Product details
Overview
SMB10J5.0AHM3_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 on 5.0 V DC power rails and signal lines. It delivers 1000 W peak pulse power (10/1000 µs), clamps transients to ≤9.2 V at 108.7 A, and features 6.4–7.07 V breakdown voltage at 10 mA test current. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface and power rail protection.
For engineers reviewing the SMB10J5.0AHM3_A/H datasheet, SMB10J5.0AHM3_A/H pinout, SMB10J5.0AHM3_A/H application, or SMB10J5.0AHM3_A/H equivalent, key selection criteria include clamping voltage under 108.7 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and compatibility with 0.2" × 0.2" copper pad layout per JEDEC standard.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when reverse voltage exceeds its breakdown threshold (VBR = 6.4–7.07 V). Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Thermal performance is defined by RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), with maximum junction temperature rated at +150 °C. It meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1000 W - sustains single high-energy surges without failure on 5 V rails |
| Breakdown Voltage VBR | 6.4–7.07 V at 10 mA - defines precise conduction onset for 5 V system protection |
| Stand-off Voltage VWM | 5.0 V - ensures no leakage or conduction during normal 5 V DC operation |
| Clamping Voltage VC | ≤9.2 V at 108.7 A - limits downstream voltage stress to safe levels for 5 V ICs |
| Maximum Leakage ID | 1000 µA at 5.0 V - minimal standby power loss and signal integrity impact |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3_A/H | Same SMB package, identical VWM/VBR/VC, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy surge environments (e.g., consumer USB ports vs. automotive power rails) | Select when 600 W rating suffices and cost optimization is prioritized over automotive-grade surge margin |
| SMAJ5.0AHE3_A/H | SMA (DO-214AC) package, same electrical specs but lower 400 W PPPM and higher RθJA (90 °C/W) | Not suitable for high-power or thermally constrained automotive PCBs due to reduced power handling and thermal performance | Acceptable only for space-constrained non-automotive designs where 400 W surge capability is adequate |
Compared with SMBJ5.0AHE3_A/H and SMAJ5.0AHE3_A/H, SMB10J5.0AHM3_A/H provides 67 % higher peak pulse power and AEC-Q101 qualification-critical for automotive power rail protection where sustained 1000 W surge immunity and process reliability are mandatory.

FAQ
What is the polarity configuration of SMB10J5.0AHM3_A/H?
SMB10J5.0AHM3_A/H is a unidirectional TVS diode, with cathode marked by a visible band on the SMB package body. It conducts only when reverse voltage exceeds its breakdown threshold (6.4–7.07 V), making it suitable for DC rail protection where polarity is fixed. Bidirectional variants (e.g., SMB8J5.0CA) are separate part numbers.
Does SMB10J5.0AHM3_A/H meet automotive qualification standards?
Yes, SMB10J5.0AHM3_A/H carries the HM3 suffix, confirming halogen-free, RoHS-compliant construction and full AEC-Q101 qualification per the Vishay datasheet (Doc. #88422, Rev. 09-Jan-2024). This includes stress testing for temperature cycling, humidity, and mechanical shock required for automotive under-hood and ECU applications.
What is the maximum clamping voltage for SMB10J5.0AHM3_A/H under surge conditions?
The maximum clamping voltage (VC) for SMB10J5.0AHM3_A/H is 9.2 V at 108.7 A peak pulse current (10/1000 µs waveform), as specified in the unidirectional electrical characteristics table. This ensures protected 5 V logic circuits remain within safe operating voltage margins during transient events.
Can SMB10J5.0AHM3_A/H be used in place of SMBJ5.0AHE3_A/H?
No-SMB10J5.0AHM3_A/H is not a drop-in replacement for SMBJ5.0AHE3_A/H. While both are unidirectional 5 V TVS diodes in SMB packages, SMB10J5.0AHM3_A/H delivers 1000 W peak pulse power versus 600 W for SMBJ5.0AHE3_A/H. Substituting requires verification of surge energy requirements and thermal layout adequacy.
What PCB pad layout is recommended for SMB10J5.0AHM3_A/H?
Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 1000 W pulse power and thermal performance. The datasheet (Fig. 2, p. 4) confirms this layout enables proper heat dissipation and surge current handling-smaller pads will derate power capability significantly.
