It features a 6.0 V stand-off voltage (VWM), 6.77–7.27 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤10.2 V at 58.9 A peak surge current - used in sensor interface protection and industrial I/O line safeguarding.
For engineers reviewing the SMBJ6.0CD-M3/H datasheet, SMBJ6.0CD-M3/H pinout, SMBJ6.0CD-M3/H application, or SMBJ6.0CD-M3/H equivalent, key selection criteria include bidirectional clamping capability, ±3.5 % VBR tolerance, low leakage (<500 μA at VWM), MSL Level 1 rating, and halogen-free RoHS-compliant construction per JESD 201 Class 2 whisker test.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling robust ESD and surge suppression without polarity sensitivity. Its low incremental surge resistance and fast response time ensure effective transient energy diversion before downstream ICs are damaged.
The SMBJ6.0CD-M3/H is rated for junction temperatures from –55 °C to +150 °C, with thermal resistance RθJA = 125 °C/W (on minimum pad layout) and RθJM = 20 °C/W, supporting reliable operation in thermally constrained industrial PCB layouts.
Key Specifications

FAQ
What does the "CD" suffix indicate in SMBJ6.0CD-M3/H?
The "CD" suffix denotes a bidirectional configuration, meaning SMBJ6.0CD-M3/H provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., SMBJ6.0D), it has no cathode band and is used where polarity of transient events cannot be assumed - such as AC signal lines, differential buses, or floating sensor outputs. This eliminates the need for orientation-aware placement during assembly.
Is SMBJ6.0CD-M3/H suitable for IEC 61000-4-5 surge testing?
Yes, SMBJ6.0CD-M3/H is rated for 600 W peak pulse power with a 10/1000 μs waveform, which aligns with IEC 61000-4-5 Level 4 (4 kV line-to-earth) when implemented with appropriate PCB layout - including minimum 5.0 mm × 5.0 mm copper pads and short, low-inductance traces. Its 10.2 V clamping voltage at 58.9 A ensures protected ICs remain within safe operating limits during standardized surge events.
How does the M3 suffix affect SMBJ6.0CD-M3/H's reliability?
The M3 suffix indicates SMBJ6.0CD-M3/H is halogen-free, RoHS-compliant, and qualified to JESD 201 Class 2 for whisker resistance - a critical requirement for industrial and automotive-adjacent applications where long-term solder joint integrity is essential. It also meets MSL Level 1 per J-STD-020, allowing exposure to standard SMT reflow profiles up to 260 °C without preconditioning.
What is the maximum steady-state power dissipation for SMBJ6.0CD-M3/H at 25 °C ambient?
SMBJ6.0CD-M3/H has a maximum steady-state power dissipation (PD) of 1.0 W at TA = 25 °C, derating linearly above that temperature per the published curve (Fig. 5). At TM = 50 °C (case temperature), its PD rises to 5.0 W - reflecting its ability to handle higher continuous power when mounted on a thermally optimized pad layout or heatsink, making it suitable for sustained overvoltage conditions in regulated power rails.
Can SMBJ6.0CD-M3/H replace unidirectional SMBJ6.0D in existing designs?
No - SMBJ6.0CD-M3/H is bidirectional and lacks a cathode band, whereas SMBJ6.0D is unidirectional with defined polarity. Substituting SMBJ6.0CD-M3/H for SMBJ6.0D may cause unintended conduction in DC-biased circuits or fail to clamp correctly in polarity-dependent configurations. Always verify circuit topology: use SMBJ6.0CD-M3/H only where true bidirectional protection is required and layout accommodates symmetric placement.
