Product details
Overview
SMB10J11AHE3_A/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), 12.2–13.5 V breakdown voltage at 1 mA, and 18.2 V clamping voltage at 54.9 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMB10J11AHE3_A/H datasheet, SMB10J11AHE3_A/H pinout, SMB10J11AHE3_A/H application, or SMB10J11AHE3_A/H equivalent, this AEC-Q101 qualified TVS offers validated automotive-grade reliability, low incremental surge resistance, and fast response time for inductive load switching transients.
Technical Context
This unidirectional TVS operates with a standoff voltage of 11 V and clamps transients to ≤18.2 V at 54.9 A, enabling robust overvoltage protection without disrupting normal circuit operation. Its glass-passivated junction ensures stable leakage performance (<5 µA at VWM) and long-term reliability under repeated surge stress.
The device meets MSL level 1 per J-STD-020, supports lead-free reflow up to 260 °C peak, and delivers thermal resistance of 72 °C/W (junction-to-ambient) when mounted on 5.0 mm × 5.0 mm copper pads - critical for sustained surge handling in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.2 V / 13.5 V at 1 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 11 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA |
| VC @ IPPM | 18.2 V at 54.9 A - clamping voltage limiting downstream component stress during 10/1000 µs surge |
| PPPM | 1000 W - peak pulse power handling capability under standardized transient waveform |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine) |
| TJ max | 150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive electronic systems per stress test requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (during clamping) | Connected to protected line's low-side or ground return path; enables unidirectional clamping to ground |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line's high-side; avalanche conduction occurs when line voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tighter clamping (VC − VBR = 5.7–6.0 V), reducing voltage overshoot on sensitive loads |
| Glass passivated junction | Ensures stable VBR tolerance and <5 µA leakage at 11 V, critical for low-power sensor interfaces |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control, body electronics, and ADAS sensor protection |
| MSL Level 1 rating | Supports standard SMT reflow without moisture sensitivity concerns - no baking required prior to assembly |
| High power density | Delivers 1000 W surge capacity in SMB footprint (4.57 mm × 3.94 mm), minimizing board space vs. larger DO-214AB packages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A-E3/52 | Same SMB package, 11 V VWM, but lower PPPM = 600 W and higher VC = 18.2 V at 33 A | Not AEC-Q101 qualified; intended for commercial-grade consumer/industrial use only | Select when automotive qualification is unnecessary and cost optimization is prioritized over surge margin |
| SMCJ11AHE3_A/H | Larger SMC (DO-214AB) package, same VWM/VBR, but PPPM = 1500 W and VC = 18.2 V at 83.3 A | Higher thermal mass supports longer surge durations; requires larger PCB area | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and layout space permits larger footprint |
Compared with SMBJ11A-E3/52 and SMCJ11AHE3_A/H, SMB10J11AHE3_A/H uniquely balances AEC-Q101 compliance, 1000 W surge capacity, and SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability.

FAQ
What is the clamping voltage of SMB10J11AHE3_A/H at its rated peak pulse current?
The SMB10J11AHE3_A/H has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 54.9 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable overvoltage limiting for downstream components. The SMB10J11AHE3_A/H maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is SMB10J11AHE3_A/H qualified for automotive applications?
Yes, SMB10J11AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88422 (Revision 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction.
What is the standoff voltage and leakage current specification for SMB10J11AHE3_A/H?
The SMB10J11AHE3_A/H has a standoff voltage (VWM) of 11 V and a maximum reverse leakage current (ID) of 5.0 µA at that voltage, measured at 25 °C. This low-leakage characteristic prevents loading of high-impedance sensor or communication lines. The SMB10J11AHE3_A/H maintains leakage below 10 µA up to 125 °C, supporting stable operation in thermally demanding environments.
Does SMB10J11AHE3_A/H have a defined polarity marking, and how is it identified?
Yes, SMB10J11AHE3_A/H is unidirectional and features a visible cathode band on the SMB (DO-214AA) package body. Per Vishay mechanical drawings, the band is located at one end of the molded case and corresponds to the cathode terminal. During PCB layout, the cathode must be connected toward the protected line side, while the anode connects to ground or low-side reference - incorrect orientation disables clamping functionality.
What is the thermal resistance and recommended mounting for SMB10J11AHE3_A/H?
The SMB10J11AHE3_A/H 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, as specified in Vishay document 88422. To achieve rated 1000 W pulse power, this pad layout must be implemented; reduced copper area increases junction temperature and derates surge capability. The SMB10J11AHE3_A/H also exhibits RθJL = 20 °C/W to lead, supporting efficient heat transfer through solder joints.
