Product details
Overview
SMBJ58AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤93.6 V at 6.4 A peak surge current - used for protecting MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ58AHM3/I datasheet, SMBJ58AHM3/I pinout, SMBJ58AHM3/I application, or SMBJ58AHM3/I equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world clamping performance under standardized surge waveforms.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp with glass-passivated junction, optimized for fast response (<1 ps) to transient overvoltages induced by inductive switching or ESD events. Its low incremental surge resistance (Rdyn ≈ 14.6 Ω, derived from ΔVC/ΔIPPM) ensures minimal voltage overshoot during 600 W surges.
Thermally, it exhibits RθJA = 100 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 58 V - maximum continuous reverse voltage before leakage exceeds 1 µA; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 64.4–71.2 V at IT = 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during transients |
| VC (Clamping) | ≤93.6 V at IPPM = 6.4 A (10/1000 µs) - limits downstream voltage stress to protect 100 V-rated components |
| PPPM | 600 W - peak surge power handling capability; validated per IEC 61000-4-5 Level 4 (4 kV) surge immunity designs |
| IFSM | 100 A (8.3 ms half-sine) - supports robust inrush and fault-current tolerance in DC power rails |
| TJ max. | +150 °C - enables use in under-hood automotive modules and high-ambient industrial enclosures |
| Package | SMB (DO-214AA) - industry-standard 2-pin SMD outline; compatible with automated pick-and-place and reflow profiles up to 260 °C (MSL 1) |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded unidirectional configuration. Molding compound meets UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (non-banded end) | Current entry point during forward conduction | Connected to lower-potential side (e.g., GND or return path); enables unidirectional clamping from cathode to anode |
| Cathode (banded end) | Transient voltage reference node | Connected to protected line (e.g., 58 V rail); avalanche conduction begins here when VAK ≥ VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity up to 4 kV in 2 Ω/12 Ω source impedance configurations |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive powertrain and body electronics requiring zero defect rates and extended temperature cycling |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20 MSL level 1 reflow compatibility without brominated flame retardants |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage exposure to protected ICs - critical for 60–80 V logic and gate drivers |
| Fast response time (<1 ps) | Clamps ESD events (IEC 61000-4-2 ±8 kV contact) before sensitive circuitry sustains damage |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a, up to 120 V/400 ms). IC Role / Device Role / Timing Role: Unidirectional TVS placed between supply rail and ground to clamp overvoltage before reaching LDOs and microcontrollers. Use Value: Clamps to ≤93.6 V at 6.4 A, ensuring downstream 100 V-rated regulators remain within absolute maximum ratings during 300 ms load dump events. |
Use Scenario: 4–20 mA current loop transmitters in factory automation subject to field wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: TVS mounted across loop terminals to shunt transients before they reach precision op-amps and ADC front-ends. Use Value: Low leakage (<1 µA at 58 V) prevents loop current error; fast clamping preserves 12-bit measurement integrity during ±8 kV ESD events. |
| DC-DC Converter Input Protection | Motor Drive Gate Driver Protection |
Use Scenario: 48 V input stage of isolated buck converters in telecom rectifiers, subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Primary transient suppressor upstream of input filter capacitors and active FETs. Use Value: 600 W rating handles repetitive 10/1000 µs surges; thermal resistance (RθJA = 100 °C/W) allows sustained operation at 85 °C ambient without derating. |
Use Scenario: High-side N-channel MOSFET gate driver circuits in BLDC inverters, where Miller spikes and shoot-through cause localized overvoltage. IC Role / Device Role / Timing Role: TVS across gate-source to clamp transient spikes exceeding VGS abs max (±20 V). Use Value: VC ≤93.6 V ensures gate oxide remains intact even during 100 A motor stall currents inducing >60 V spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58AHE3/I | Same electrical specs; RoHS-compliant but not halogen-free; no AEC-Q101 qualification | Acceptable for commercial/industrial use where automotive reliability not required | Select when cost sensitivity outweighs halogen-free or automotive qualification needs |
| SMAJ58A-M3/5B | Lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Choose only for space-constrained consumer designs with <300 W surge requirements |
Compared with SMBJ58AHM3/I, SMBJ58AHE3/I lacks halogen-free content and automotive qualification but matches all electrical parameters, while SMAJ58A-M3/5B trades 33 % lower surge power and inferior thermal performance for smaller PCB area - making SMBJ58AHM3/I the optimal choice for high-reliability 600 W clamping in automotive and industrial systems.

FAQ
What is the maximum clamping voltage of SMBJ58AHM3/I at its rated peak pulse current?
The SMBJ58AHM3/I clamps to a maximum of 93.6 V when subjected to its rated peak pulse current of 6.4 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88392 and ensures protected downstream components remain within their absolute maximum voltage ratings during surge events.
Is SMBJ58AHM3/I suitable for automotive applications?
Yes, SMBJ58AHM3/I is AEC-Q101 qualified and carries the HM3 suffix, confirming halogen-free, RoHS-compliant construction and validation for automotive powertrain and body electronics. It meets temperature cycling, humidity bias, and mechanical shock requirements defined in AEC-Q101 Rev D.
What does the "HM3" suffix indicate in SMBJ58AHM3/I?
The "HM3" suffix in SMBJ58AHM3/I denotes halogen-free, RoHS-compliant packaging with AEC-Q101 qualification. It distinguishes this variant from E3 (RoHS only) and HE3 (AEC-Q101 but not halogen-free), confirming compliance with both environmental regulations and automotive reliability standards.
How does SMBJ58AHM3/I differ from SMBJ58AHE3/I?
SMBJ58AHM3/I and SMBJ58AHE3/I share identical electrical characteristics (VWM, VBR, VC, PPPM), but SMBJ58AHM3/I adds halogen-free molding compound and full AEC-Q101 qualification, whereas SMBJ58AHE3/I is RoHS-compliant and AEC-Q101 qualified but contains halogen-based flame retardants.
What is the thermal resistance junction-to-ambient for SMBJ58AHM3/I?
The typical thermal resistance junction-to-ambient (RθJA) for SMBJ58AHM3/I is 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88392. This value assumes standard FR-4 PCB layout and governs derating above 25 °C ambient.
