Product details
Overview
SMBJ200CAQ-13-F from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMB package, rated for 600W peak pulse power, 200V reverse standoff voltage (VRWM), and 324V max clamping voltage (VC) at 1.9A IPP. It provides robust protection against ISO7637-2 pulses (Pulse 1: −150V; Pulse 2a: +112V; Pulse 3a: −220V; Pulse 3b: +150V) and ISO10605 ESD events (±30kV air/contact) in high-voltage vehicle subsystems.
For engineers reviewing the SMBJ200CAQ-13-F datasheet, SMBJ200CAQ-13-F pinout, SMBJ200CAQ-13-F application, or SMBJ200CAQ-13-F equivalent, this part is selected for AEC-Q101-compliant 12V/24V/48V automotive power rail surge suppression where precise clamping, low leakage (<0.5µA @ VRWM), and IATF 16949-manufactured traceability are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage VBR of 224–247V (min/max) at 1mA test current, enabling consistent overvoltage clamping during positive and negative transients. Its 324V clamping voltage at 1.9A peak pulse current ensures downstream circuitry remains below safe operating limits during ISO7637-2 Pulse 3b (+150V) and Pulse 1 (−150V) events.
Thermally rated for −55°C to +175°C junction operation and packaged in UL 94V-0 molded plastic SMB case, it supports high-reliability mounting on engine control units, battery management systems, and ADAS domain controllers where ambient temperatures exceed 125°C and moisture sensitivity is Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges without failure in automotive load-dump or inductive switching events |
| Reverse Standoff Voltage (VRWM) | 200V - defines maximum continuous DC or RMS operating voltage before significant leakage begins |
| Clamping Voltage (VC) | 324V @ IPP = 1.9A - limits transient voltage seen by protected ICs during ISO7637-2 Pulse 1 and Pulse 3a/b |
| Breakdown Voltage (VBR) | 224–247V @ IT = 1mA - ensures reliable turn-on margin above VRWM for stable clamping threshold |
| Leakage Current (IR) | <0.5µA @ VRWM - prevents parasitic drain in always-on 200V battery monitoring circuits |
| Operating Temperature | −55°C to +175°C - enables placement near high-heat sources like inverters or DC-DC converters |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing control |
Pinout & Package
Package: SMB surface-mount package (JEDEC DO-214AA), 3.30–3.94mm length × 5.00–5.59mm width × 2.00–2.50mm height, matte tin-plated terminals, 0.1g weight, RoHS- and halogen-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Absent) | Bi-directional terminal 1 | No polarity marking - symmetrical conduction allows bidirectional surge shunting without orientation dependency |
| Cathode (Cathode Band Absent) | Bi-directional terminal 2 | Identical to Anode - both terminals behave identically under positive or negative overvoltage conditions |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables protection against severe ISO7637-2 Pulse 1 (−150V) and Pulse 3a (−220V) without thermal runaway |
| Bi-directional architecture | Eliminates PCB layout constraints from polarity-sensitive placement in dual-rail or floating bus applications |
| AEC-Q101 qualification & PPAP support | Meets automotive change control requirements for Tier-1 BOM inclusion and production traceability |
| Low IR & tight VBR tolerance | <0.5µA leakage at 200V and ±10% VBR spread ensure predictable clamping onset in high-impedance sensing nodes |
| UL 94V-0 / MSL Level 1 | Supports reflow soldering without moisture-induced popcorning and meets flammability safety for under-hood modules |
Applications
| Engine Control Unit (ECU) Power Input | 48V Mild Hybrid Battery Management |
|---|---|
|
Use Scenario: Protects microcontroller power rails and CAN transceivers from load dump and alternator ripple in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Bi-directional TVS clamps both positive spikes (load dump up to +120V) and negative transients (inductive kickback down to −150V). Use Value: Maintains <324V clamping during ISO7637-2 Pulse 1, preventing damage to 3.3V/5V logic and ensuring CAN FD communication integrity. |
Use Scenario: Shields cell voltage monitors and isolation amplifiers in 48V BMS stacks exposed to regenerative braking surges and contactor bounce. IC Role / Device Role / Timing Role: Suppresses fast-rising transients (≤10ns rise time) on high-side sense lines tied to 48V nominal bus. Use Value: With 200V VRWM and 324V VC, it avoids false triggering during normal 48V operation while clamping >200V faults within 1ps response time. |
| ADAS Domain Controller Power Bus | Electric Power Steering (EPS) Motor Driver |
|
Use Scenario: Guards vision processor and radar SoC supply inputs against coupled noise from adjacent high-current actuators and switching regulators. IC Role / Device Role / Timing Role: Fast-response bi-directional clamp absorbs coupled transients from PWM-driven cooling fans and solenoid drivers sharing chassis ground. Use Value: Sub-1ns response and <0.5µA leakage preserve signal integrity on 1.8V/1.2V rails without adding offset or loading precision reference paths. |
Use Scenario: Installed across H-bridge half-bridges and gate driver supplies to absorb inductive energy during motor commutation and fault shutdown. IC Role / Device Role / Timing Role: Diverts 100A IFSM surge currents away from MOSFETs and bootstrap capacitors during short-circuit events. Use Value: 600W rating and 100A surge capability prevent latch-up in gate drivers and sustain safe operation during repeated EPS stall conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same electrical specs but non-AEC-Q101; no PPAP or IATF 16949 traceability | Acceptable for industrial or consumer designs lacking automotive qualification mandates | Select only if AEC-Q101 compliance and automotive change control are not required |
| SMCJ200CAQ-13-F | Same VRWM/VC but SMC package (higher 1500W PPK); larger footprint (7.11×6.22mm vs SMB 3.94×5.59mm) | Used where higher surge margin is needed and PCB space permits larger package | Choose when system-level testing requires >600W margin or legacy SMC footprint compatibility exists |
Compared with SMBJ200CA (non-automotive) and SMCJ200CAQ-13-F (higher-power SMC), SMBJ200CAQ-13-F uniquely delivers AEC-Q101 validation, PPAP readiness, and SMB-size integration for space-constrained automotive modules requiring certified surge immunity.

FAQ
What is the polarity configuration of SMBJ200CAQ-13-F?
SMBJ200CAQ-13-F is a bi-directional TVS diode with no cathode band marking. Both terminals are functionally identical, enabling symmetrical clamping of positive and negative transients without orientation-dependent installation. This eliminates PCB silkscreen polarity constraints and simplifies automated placement.
Does SMBJ200CAQ-13-F meet ISO7637-2 Pulse 3a requirements?
Yes - its 324V clamping voltage at 1.9A peak pulse current ensures compliance with ISO7637-2 Pulse 3a (−220V, 50Ω source impedance), limiting protected circuit voltage to well below typical 300V IC absolute maximum ratings. The 600W rating covers the full 10×1000µs waveform energy.
Can SMBJ200CAQ-13-F be used in 48V battery systems?
Yes - with 200V VRWM and 224–247V VBR, it provides ample margin above 48V nominal (including 58V float charge and 65V transients), while clamping at 324V ensures downstream 300V-rated MOSFETs and gate drivers remain within safe operating area during load dump or regenerative braking events.
What is the moisture sensitivity level (MSL) for SMBJ200CAQ-13-F?
SMBJ200CAQ-13-F has Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates pre-bake steps in standard SMT assembly and supports just-in-time manufacturing for automotive Tier-1 suppliers.
