Product details
Overview
SMBJ200A-13-F from Diodes Incorporated is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 200V reverse standoff voltage (VRWM), 224–247V breakdown voltage (VBR), 324V maximum clamping voltage (VC) at 1.9A peak pulse current, and operates across –55°C to +150°C. Used in industrial power supplies to safeguard rectifier outputs against lightning-induced surges.
For engineers reviewing the SMBJ200A-13-F datasheet, SMBJ200A-13-F pinout, SMBJ200A-13-F application, or SMBJ200A-13-F equivalent, key selection criteria include clamping voltage margin relative to protected circuit's absolute maximum rating, peak pulse current capability under IEC 61000-4-5 waveform compliance, thermal derating at elevated ambient temperatures, and unidirectional polarity alignment with DC bus architecture.
Technical Context
This TVS diode employs glass-passivated silicon junction construction to achieve stable avalanche breakdown and low leakage (<1.0 µA at VRWM). Its unidirectional configuration provides asymmetric conduction-low forward voltage (~3.5 V at 35 A) during surge conduction while blocking reverse current until breakdown threshold is exceeded.
The SMB package enables high-power dissipation (600 W non-repetitive, 5.0 W steady-state at TL = +75°C) with controlled thermal resistance and JEDEC-compliant solderability. Pulse derating follows linear 4.8 W/°C reduction above +25°C ambient, validated per REA 10×1000 µs waveform testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10×1000 µs transients without failure per IEC 61000-4-5 Level 4. |
| Reverse Standoff Voltage | 200 V - Maximum continuous DC voltage before significant leakage; sets minimum operating margin for 240 VAC-derived rails. |
| Breakdown Voltage | 224–247 V - Measured at 1.0 mA IT; defines onset of avalanche clamping with ±5% tolerance. |
| Clamping Voltage | 324 V at 1.9 A IPP - Limits voltage seen by downstream components during surge; 62% over-voltage margin vs. VRWM. |
| Leakage Current | ≤1.0 µA at 200 V - Ensures negligible standby power loss and no false triggering in high-impedance bias networks. |
| Operating Temperature | –55°C to +150°C - Supports deployment in automotive engine compartments and industrial motor drives without derating. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with UL 94V-0 flammability rating, 0.1 g mass, matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode Reference / Surge Return Path | Identifies cathode terminal; connects to protected line side; anode ties to ground or lower-potential rail for unidirectional clamping. |
| Anode (Unmarked End) | Reference Node / Clamp Sink | Low-impedance path to system ground during transient; must be routed with minimal inductance to preserve clamping speed. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable VBR over temperature and lifetime; eliminates moisture-induced parameter drift in humid environments. |
| 600 W peak pulse rating | Meets IEC 61000-4-5 4 kV surge immunity requirement for industrial equipment without external series impedance. |
| RoHS-compliant & halogen-free | Complies with EU Directive 2011/65/EU and Diodes Inc.'s "Green" standard (<900 ppm Br/Cl, <1000 ppm Sb). |
| Moisture sensitivity Level 1 | Eliminates bake requirements prior to reflow; compatible with standard SMT assembly processes without floor-life constraints. |
Applications
| Industrial AC/DC Power Supplies | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of bridge rectifier outputs in 240 VAC-fed SMPS against lightning-induced ring waves. IC Role / Device Role / Timing Role: Unidirectional TVS placed between DC+ and chassis ground to clamp positive transients exceeding 200 V. Use Value: Limits voltage excursion to ≤324 V during 1.9 A surge, preventing MOSFET gate oxide rupture and bulk capacitor overvoltage failure. |
Use Scenario: Input protection for LIN bus transceivers exposed to load-dump events in vehicle door modules. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V supply rail upstream of regulator IC to absorb 120 V/50 ms pulses. Use Value: Clamps 200 V standoff line to 324 V within nanoseconds, preserving transceiver ESD robustness and enabling ISO 16750-2 compliance. |
| Telecom Remote Power Feeds | Renewable Energy Inverter DC Links |
Use Scenario: Surge suppression on 48 V PoE++ power feed lines in outdoor base station cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS on powered device (PD) input to shunt induced surges from nearby lightning strikes.

Use Scenario: Overvoltage clamp on photovoltaic string DC link feeding central inverters in solar farms. IC Role / Device Role / Timing Role: High-VRWM TVS installed across DC+ and DC− to protect IGBT gate drivers during grid fault recovery. Use Value: 200 V standoff accommodates 1000 V PV arrays; 324 V clamping prevents driver latch-up during fast-rising transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA-13-F | Bi-directional version; symmetrical clamping for AC-coupled or bidirectional signal lines. | Required where both positive and negative transients occur (e.g., RS-485 data lines), not suitable for DC bus protection. | Select only if protecting balanced differential signals or AC mains inputs; adds ~10% capacitance vs. unidirectional variant. |
| SMCJ200A-13-F | Same electrical specs but in larger SMC (DO-214AB) package; 1500 W peak power rating. | Used when higher surge energy handling is needed (e.g., primary-side AC input), requiring more PCB area. | Choose when system-level testing reveals >600 W surge exposure; footprint incompatible with SMB layout. |
Compared with SMBJ200CA-13-F and SMCJ200A-13-F, SMBJ200A-13-F delivers optimal space-constrained DC rail protection: its unidirectional polarity avoids unnecessary capacitance on power lines, while the SMB footprint supports dense industrial PCB layouts without sacrificing 600 W surge immunity.

FAQ
What is the maximum clamping voltage of SMBJ200A-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 324 V at 1.9 A peak pulse current (IPP), measured using the 10×1000 µs waveform per REA standards. This value ensures protected circuits remain below their absolute maximum voltage ratings during standardized surge events, and is guaranteed across the full operating temperature range.
Can SMBJ200A-13-F be used in bidirectional signal lines like RS-485?
No - SMBJ200A-13-F is unidirectional and conducts only when the cathode is positive relative to the anode. For bidirectional signal lines, the bi-directional SMBJ200CA-13-F must be used instead, as it clamps both polarities symmetrically and has identical VRWM and VC specifications.
How does the SMB package affect thermal performance compared to SMA or SMC?
The SMB package offers a thermal resistance of approximately 100°C/W junction-to-ambient (typical), enabling 5.0 W steady-state dissipation at TL = +75°C. It sits between SMA (higher RθJA) and SMC (lower RθJA, higher power), making it ideal for space-constrained designs needing 600 W pulse handling without oversized footprints.
Is SMBJ200A-13-F compliant with automotive AEC-Q200 stress testing?
No - SMBJ200A-13-F is qualified for commercial temperature range (–55°C to +150°C) and RoHS compliance, but it is not AEC-Q200 qualified. For automotive applications requiring qualification, Diodes' AEC-Q200-compliant P6SMBJ200A series should be selected, which undergoes additional temperature cycling and humidity testing.
