Product details
Overview
SMP6.0A-M3/85A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMP (DO-220AA) package, featuring 6.0 V stand-off voltage, 10.3 V clamping voltage at 38.8 A peak pulse current, and 400 W peak pulse power capability with 10/1000 μs waveform - designed for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMP6.0A-M3/85A datasheet, SMP6.0A-M3/85A pinout, SMP6.0A-M3/85A application, or SMP6.0A-M3/85A equivalent, key selection criteria include unidirectional polarity, 1.0 mm profile for space-constrained PCB layouts, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and verified clamping performance under 10/1000 μs surge conditions.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression, with breakdown voltage specified at 6.67–7.37 V (10 mA test current), clamping voltage of 10.3 V at 38.8 A, and low incremental surge resistance enabling effective energy diversion during ESD or load-switching events.
It is rated for -55 °C to +150 °C junction temperature, features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance - all within a compact DO-220AA outline measuring 3.61 mm × 2.18 mm × 1.0 mm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum reverse stand-off voltage before conduction begins; sets threshold for normal operation without leakage-induced interference |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - guaranteed avalanche breakdown range ensures consistent turn-on behavior across production lots |
| VC @ IPPM | 10.3 V at 38.8 A - clamping voltage limits downstream voltage stress during 10/1000 μs surges, protecting 5 V–6 V logic interfaces |
| PPPM | 400 W - peak pulse power rating defines maximum transient energy absorption capacity under standardized waveform |
| IFSM | 40 A - non-repetitive forward surge current rating supports robustness against single-event inrush or fault currents |
| TJ max | +150 °C - maximum junction temperature enables reliable operation in high-ambient industrial environments |
| RθJA | 250 °C/W - thermal resistance from junction to ambient informs derating requirements on standard PCB copper pads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMP6.0A-M3/84A | Identical electrical specs and package; differs only in tape-and-reel packaging (3000 pcs vs. 10000 pcs on 7" vs. 13" reel) | Same functional use; selected when smaller reels align with SMT line changeover frequency or pilot production volume | Choose SMP6.0A-M3/84A for prototyping or low-volume manufacturing with 7" reel feeders. |
| SMAJ6.0A | Same VWM (6.0 V) and VC (10.3 V), but larger SMA (DO-214AC) package (4.5 mm × 2.7 mm × 2.2 mm) and higher RθJA (300 °C/W) | Less suitable for ultra-thin or high-density layouts; requires more PCB area and exhibits greater thermal rise under repeated surges | Choose SMAJ6.0A only if legacy footprint compatibility or higher single-pulse margin (400 W same, but larger thermal mass) is prioritized over size. |
Compared with SMP6.0A-M3/84A, the SMP6.0A-M3/85A offers identical protection performance with optimized logistics for high-volume automated assembly; versus SMAJ6.0A, it delivers equal clamping efficacy in 45 % less board area and 20 % lower thermal resistance, making it preferable for modern compact designs.

FAQ
What is the clamping voltage of the SMP6.0A-M3/85A under a 10/1000 μs surge?
The SMP6.0A-M3/85A clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 38.8 A using the standardized 10/1000 μs waveform. This value is measured at the device terminals under defined test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads), and represents the upper voltage limit imposed on protected circuitry during transient events. The SMP6.0A-M3/85A maintains this clamping performance consistently across its qualified temperature range.
Is the SMP6.0A-M3/85A RoHS-compliant and halogen-free?
Yes, the SMP6.0A-M3/85A carries the M3 suffix, which certifies it as halogen-free, RoHS-compliant, and industrial-grade per Vishay's material categorization standards. Its molding compound meets UL 94 V-0 flammability rating, and its matte tin-plated leads satisfy solderability requirements per J-STD-002 and JESD 22-B102. The SMP6.0A-M3/85A also passes JESD 201 Class 2 whisker testing.
What is the maximum operating temperature for the SMP6.0A-M3/85A?
The SMP6.0A-M3/85A has a maximum junction temperature (TJ) rating of +150 °C and an operating junction and storage temperature range of -55 °C to +150 °C. This allows deployment in demanding environments such as industrial motor drives or under-hood automotive modules. Derating of peak pulse power applies above TA = 25 °C per Figure 2 in the official datasheet, and thermal design must account for RθJA = 250 °C/W on standard PCB pads.
Does the SMP6.0A-M3/85A have polarity marking, and how is it oriented on the PCB?
Yes, the SMP6.0A-M3/85A uses a color band to denote the cathode end, consistent with standard diode polarity convention. During PCB layout, the banded end must be connected to the reference ground or lowest potential node, while the anode connects to the line being protected. Incorrect orientation will prevent proper clamping action. The SMP6.0A-M3/85A is unidirectional and will not suppress positive transients on the cathode side.
What is the moisture sensitivity level (MSL) rating for the SMP6.0A-M3/85A?
The SMP6.0A-M3/85A is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can withstand reflow peak temperatures up to 260 °C without preconditioning or baking. This eliminates handling constraints typical of higher-MSL components and supports direct placement into high-throughput SMT lines. The SMP6.0A-M3/85A's MSL Level 1 status is confirmed in the "Mechanical Data" section of Vishay document 88481.
