Product details
Overview
SMBJ16A-13-F from Diodes Incorporated is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with 16.0V reverse standoff voltage, 17.8–20.5V breakdown range at 1.0mA test current, and 26.0V max clamping voltage at 23.1A peak pulse current. It features glass-passivated die construction, SMB package, and is rated for industrial power supply input protection and automotive ECU surge suppression.
For engineers reviewing the SMBJ16A-13-F datasheet, SMBJ16A-13-F pinout, SMBJ16A-13-F application, or SMBJ16A-13-F equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current capability under IEC 61000-4-5 8/20μs waveform, standoff voltage tolerance relative to DC rail, and SMB package thermal performance in high-density PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device, conducting only during negative transients relative to its anode-cathode polarity. Its glass-passivated junction ensures stable leakage (<5.0μA @ 16.0V) and repeatable breakdown behavior across temperature (-55°C to +150°C).
The device responds to transient surges with sub-nanosecond turn-on time, clamping voltages defined per IEC 61000-4-5 testing conditions (8/20μs waveform), and derates linearly above +25°C at 4.8W/°C for peak pulse power and 0.043W/°C for steady-state dissipation at lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 8/20μs surge events without failure per IEC 61000-4-5 Level 4 |
| Reverse Standoff Voltage | 16.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 17.8–20.5V @ 1.0mA - guaranteed conduction onset window for reliable overvoltage triggering |
| Max Clamping Voltage | 26.0V @ 23.1A - limits transient voltage seen by downstream circuitry during full-rated surge |
| Leakage Current | ≤5.0μA @ 16.0V - negligible standby power loss and no interference with low-power sensor rails |
| Package | SMB - standardized surface-mount footprint (5.59 × 4.06 mm) compatible with automated assembly and IPC-7351B land patterns |
Pinout & Package
Package: SMB (Surface-Mount Small Outline), molded plastic case per UL 94V-0, 0.1g mass, matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to system ground or low-impedance reference plane; carries full surge current during clamping |
| Cathode | Protected line connection | Connected to line being protected (e.g., 12V rail); polarity band identifies cathode on top surface |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables robust protection against IEC 61000-4-5 4kV (line-earth) and 2kV (line-line) surges without degradation |
| Glass Passivated Die | Ensures long-term parameter stability and resistance to humidity-induced leakage drift in harsh environments |
| RoHS & Halogen-Free | Meets EU Directive 2011/65/EU and green manufacturing requirements (<900ppm Br/Cl, <1000ppm Sb) |
| SMB Mechanical Standardization | Supports high-volume pick-and-place placement and reflow compatibility with industry-standard stencil profiles |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input stage of DIN-rail mounted PLC power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and chassis ground to shunt >100A surge currents within nanoseconds. Use Value: Limits transient voltage to ≤26.0V, protecting upstream rectifier diodes and downstream DC-DC controller ICs rated for 36V absolute maximum. |
Use Scenario: LIN bus interface and 12V auxiliary power lines in BCM modules subjected to ISO 7637-2 Pulse 1, 2a, and 5a. IC Role / Device Role / Timing Role: Primary overvoltage clamp on battery-supplied rails, operating in parallel with ESD diodes and filter capacitors. Use Value: Maintains <5.0μA leakage at 13.5V nominal battery, avoiding parasitic drain while clamping 100A pulses to safe levels for MCU I/O pins. |
| Telecom Remote Radio Unit (RRU) DC Feed | Smart Meter AC/DC Converter Input |
Use Scenario: -48V DC power feed line entering outdoor RRU enclosures, subject to lightning-induced surges on tower-mounted cables. IC Role / Device Role / Timing Role: First-stage surge suppression ahead of active OR-ing FETs and secondary TVS arrays. Use Value: Withstands 600W peak pulse without thermal runaway, enabling compact layout where space precludes larger DO-214AB packages. |
Use Scenario: Input rectified DC bus (≈320V) of smart meter switch-mode power supply, requiring coordinated clamping with MOVs. IC Role / Device Role / Timing Role: Fast-response secondary clamp complementing slower MOVs to handle fast-rising transients missed by bulk suppressors. Use Value: Sub-ns response time captures early voltage overshoot before MOVs fully activate, reducing stress on primary-side MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-13-F | Bi-directional configuration; symmetric clamping for AC or bidirectional signal lines | Required for RS-485 data lines or AC-coupled sensors where polarity reversal occurs | Select only when bidirectional surge protection is needed; adds ~0.5V higher clamping in each direction vs. unidirectional |
| SMCJ16A-13-F | Same electrical specs but in larger SMC package (7.11 × 6.22 mm); 1500W peak pulse rating | Used where higher surge energy handling is required and PCB area permits larger footprint | Choose for IEC 61000-4-5 Level 5 (6kV) compliance or repeated surge exposure; not drop-in due to different pad layout |
Compared with SMBJ16A-13-F, SMBJ16CA-13-F enables bidirectional clamping at the cost of slightly higher clamping voltage, while SMCJ16A-13-F trades PCB space for 2.5× higher surge energy capacity-neither is pin-compatible, and selection depends strictly on required clamping symmetry and surge energy class.

FAQ
What is the maximum operating temperature for SMBJ16A-13-F?
The SMBJ16A-13-F has a junction operating temperature range of –55°C to +150°C, verified per JEDEC JESD22-A103. Its thermal resistance from junction-to-lead is 23.3°C/W, allowing safe operation at full 600W pulse power only when leads are maintained near ambient temperature per datasheet Note 5.
Is SMBJ16A-13-F RoHS and halogen-free compliant?
Yes-SMBJ16A-13-F meets EU Directive 2011/65/EU (RoHS 2) with all applicable exemptions applied, and is certified halogen- and antimony-free ("Green") with bromine and chlorine <900ppm each (total Br+Cl <1500ppm) and antimony <1000ppm, as defined in Diodes Incorporated's green product specification.
How does SMBJ16A-13-F differ from SMBJ16CA-13-F?
SMBJ16A-13-F is unidirectional (cathode-banded), clamping only negative transients relative to its cathode; SMBJ16CA-13-F is bidirectional, clamping both polarities symmetrically. Their breakdown and clamping voltages differ slightly-SMBJ16CA-13-F has ±17.8–20.5V breakdown and ±26.0V clamping-making them non-interchangeable without circuit redesign.
Can SMBJ16A-13-F be used in parallel for higher surge current handling?
No-parallel connection is not recommended due to mismatched dynamic impedance causing current imbalance. The datasheet specifies single-device operation only; for higher current, select a higher-rated part like SMCJ16A-13-F or use external current-sharing resistors with careful thermal derating per application note DN005.
