Product details
Overview
SMBJ58AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR at 1 mA), 93.6 V max clamping voltage (VC) at 6.4 A peak pulse current, and 600 W peak pulse power (10/1000 µs waveform), used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ58AHE3_B/H datasheet, SMBJ58AHE3_B/H pinout, SMBJ58AHE3_B/H application, or SMBJ58AHE3_B/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature limit (TJ = 150 °C), and RoHS-compliant packaging details - all critical for automotive-grade surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device triggered by overvoltage events exceeding its reverse standoff rating. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, ensuring effective suppression of lightning-induced surges (IEC 61000-4-5) and inductive switching transients.
The SMBJ58AHE3_B/H is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports automated SMT placement, and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow profile. Its cathode band marking and matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 64.4 V / 71.2 V at IT = 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on under transient stress. |
| VC @ IPPM | 93.6 V at 6.4 A - Clamped voltage during 600 W 10/1000 µs surge; determines maximum stress imposed on protected downstream circuitry. |
| PPPM | 600 W - Peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 4 (4 kV) surge immunity designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58AHM3_B/H | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | No functional difference; selected when halogen-free compliance is mandated by OEM environmental policy. | Direct drop-in replacement where RoHS + halogen-free material declaration is required. |
| SMCJ58AHE3_A/H | Higher-power 1500 W version in larger SMC (DO-214AB) package; same VWM/VBR/VC ratings but higher IPPM (10.3 A). | Used where system-level surge testing exceeds 600 W (e.g., ISO 7637-2 Pulse 5a) or board layout allows larger footprint. | Choose when higher surge margin is needed and PCB space permits SMC package; not pin-compatible with SMBJ58AHE3_B/H. |
Compared with SMBJ58AHE3_B/H, the SMBJ58AHM3_B/H offers identical protection performance with halogen-free construction, while the SMCJ58AHE3_A/H provides 2.5× higher pulse power in a physically incompatible package - making the former a direct material alternative and the latter a system-level upgrade path.

FAQ
What is the maximum clamping voltage of SMBJ58AHE3_B/H under a 600 W surge?
The SMBJ58AHE3_B/H has a maximum clamping voltage (VC) of 93.6 V at 6.4 A peak pulse current, corresponding to the 600 W 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMBJ58AHE3_B/H maintains this clamping performance across its qualified operating temperature range.
Is SMBJ58AHE3_B/H qualified for automotive use?
Yes, SMBJ58AHE3_B/H is AEC-Q101 qualified, as confirmed in the Vishay ordering information table (page 3, footnote 1) and mechanical data section. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive modules. The "HE3" suffix explicitly denotes AEC-Q101 compliance in Vishay's naming convention.
What does the "B/H" suffix mean in SMBJ58AHE3_B/H?
The "B/H" suffix in SMBJ58AHE3_B/H indicates packaging configuration: "B" denotes tape-and-reel format per EIA-481, and "H" specifies a 7-inch diameter reel containing 750 units. This matches Vishay's preferred package code "H" in the Ordering Information table (page 3). The suffix does not affect electrical or thermal specifications - it solely identifies reel size and quantity.
How does SMBJ58AHE3_B/H differ from bidirectional variants like SMBJ58CA?
SMBJ58AHE3_B/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, SMBJ58CA is bidirectional, lacks polarity marking, and clamps symmetrically in both directions - suited for AC lines or differential signal pairs. Their VBR and VC values differ: SMBJ58CA has min/max VBR of 64.4–71.2 V in each direction but higher leakage and no IFSM rating.
What is the thermal resistance of SMBJ58AHE3_B/H, and how is it measured?
The SMBJ58AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay document 88392, page 3. This value assumes standard JEDEC test conditions and informs derating curves for power dissipation at elevated ambient temperatures - critical for thermal design in sealed enclosures.
