Product details
Overview
SMB10J6.0AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 6.0 V stand-off voltage, and 10.3 V clamping voltage at 97.1 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and MOSFET gate drivers against inductive switching transients.
For engineers reviewing the SMB10J6.0AHM3/H datasheet, SMB10J6.0AHM3/H pinout, SMB10J6.0AHM3/H application, or SMB10J6.0AHM3/H equivalent, key selection criteria include clamping voltage vs. protected IC's absolute maximum rating, unidirectional polarity alignment with DC-biased circuits, AEC-Q101 qualification for automotive use, and SMB package compatibility with automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1000 MΩ at 6.0 V), but triggers into low-impedance conduction when transient voltage exceeds its 6.67–7.37 V breakdown range (tested at 10 mA). Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
Thermal design relies on its 20 °C/W junction-to-lead thermal resistance and 72 °C/W junction-to-ambient rating (on 5.0 mm × 5.0 mm copper pads); derating begins above 25 °C ambient per Figure 2, supporting continuous operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 10 µA; sets upper limit for DC bias in protected circuit. |
| VBR min/max | 6.67 V / 7.37 V - Breakdown occurs within this range at 10 mA test current; defines turn-on threshold tolerance. |
| VC @ IPPM | 10.3 V - Clamping voltage measured at 97.1 A peak pulse current; must be below protected device's absolute max rating. |
| PPPM | 1000 W - Peak pulse power handling capability with 10/1000 µs waveform; determines survivability of common lightning/surge events. |
| IFSM | 100 A - Non-repetitive forward surge current (8.3 ms half-sine); supports robustness against accidental polarity reversal surges. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with proper PCB thermal relief. |
| MSL Level | Level 1 (260 °C peak reflow) - Compatible with standard lead-free reflow profiles without moisture sensitivity concerns. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Primary-stage clamping device placed before TVS array or GDT, handling bulk energy before secondary protection engages. Use Value: Absorbs up to 1000 W of surge energy in 10/1000 µs waveform, reducing stress on downstream protection components and extending system MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same SMB package, identical VWM (6.0 V), VC = 10.3 V, but rated for 600 W PPPM (vs. 1000 W). | Lacks AEC-Q101 qualification; suitable for commercial-grade systems only. | Select when automotive qualification is unnecessary and cost optimization is prioritized over surge margin. |
| SMAJ6.0AHE3/A | SMA (DO-214AC) package, same electrical specs (VWM = 6.0 V, VC = 10.3 V), but lower PPPM = 400 W and higher RθJA = 90 °C/W. | Smaller footprint but reduced thermal mass and surge capacity; not recommended for high-reliability automotive use. | Choose only for space-constrained consumer designs where 400 W surge rating suffices and AEC-Q101 is not required. |
