Product details
Overview
SMB10J5.0AHE3_B/I 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), 6.4 V minimum breakdown voltage, and 9.2 V maximum clamping voltage at 108.7 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and microcontroller I/O pins against inductive switching transients.
For engineers reviewing the SMB10J5.0AHE3_B/I datasheet, SMB10J5.0AHE3_B/I pinout, SMB10J5.0AHE3_B/I application, or SMB10J5.0AHE3_B/I equivalent, this part delivers verified clamping performance under 1000 W surges, supports automated SMT placement, meets UL 94 V-0 flammability, and provides RoHS-compliant, AEC-Q101-qualified protection for automotive-grade electronics.
Technical Context
This TVS diode operates as a unidirectional clamping device with a 5.0 V stand-off voltage and 6.4–7.07 V breakdown range at 10 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD and lightning-induced transients on DC power rails and low-voltage signal paths.
The SMB10J5.0AHE3_B/I uses a glass-passivated pellet chip junction and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It is rated for -55 °C to +150 °C operating junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1000 W - sustains high-energy transients without failure in automotive and industrial environments |
| Stand-off Voltage (VWM) | 5.0 V - blocks normal operation voltage while remaining non-conductive below clamp threshold |
| Breakdown Voltage (VBR min/max) | 6.4 V / 7.07 V at 10 mA - defines reliable turn-on margin above VWM for predictable clamping onset |
| Maximum Clamping Voltage (VC) | 9.2 V at 108.7 A - limits protected circuit voltage during worst-case surge, preserving downstream ICs |
| Peak Pulse Current (IPPM) | 108.7 A - quantifies surge-handling capacity under standardized 10/1000 µs waveform |
| Junction Temperature Range | -55 °C to +150 °C - enables deployment in under-hood automotive and industrial control units |
| AEC-Q101 Qualified | Yes - validated for automotive electronic systems requiring reliability under thermal cycling and vibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB package, 1000 W rating, but commercial-grade (non-AEC-Q101); VBR min 6.4 V, VC = 9.2 V | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 not mandated | Select when cost sensitivity outweighs automotive reliability requirements and full qualification is unnecessary |
| 1.5SMC5.0A | Higher-power SMC package (1500 W), same 5.0 V VWM, but larger footprint (7.11 mm × 6.22 mm) and higher RθJA (40 °C/W) | Requires PCB area increase and thermal pad redesign; better for sustained surge duty cycles | Choose when system-level surge testing exceeds 1000 W or when board layout allows larger footprint for enhanced thermal margin |
Compared with SMBJ5.0A-E3/52, SMB10J5.0AHE3_B/I adds AEC-Q101 validation and tighter manufacturing controls for automotive use; versus 1.5SMC5.0A, it trades peak power for space-constrained mounting and lower thermal resistance to lead (RθJL = 20 °C/W).

FAQ
What is the clamping voltage of SMB10J5.0AHE3_B/I at its rated peak pulse current?
The SMB10J5.0AHE3_B/I has a maximum clamping voltage (VC) of 9.2 V at 108.7 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events. The SMB10J5.0AHE3_B/I achieves this with low incremental surge resistance, enabling consistent clamping performance across temperature and lifetime.
Is SMB10J5.0AHE3_B/I suitable for automotive applications?
Yes, SMB10J5.0AHE3_B/I is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix. It meets stringent requirements for thermal cycling, humidity resistance, and mechanical shock, and is deployed in body control modules, sensor units, and infotainment power rails. The SMB10J5.0AHE3_B/I also complies with MSL Level 1 and UL 94 V-0, supporting reflow assembly and safety certification in vehicle platforms.
What does the "_B/I" suffix mean in SMB10J5.0AHE3_B/I?
The "_B/I" suffix in SMB10J5.0AHE3_B/I indicates packaging configuration: "B" denotes the revision code (per Vishay's internal revision tracking), and "I" specifies 13-inch diameter plastic tape and reel packaging containing 3200 units. This format supports high-volume SMT assembly. The base "HE3" confirms RoHS-compliance and AEC-Q101 qualification, distinguishing SMB10J5.0AHE3_B/I from commercial variants like E3 or M3.
How does SMB10J5.0AHE3_B/I compare to bidirectional TVS diodes with the same VWM?
SMB10J5.0AHE3_B/I is unidirectional and optimized for DC rail or signal-line protection where polarity is fixed; bidirectional equivalents (e.g., SMB8J5.0CA) offer symmetrical clamping for AC-coupled or floating lines but deliver only 800 W peak power and higher clamping voltage (9.2 V at 87.0 A). The SMB10J5.0AHE3_B/I provides superior power handling and lower RθJL (20 °C/W), making it preferred for grounded 5 V systems with defined polarity.
What is the thermal resistance of SMB10J5.0AHE3_B/I, and why does it matter?
SMB10J5.0AHE3_B/I has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 72 °C/W when mounted on 5.0 mm × 5.0 mm copper pads. Low RθJL enables efficient heat transfer to PCB copper, critical for sustaining repeated surge events without thermal runaway. This parameter directly impacts long-term reliability in high-temperature environments such as automotive under-hood applications where the SMB10J5.0AHE3_B/I operates up to 150 °C junction temperature.
