Product details
Overview
SMB10J36A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 1000 W peak pulse power (10/1000 µs), 17.2 A peak pulse current (IPPM), and clamps transients to ≤58.1 V. It is widely used in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J36A-M3/5B datasheet, SMB10J36A-M3/5B pinout, SMB10J36A-M3/5B application, or SMB10J36A-M3/5B equivalent, key selection criteria include clamping voltage under 58.1 V at 17.2 A, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and halogen-free RoHS-compliant M3 suffix packaging for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (40.0–44.2 V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its low incremental surge resistance ensures stable clamping performance across repetitive surges.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads per terminal, it achieves 72 °C/W junction-to-ambient thermal resistance and supports operating junction temperatures from –55 °C to +150 °C - meeting AEC-Q101 stress test requirements for automotive under-hood environments.
Key Specifications

|---|---|
| VWM | 36 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - guaranteed avalanche initiation range for reliable overvoltage triggering |
| VC @ IPPM | ≤58.1 V at 17.2 A - clamping voltage limiting downstream component stress during 10/1000 µs surge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-M3/5B | Same SMB package, identical VWM (36 V), VBR (40.0–44.2 V), VC (≤58.1 V), but rated for 600 W PPPM (vs. 1000 W) | Lower energy handling limits use to lower-tier surges (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 Pulse 5a | Select SMBJ36A-M3/5B only where peak surge energy is confirmed ≤600 W and automotive qualification is secondary |
| SMAJ36A-M3/5B | Smaller SMA (DO-214AC) package, same electrical specs except 600 W PPPM and higher RθJA (110 °C/W) | Reduced thermal margin and lower surge capacity restrict use to low-power consumer electronics, not automotive or industrial mains-connected equipment | Choose SMAJ36A-M3/5B only for space-constrained non-automotive designs where 600 W protection suffices and board layout cannot accommodate SMB footprint |
Compared with SMBJ36A-M3/5B and SMAJ36A-M3/5B, SMB10J36A-M3/5B delivers 67% higher peak pulse power (1000 W vs. 600 W) and lower thermal resistance (72 vs. ≥110 °C/W), making it the sole option among the three qualified for AEC-Q101 and capable of surviving full automotive load dump events without derating.

FAQ
What is the clamping voltage of SMB10J36A-M3/5B at its rated peak pulse current?
The SMB10J36A-M3/5B clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 17.2 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.2" × 0.2" copper pads), and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J36A-M3/5B maintains this clamping performance across its full operating temperature range.
Is SMB10J36A-M3/5B suitable for automotive applications?
Yes, SMB10J36A-M3/5B is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (M3 suffix), making it suitable for automotive powertrain, body electronics, and ADAS systems. Its 1000 W peak pulse power, 150 °C maximum junction temperature, and validated reliability testing meet stringent automotive environmental and lifetime requirements. The SMB10J36A-M3/5B is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "M3/5B" suffix mean in SMB10J36A-M3/5B?
The "M3" suffix indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, while "/5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This format ensures compatibility with high-speed SMT placement equipment and supports automated manufacturing for high-volume automotive and industrial production. The SMB10J36A-M3/5B ordering code guarantees traceable, standardized logistics handling.
How does SMB10J36A-M3/5B differ from bidirectional TVS diodes like SMB8J36CA-M3/5B?
SMB10J36A-M3/5B is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMB8J36CA-M3/5B is bidirectional with no polarity marking and symmetric clamping in both directions. Electrically, SMB10J36A-M3/5B offers 1000 W PPPM and 17.2 A IPPM, while SMB8J36CA-M3/5B provides 800 W PPPM and 13.8 A IPPM. The SMB10J36A-M3/5B is optimized for DC rail protection where reverse voltage is blocked; SMB8J36CA-M3/5B suits AC-coupled or floating signal lines.
What is the thermal resistance of SMB10J36A-M3/5B, and how does it affect PCB layout?
SMB10J36A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet Figure 6; reducing pad area increases RθJA and risks thermal runaway during repeated surges. To maintain reliability, designers must implement the specified copper land pattern and avoid excessive trace constrictions near SMB10J36A-M3/5B terminals.
