Product details
Overview
SMBJ200AQ-13-F from Diodes Incorporated is a unidirectional 200V standoff, 600W peak pulse power automotive-grade transient voltage suppressor (TVS) diode in SMB package, with 324V max clamping voltage at 1.9A peak pulse current, AEC-Q101 qualified, and compliant with ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD standards for 12V/24V vehicle electrical systems.
For engineers reviewing the SMBJ200AQ-13-F datasheet, SMBJ200AQ-13-F pinout, SMBJ200AQ-13-F application, or SMBJ200AQ-13-F equivalent, this part supports high-reliability surge protection in automotive power line interfaces where precise clamping, low leakage (<0.5µA), and IATF 16949-manufactured traceability are required.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggered when reverse voltage exceeds 200V standoff (VRWM), with breakdown occurring between 224V–247V at 1mA test current. It delivers 600W non-repetitive pulse suppression per 10×1000µs waveform, derating linearly above +25°C ambient at 4.8W/°C.
Designed for automotive battery rail protection, it withstands ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), Pulse 3a (−220V), and Pulse 3b (+150V), while meeting ISO10605 30kV air/contact discharge requirements - all validated under −55°C to +175°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPK) | 600W - sustains single 10×1000µs transients without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage (VRWM) | 200V - blocks normal 24V system operation up to 200V before clamping activates |
| Max Clamping Voltage (VC) | 324V @ IPP = 1.9A - limits downstream voltage to safe level during ISO7637-2 Pulse 1/3a surges |
| Breakdown Voltage (VBR) | 224–247V @ IT = 1mA - ensures reliable turn-on margin above VRWM for stable clamping threshold |
| Reverse Leakage (IR) | <0.5µA @ VRWM - negligible standby current draw on 24V battery circuits over lifetime |
| Operating Temperature (TJ) | −55°C to +175°C - supports under-hood placement near engine control units and power distribution modules |
Pinout & Package
Package: SMB (Surface-Mount Body), molded plastic, UL 94V-0 rated, 0.1g weight, matte tin-plated terminals, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked band) | Surge current sink node | Connected to protected line; conducts transient energy to ground when reverse-biased beyond VRWM |
| Anode | Reference/ground return | Typically tied to chassis or system ground; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use across temperature, humidity, mechanical shock, and lifetime reliability stress tests |
| IATF 16949 manufacturing | Ensures consistent lot-to-lot performance, full traceability, and PPAP documentation support |
| ISO7637-2 & ISO10605 compliance | Guarantees interoperability with OEM surge immunity test plans without additional external filtering |
| Lead-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and automotive environmental mandates for end-of-life recyclability |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Interface |
|---|---|
Use Scenario: Protects 24V supply input of diesel/gasoline engine ECUs against load dump and alternator ripple-induced transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamps negative-going pulses (Pulse 1, −150V) and positive spikes (Pulse 2a, +112V) on main power rail. Use Value: Prevents latch-up or permanent damage to MCU power regulators and analog front-ends during cranking and alternator field collapse. | Use Scenario: Shields CAN_H/CAN_L lines in BCMs from ESD events and coupled transients from adjacent 12V lighting or motor drivers. IC Role / Device Role / Timing Role: Placed in parallel with CAN transceiver inputs to clamp fast-rising ESD (30kV contact/air) before signal integrity degrades. Use Value: Maintains CAN FD communication integrity during assembly handling and service operations without requiring extra RC filters. |
| ADAS Camera Power Rail | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Secures 12V input to rear-view or surround-view camera modules mounted in bumpers exposed to road-side ESD and ignition noise. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp absorbs ISO10605 discharges before they couple into image sensor bias rails. Use Value: Eliminates pixel corruption or frame drop during static discharge events without adding propagation delay to video path. | Use Scenario: Guards gate driver supply and feedback sensing lines in EPS motor controllers subjected to PWM switching noise and battery reversal. IC Role / Device Role / Timing Role: Absorbs repetitive low-energy transients from H-bridge commutation and protects op-amp current sense inputs. Use Value: Extends functional safety lifetime by preventing cumulative degradation of precision analog monitoring circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-Q | Same electrical specs; differs only in tape-and-reel packaging (no -13-F suffix), no date-code marking requirement | No functional difference; suitable for manual prototyping or small-batch builds without automated placement | Select when reel quantity flexibility or non-date-coded lots are acceptable |
| SMCJ200A-Q | Same VRWM/VC but in larger SMC package; higher IFSM (200A vs. 100A), 1500W PPK rating | Better suited for high-energy load dump in 48V mild-hybrid systems; requires larger PCB footprint | Choose when surge energy exceeds 600W or board layout allows SMC footprint |
Compared with SMBJ200AQ-13-F, SMBJ200A-Q offers identical protection performance with packaging flexibility, while SMCJ200A-Q trades compactness for higher surge capacity-making the SMBJ variant optimal for space-constrained 24V ADAS and body electronics.

FAQ
What is the polarity configuration of SMBJ200AQ-13-F?
SMBJ200AQ-13-F is a unidirectional TVS diode, with cathode indicated by a band on the SMB package. It conducts only during reverse overvoltage events and blocks forward current like a standard rectifier diode - confirmed by its "AQ" suffix (not "C") and absence of bi-directional marking codes (e.g., PV) in the datasheet table.
Does SMBJ200AQ-13-F meet AEC-Q101 Rev D requirements?
Yes - the datasheet explicitly states AEC-Q101 qualification, PPAP capability, and IATF 16949-certified manufacturing. Diodes Incorporated's official product definitions page confirms SMBJ-AQ devices comply with AEC-Q101 Rev D stress test conditions including HTGB, TCT, and UHAST, with full qualification reports available upon request.
Can SMBJ200AQ-13-F be used in 48V automotive systems?
No - its 200V VRWM and 324V VC are optimized for 24V nominal systems. In 48V architectures, load dump can exceed 60V, requiring higher VRWM devices (e.g., SMBJ350A) or multi-stage protection; using SMBJ200AQ-13-F risks premature clamping and thermal overstress during normal operation.
What is the maximum allowable PCB pad temperature during reflow soldering?
The SMB package supports lead-free reflow per JEDEC J-STD-020, with peak temperature ≤260°C for ≤30 seconds. The datasheet specifies moisture sensitivity level 1, meaning floor life is unlimited at ≤30°C/60% RH - no baking required prior to assembly, provided storage conditions are maintained.
