Product details
Overview
SMB10J5.0AHM3/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 - ideal for automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMB10J5.0AHM3/H datasheet, SMB10J5.0AHM3/H pinout, SMB10J5.0AHM3/H application, or SMB10J5.0AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low 72 °C/W junction-to-ambient thermal resistance, and halogen-free RoHS-compliant construction with matte tin leads.
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 glass-passivated silicon junction ensures stable leakage (<1000 µA at VWM = 5.0 V) and fast response time (<1 ns), enabling suppression of ESD, lightning-induced surges, and inductive switching spikes.
The SMB10J5.0AHM3/H uses a unidirectional configuration with cathode band marking, supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and is rated for -55 °C to +150 °C operation. Its MSL Level 1 rating and 260 °C lead-free reflow compatibility confirm suitability for automated SMT assembly in automotive-grade production.
Key Specifications

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 | Same SMB package, identical VBR/VC/PPPM, but commercial-grade (non-AEC-Q101), E3 suffix (RoHS, not halogen-free) | Lacks automotive qualification; suitable for consumer or industrial non-automotive designs | Select when AEC-Q101 is not required and halogen-free material is not mandated |
| SMAJ5.0AHE3/A | SMA (DO-214AC) package - smaller footprint, lower PPPM (400 W), higher RθJA (110 °C/W) | Lower surge capability and thermal performance; limited to lower-energy threats | Choose only for space-constrained boards where 400 W protection suffices and thermal margin allows |
Compared with SMBJ5.0AHE3/A and SMAJ5.0AHE3/A, the SMB10J5.0AHM3/H provides automotive-grade reliability, halogen-free compliance, and 2.5× higher surge power than the SMA variant - making it the preferred choice for mission-critical 5 V rail protection in harsh environments.

FAQ
What is the breakdown voltage tolerance for SMB10J5.0AHM3/H?
The SMB10J5.0AHM3/H has a specified breakdown voltage range of 6.40 V to 7.07 V at 10 mA test current (VBR min/max), measured per ANSI/IEEE C62.35. This ±10% tolerance ensures predictable turn-on behavior while accommodating process variation - critical for coordinating with 5 V system margins and avoiding false triggering.
Is SMB10J5.0AHM3/H compatible with lead-free reflow soldering?
Yes, SMB10J5.0AHM3/H is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, fully supporting lead-free soldering processes. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing - ensuring robust interconnect reliability in high-volume SMT lines.
How does SMB10J5.0AHM3/H differ from SMBJ5.0AHE3/A?
The SMB10J5.0AHM3/H differs from SMBJ5.0AHE3/A in three key ways: it carries the HM3 suffix (halogen-free + RoHS), is AEC-Q101 qualified, and belongs to the higher-power SMB10J family (1000 W vs. 600 W for SMBJ5.0A). These distinctions make SMB10J5.0AHM3/H suitable for automotive under-hood applications where environmental compliance and surge robustness are mandatory.
What is the maximum clamping voltage of SMB10J5.0AHM3/H under surge conditions?
The SMB10J5.0AHM3/H clamps to a maximum of 9.2 V at its peak pulse current of 108.7 A (10/1000 µs waveform). This value is guaranteed per datasheet specifications and reflects worst-case device behavior - enabling designers to verify that downstream 5 V ICs remain within absolute maximum ratings during transient events.
Can SMB10J5.0AHM3/H be used in bidirectional configurations?
No, SMB10J5.0AHM3/H is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA") and cathode band marking. For bidirectional protection at 5.0 V, Vishay offers SMB8J5.0CA variants - which feature symmetric breakdown and 800 W rating but require different layout and grounding considerations.
