VRWM (26V), avalanches sharply at VBR ≥28.9V, and limits transient voltage to ≤42.1V during 14.2A pulses. Its glass-passivated die ensures stable breakdown characteristics and low leakage (<5μA at 26V).
The SMB package enables compact PCB layout with 3.3–3.94mm height and 4.06–4.57mm width, supporting automated placement and reflow soldering per MIL-STD-202. Thermal resistance from junction to ambient is optimized for 5.0W steady-state dissipation at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 8.3ms surge without failure under defined test conditions |
| Reverse Standoff Voltage | 26V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 28.9V min - guaranteed avalanche onset threshold at 1.0mA test current |
| Clamping Voltage | 42.1V max at 14.2A - upper voltage limit imposed on protected circuit during surge |
| Peak Pulse Current | 14.2A - maximum non-repetitive surge current the device can safely divert |
| Leakage Current | ≤5μA at 26V - negligible standby power loss and minimal impact on high-impedance nodes |
| Operating Temp Range | −55°C to +150°C - suitable for under-hood automotive, industrial control, and outdoor equipment |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case rated UL 94V-0, 0.1g weight, matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode Reference / Ground Return | Unidirectional configuration: cathode connects to protected line; anode ties to system ground |
| Anode (Unmarked End) | Surge Return Path | Provides low-impedance path for transient current to ground during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 24V industrial buses |
| Glass Passivated Die | Ensures stable VBR over temperature and lifetime, with <5μA leakage at VRWM |
| Lead-Free & Halogen-Free | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity for standard SMT processing |
| SMB Package Footprint | Compatible with high-volume pick-and-place and reflow profiles; 5.00–5.59mm length minimizes board space |
Applications
| Industrial Motor Drive Control | PLC Digital I/O Protection |
|---|---|
Use Scenario: 24V DC control inputs on variable frequency drives exposed to inductive kickback from contactors and solenoids. IC Role / Device Role: Unidirectional TVS placed between input terminal and ground to clamp transients before reaching optocoupler or microcontroller GPIO. Use Value: Limits voltage to ≤42.1V during 14.2A surges, preserving signal integrity and preventing latch-up in downstream logic. | Use Scenario: 24V digital input modules in programmable logic controllers subject to field-wiring ESD and cable discharge events. IC Role / Device Role: Primary overvoltage clamp on each channel, mounted adjacent to connector entry point. Use Value: Maintains <5μA leakage at 24V operation, avoiding false triggering while delivering 600W surge handling per channel. |
| Factory Automation Sensors | DC Power Rail Protection |
Use Scenario: 2-wire 4–20mA loop-powered sensors in harsh factory environments with frequent ground potential shifts. IC Role / Device Role: Bidirectional protection not applicable; unidirectional SMBJ26A used across sensor supply and return to absorb common-mode transients. Use Value: Withstands −55°C to +150°C ambient, enabling direct mounting near motors or hydraulic valves without derating. | Use Scenario: 24V DC power distribution bus feeding multiple subsystems in embedded control cabinets. IC Role / Device Role: Bulk TVS at main power entry point to shunt lightning-induced surges before they propagate downstream. Use Value: 4.8W/°C thermal derating allows sustained operation up to +75°C lead temperature, matching typical enclosure thermal profiles. |

FAQ
What is the polarity configuration of SMBJ26A-13-F?
SMBJ26A-13-F is a unidirectional TVS diode with cathode band marking on one end. It conducts only when the marked (cathode) side is at higher potential than the unmarked (anode) side, making it suitable for DC rail protection where polarity is fixed. Bi-directional variants carry a "C" suffix (e.g., SMBJ26CA).
How does SMBJ26A-13-F compare to SMAJ26A in surge handling?
SMBJ26A-13-F delivers 600W peak pulse power in the larger SMB package, whereas SMAJ26A (SMA package) is rated for 400W. The SMB's lower thermal resistance supports higher surge energy absorption and better steady-state power dissipation (5.0W vs. 3.0W at TL = +75°C), making it preferred for high-reliability industrial deployments.
Can SMBJ26A-13-F be used in automotive applications?
Yes - SMBJ26A-13-F meets AEC-Q200 stress testing requirements for passive components and operates from −55°C to +150°C. It is commonly deployed in body control modules and infotainment power supplies for ISO 7637-2 pulse suppression, though automotive-grade variants may include additional qualification documentation.
What is the recommended PCB pad layout for SMBJ26A-13-F?
Diodes Incorporated specifies pad dimensions of C = 4.30mm, G = 1.80mm, X = 2.50mm, X1 = 6.80mm, and Y = 2.30mm (all in mm). These ensure full solder fillet formation, mechanical stability during thermal cycling, and compliance with IPC-7351B density level A for the SMB outline.
