Product details
Overview
SMBJ6V0CA from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for ESD and electrical fast transient (EFT) protection of sensitive ICs and systems. It features a 6.0V working stand-off voltage (VWM), 6.67–7.37V breakdown voltage (VBR) at 10mA test current, and clamps transients to ≤10.3V at 61A peak impulse current (IPP).
For engineers reviewing the SMBJ6V0CA datasheet, SMBJ6V0CA pinout, SMBJ6V0CA application, or SMBJ6V0CA equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, <1μA leakage above 10V, and DO-214AA mechanical compatibility with automated SMT assembly.
Technical Context
The SMBJ6V0CA implements a glass-passivated silicon junction optimized for low-capacitance, high-energy transient suppression in bidirectional signal and power lines. Its unidirectional counterpart (SMBJ6.0A) shares identical VWM and VBR ranges but lacks symmetrical conduction - the CA suffix explicitly denotes bipolar operation with matched forward/reverse characteristics.
Thermal performance is defined by RθJC = 10°C/W and RθJA = 55°C/W, enabling reliable operation up to TJ = +150°C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, confirming suitability for reflow-soldered industrial and automotive control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse/forward voltage before clamping begins; ensures no interference with 5V logic or USB signaling. |
| VBR @ IT=10mA | 6.67–7.37 V - Verified breakdown threshold under standardized DC test; guarantees consistent turn-on across production lots. |
| VC @ IPP=61A | ≤10.3 V - Clamped voltage during 10/1000µs surge; protects downstream 6V-rated components from overvoltage damage. |
| PPK | 600 W - Peak pulse power handling per single 10/1000µs transient; supports robust immunity against load dump and inductive switching events. |
| ID @ VWM | <1 µA - Ultra-low leakage at rated stand-off voltage; prevents battery drain in always-on circuits and preserves signal integrity. |
| Response Time | <1.0 ps - Junction-level reaction speed; enables effective suppression of ESD events (IEC 61000-4-2) before system damage occurs. |
| Package | DO-214AA (SMB) - Industry-standard surface-mount outline with 0.090g mass; compatible with JEDEC MS-013AC footprint and automated pick-and-place. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional symmetry means both terminals function identically).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | No polarity dependency - either terminal serves as input/output for surge current; eliminates orientation errors during placement. |
| Cathode Band (marking) | Manufacturing reference indicator | Present for traceability only; does not define functional polarity in CA-suffix devices. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery line transients), and Pulse 3a/3b (switching noise); suitable for automotive body electronics without external filtering. |
| Glass passivated junction | Enhances long-term reliability under thermal cycling and humidity exposure; reduces parameter drift over 10+ year service life in industrial controls. |
| Moisture Sensitivity Level 1 | Zero bake requirement prior to reflow; supports direct use from sealed tape-and-reel packaging in high-volume SMT lines. |
| RoHS & halogen-free | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; enables compliance in medical, consumer, and green energy applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA (ON Semiconductor) | Identical VWM (6.0V), VBR (6.67–7.37V), and VC (≤10.3V); same DO-214AA package; minor variation in IR spec (≤5µA vs. ≤1µA). | Same bidirectional functionality and ISO 7637-2 coverage; validated in automotive infotainment power supplies. | Preferred where ON Semi's AEC-Q200 qualification is required; slightly higher leakage acceptable in non-battery-critical designs. |

FAQ
What is the polarity configuration of SMBJ6V0CA?
SMBJ6V0CA is a bidirectional TVS diode - both terminals are functionally identical with symmetrical forward and reverse breakdown characteristics. The cathode band marking is present for manufacturing traceability only and does not indicate operational polarity. This allows flexible placement on PCBs without orientation constraints, unlike unidirectional variants such as SMBJ6.0A.
Does SMBJ6V0CA meet automotive EMC standards?
Yes, SMBJ6V0CA meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery line transients), and Pulse 3a/3b (switching noise), making it suitable for front-end protection in automotive body control modules, lighting systems, and infotainment power supplies. Its 600W peak pulse rating covers typical load-dump energy profiles.
What is the maximum clamping voltage of SMBJ6V0CA under surge conditions?
The maximum clamping voltage (VC) of SMBJ6V0CA is 10.3 V when subjected to a 61 A peak impulse current with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures downstream 6V-rated ICs remain within safe operating limits during transient events.
Can SMBJ6V0CA replace SMBJ6.0A in an existing design?
No - SMBJ6V0CA is bidirectional while SMBJ6.0A is unidirectional. Replacing SMBJ6.0A with SMBJ6V0CA may cause unintended conduction in DC-biased circuits. For unidirectional applications, use SMBJ6.0A or SMBJ6.0CA; for bidirectional signal lines (e.g., RS-485, USB D+/D−), SMBJ6V0CA is the correct choice.
What is the moisture sensitivity level (MSL) of SMBJ6V0CA?
SMBJ6V0CA has a Moisture Sensitivity Level (MSL) of 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions (<30°C / 60% RH) without baking prior to reflow soldering. This eliminates pre-bake steps in high-volume SMT assembly and supports immediate use from factory-sealed tape-and-reel packaging.
