Product details
Overview
SMBJ58AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection of DC power rails and signal lines. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤93.6 V at 6.4 A, making it suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ58AHM3/H datasheet, SMBJ58AHM3/H pinout, SMBJ58AHM3/H application, or SMBJ58AHM3/H equivalent, this device is evaluated for ESD/surge immunity in 24–48 V DC systems, automotive body electronics, and telecom interface protection where low-leakage (<1 µA at 58 V), fast response (<1 ns), and AEC-Q101-qualified reliability are required.
Technical Context
This TVS operates as a unidirectional avalanche diode with cathode-banded polarity, optimized for clamping inductive switching spikes and lightning-induced surges on positive-rail circuits. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.104 %/°C), while the DO-214AA package supports automated SMT placement and meets MSL Level 1 reflow standards up to 260 °C.
It delivers 600 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = 150 °C. The 1.0 µA max reverse leakage at VWM minimizes standby power loss in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before significant conduction begins; sets upper limit for protected circuit's nominal DC rail. |
| VBR @ IT = 1 mA | 64.4–71.2 V - Breakdown voltage range defining onset of avalanche clamping; tight tolerance enables predictable protection threshold. |
| VC @ IPPM = 6.4 A | ≤93.6 V - Clamped voltage during 600 W surge event; determines maximum stress imposed on downstream components. |
| IPPM | 6.4 A - Peak pulse current corresponding to 600 W rating with 10/1000 µs waveform; defines surge handling capacity per event. |
| ID @ VWM | ≤1.0 µA - Reverse leakage current at standoff voltage; critical for low-power sensor and battery-critical applications. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with standard 0.2" × 0.2" copper pad layout. |
Pinout & Package
Package: SMB (DO-214AA), unidirectional configuration with cathode indicated by molded band. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop when transient exceeds VBR. |
| Cathode | High-side connection point | Connected to protected line (e.g., +24 V rail); band-marked terminal carries full surge current into ground via anode. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-event suppression of high-energy transients common in motor drives and relay coils without degradation. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JEDEC standards. |
| Halogen-free & RoHS-compliant (HM3) | Meets EU Directive 2011/65/EU and IPC-1752A material declarations; supports green manufacturing and end-of-life compliance. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), improving protection margin for sensitive CMOS inputs. |
| MSL Level 1 (260 °C peak) | Permits standard lead-free reflow without prebaking; eliminates moisture-related popcorning risk in high-volume SMT assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58AHE3/H | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification; same electrical specs and SMB package. | Approved for commercial/industrial use only; unsuitable for automotive production where halogen-free and AEC-Q101 are mandatory. | Select SMBJ58AHE3/H only when halogen content and automotive qualification are not required. |
| SMBJ58A-M3/52 | Same halogen-free and RoHS-compliant construction, but supplied in 7" tape-and-reel (750 pcs) vs. SMBJ58AHM3/H's H-coded 7" reel; identical electrical and thermal performance. | No functional difference; packaging variant affects inventory management and SMT feeder compatibility. | Choose SMBJ58A-M3/52 if standard M3 reel coding aligns with existing factory logistics systems. |
Compared with SMBJ58AHE3/H and SMBJ58A-M3/52, SMBJ58AHM3/H uniquely combines halogen-free materials, AEC-Q101 qualification, and HM3-specific reel coding-making it the only option qualified for Tier-1 automotive body control modules requiring full PPAP documentation and material traceability.

FAQ
What is the maximum clamping voltage of SMBJ58AHM3/H under a 600 W surge?
The SMBJ58AHM3/H clamps to a maximum of 93.6 V when subjected to its rated 600 W peak pulse power with a 10/1000 µs waveform. This value is measured at IPPM = 6.4 A and represents the highest voltage seen across the device during surge conduction-critical for verifying downstream component voltage margins. The SMBJ58AHM3/H maintains this clamping performance across its full operating temperature range.
Is SMBJ58AHM3/H qualified for automotive applications?
Yes, SMBJ58AHM3/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 88392 datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-making SMBJ58AHM3/H suitable for automotive body electronics, lighting, and infotainment power rails where reliability under thermal and mechanical stress is mandatory.
How does the HM3 suffix differ from HE3 or M3 in the SMBJ58A family?
The HM3 suffix on SMBJ58AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. In contrast, HE3 is RoHS-compliant but not halogen-free or AEC-Q101 qualified, while M3 is halogen-free and RoHS-compliant but lacks AEC-Q101 validation. Thus, only SMBJ58AHM3/H satisfies all three requirements-halogen-free materials, RoHS compliance, and automotive qualification-required for modern Tier-1 automotive programs.
What is the reverse leakage current specification for SMBJ58AHM3/H at its standoff voltage?
SMBJ58AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 58 V standoff voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage preserves battery life in always-on systems and avoids signal distortion in precision analog sensor interfaces. The SMBJ58AHM3/H maintains leakage below 5 µA up to 125 °C, supporting operation in high-temperature enclosures.
Can SMBJ58AHM3/H be used in bidirectional protection circuits?
No, SMBJ58AHM3/H is a unidirectional TVS diode, identified by its cathode band marking and specified breakdown behavior only in reverse bias. For bidirectional protection, Vishay offers the SMBJ58CA variant (with CA suffix), which provides symmetrical clamping in both polarities. Using SMBJ58AHM3/H in a bidirectional configuration would result in forward conduction and potential failure during negative transients.
