Product details
Overview
SMB10J36A-E3/5B 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), 36 V stand-off voltage (VWM), and 58.1 V clamping voltage (VC) at 17.2 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain and industrial motor control systems.
For engineers reviewing the SMB10J36A-E3/5B datasheet, SMB10J36A-E3/5B pinout, SMB10J36A-E3/5B application, or SMB10J36A-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs transients, AEC-Q101 qualification status, RoHS-compliant E3 suffix, and thermal resistance (RθJA = 72 °C/W) for PCB layout validation.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and low incremental surge resistance, enabling fast response to ESD and inductive switching transients. Its breakdown voltage (VBR) is specified at 40.0–44.2 V with 1 mA test current, and it maintains stable clamping up to TJ = 150 °C.
The SMB10J36A-E3/5B uses a single-junction planar structure mounted on 0.2" × 0.2" copper pads, meeting MSL Level 1 per J-STD-020 and rated for 100 A non-repetitive forward surge (IFSM). Polarity is marked by cathode band; terminals are matte tin plated and solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 40.0 / 44.2 V - breakdown occurs within this range at 1 mA, defining turn-on threshold |
| VC @ IPPM | 58.1 V - clamps transients to ≤58.1 V at 17.2 A peak pulse current (10/1000 µs) |
| PPPM | 1000 W - peak pulse power handling capability defines surge energy absorption limit |
| RθJA | 72 °C/W - thermal resistance from junction to ambient determines required copper pad area for thermal management |
| TJ max | +150 °C - maximum junction temperature enables operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded UL 94 V-0 compound; cathode indicated by color band.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-E3/5B | Same SMB package, identical VWM (36 V) and VC (58.1 V), but rated for 600 W PPPM (vs. 1000 W) | Lower surge capacity suits consumer-grade or lower-risk industrial interfaces | Select SMBJ36A-E3/5B only if system-level surge testing confirms 600 W is sufficient; SMB10J36A-E3/5B provides 67% higher energy margin. |
| SMCJ36A-E3/5B | Larger SMC (DO-214AB) package, same electrical specs but higher PPPM (1500 W) and lower RθJA (40 °C/W) | Requires larger PCB footprint but delivers superior thermal performance in high-duty-cycle environments | Choose SMCJ36A-E3/5B when board space allows and sustained surge repetition rate exceeds SMB10J36A-E3/5B derating limits. |
Compared with SMBJ36A-E3/5B and SMCJ36A-E3/5B, SMB10J36A-E3/5B uniquely balances 1000 W surge capability with SMB footprint-enabling automotive-grade protection without SMC-level board area penalty or SMBJ-level power limitation.

FAQ
What is the clamping voltage of SMB10J36A-E3/5B at its rated peak pulse current?
The SMB10J36A-E3/5B has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 17.2 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with recommended 0.2" × 0.2" copper pads and defines the upper voltage limit imposed on protected circuits during surge events. The SMB10J36A-E3/5B maintains this clamping performance across its qualified operating temperature range.
Is SMB10J36A-E3/5B qualified for automotive applications?
Yes, SMB10J36A-E3/5B is AEC-Q101 qualified, confirming its reliability for automotive use cases including powertrain control, body electronics, and ADAS sensor interfaces. The "E3" suffix indicates RoHS-compliant commercial grade, and the device meets stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per AEC-Q101 Rev D. SMB10J36A-E3/5B is not an automotive-specific ordering code (which would use HE3/HM3), but its qualification applies to the base SMB10J36A construction.
What does the "-E3/5B" suffix mean in SMB10J36A-E3/5B?
The "-E3/5B" suffix in SMB10J36A-E3/5B specifies two attributes: "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads, and "5B" indicates packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This format aligns with Vishay's standardized ordering nomenclature and ensures compatibility with automated SMT placement equipment. The SMB10J36A-E3/5B is distinct from HE3-suffixed variants, which carry additional AEC-Q101 qualification documentation.
How does SMB10J36A-E3/5B differ from SMBJ36A-E3/5B?
SMB10J36A-E3/5B delivers 1000 W peak pulse power (PPPM), whereas SMBJ36A-E3/5B is rated for 600 W-making the SMB10J36A-E3/5B better suited for high-energy transients like load dump in automotive 36 V systems. Both share identical VWM (36 V), VC (58.1 V), and SMB package dimensions, but SMB10J36A-E3/5B achieves higher power via optimized chip geometry and thermal design. The SMB10J36A-E3/5B also features lower incremental surge resistance, improving clamping consistency under repeated stress.
What is the thermal resistance of SMB10J36A-E3/5B, and how does it affect PCB layout?
The SMB10J36A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB material and defines the required minimum copper area to maintain junction temperature below 150 °C during full-power surge events. Reducing pad size increases RθJA, risking thermal runaway; adding internal ground planes or thermal vias can improve heat dissipation. The SMB10J36A-E3/5B's RθJA enables compact layouts while sustaining AEC-Q101 reliability requirements.
