Product details
Overview
SMBJ6.0CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (IPPM), and 10.3 V maximum clamping voltage (VC) at IPPM, used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ6.0CAHM3_A/H datasheet, SMBJ6.0CAHM3_A/H pinout, SMBJ6.0CAHM3_A/H application, or SMBJ6.0CAHM3_A/H equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, AEC-Q101-qualified halogen-free construction, thermal resistance (RθJA = 100 °C/W), and direct replacement guidance for circuit-level ESD and surge protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR (6.4–7.07 V), VC (10.3 V), and IPPM (58.3 A) specifications in either direction. Its glass-passivated junction ensures stable avalanche performance under repetitive 10/1000 µs surges at 0.01% duty cycle.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads per terminal, it achieves 5.0 W steady-state power dissipation at TA = 50 °C and supports operating junction temperatures from –55 °C to +150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum reverse stand-off voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (min/max) | 6.4 V / 7.07 V - Breakdown voltage range at 10 mA test current; ensures reliable triggering across process variation |
| VC @ IPPM | 10.3 V - Clamped voltage during 58.3 A 10/1000 µs surge; determines protected circuit's maximum transient exposure |
| PPPM | 600 W - Peak pulse power handling capability; enables robust protection against IEC 61000-4-5 Level 4 surges |
| IPPM | 58.3 A - Peak surge current supported at VC; directly correlates to line impedance and surge source strength |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; requires minimum 5.0 mm × 5.0 mm copper pad area for rated power |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CAHE3_A/H | Same electrical specs, but RoHS-compliant (non-halogen-free) construction; no halogen-free certification | Approved for commercial and industrial use; not qualified for automotive under AEC-Q101 | Select when halogen-free requirement is not mandated and cost optimization is prioritized |
| SMAJ6.0CAHM3_A/H | Lower 400 W PPPM, 43.4 A IPPM, and 10.5 V VC; SMA (DO-214AC) package with smaller footprint (4.32 mm × 2.62 mm) | Suitable for space-constrained consumer PCBs; insufficient for 600 W surge requirements in industrial drives | Choose only if board area is critical and surge threat level is limited to IEC 61000-4-5 Level 2 (2 kV) |
Compared with SMBJ6.0CAHE3_A/H, the SMBJ6.0CAHM3_A/H adds halogen-free and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ6.0CAHM3_A/H, it delivers 50% higher surge power handling in a slightly larger SMB package-critical for automotive and industrial reliability.

FAQ
What is the clamping voltage of SMBJ6.0CAHM3_A/H at its rated peak pulse current?
The SMBJ6.0CAHM3_A/H has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated 58.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components remain within safe overvoltage limits during surge events. The SMBJ6.0CAHM3_A/H maintains this clamping performance bidirectionally due to its symmetrical junction structure.
Is SMBJ6.0CAHM3_A/H suitable for automotive applications?
Yes, SMBJ6.0CAHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix, confirming halogen-free, RoHS-compliant, and automotive-grade reliability. It is approved for use in engine control units, body electronics, and sensor modules where junction temperature must operate from –55 °C to +150 °C and withstand repetitive surge stress. The SMBJ6.0CAHM3_A/H meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility.
How does the bidirectional nature of SMBJ6.0CAHM3_A/H affect PCB layout?
The SMBJ6.0CAHM3_A/H has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies layout for AC-coupled lines, differential buses (e.g., RS-485), or ungrounded power rails where voltage polarity reversal is possible. Unlike unidirectional TVS diodes, the SMBJ6.0CAHM3_A/H avoids risk of incorrect installation and removes the need for silkscreen polarity indicators on the PCB.
What thermal derating applies to SMBJ6.0CAHM3_A/H above 25 °C ambient?
SMBJ6.0CAHM3_A/H follows the derating curve in Figure 2 of Vishay document 88392: its peak pulse power (PPPM) decreases linearly above TA = 25 °C, reaching ~50% of 600 W at TA = 100 °C. Steady-state power dissipation (PD = 5.0 W) is rated at TA = 50 °C and must be further reduced using RθJA = 100 °C/W. For reliable operation at 85 °C ambient, ensure junction temperature stays below +150 °C via adequate copper pour and airflow.
Can SMBJ6.0CAHM3_A/H replace SMBJ6.0A in a design?
No-SMBJ6.0A is unidirectional and requires correct cathode orientation; SMBJ6.0CAHM3_A/H is bidirectional with no polarity marking. Substituting SMBJ6.0CAHM3_A/H for SMBJ6.0A introduces no functional risk on AC or floating lines, but may reduce clamping margin on DC-biased rails where unidirectional blocking is intended. Always verify system-level surge path symmetry before replacement. The SMBJ6.0CAHM3_A/H retains identical VWM, VBR, and VC values as SMBJ6.0A, but with dual-direction conduction.
