Product details
Overview
SMCJ58CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with a 10/1000 μs waveform. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, and clamps to ≤93.6 V at 16.0 A peak pulse current. It protects signal lines and power rails in automotive sensor interfaces and industrial control I/O.
For engineers reviewing the SMCJ58CAHM3_A/H datasheet, SMCJ58CAHM3_A/H pinout, SMCJ58CAHM3_A/H application, or SMCJ58CAHM3_A/H equivalent, this part delivers AEC-Q101-qualified transient suppression for bidirectional signal paths, with halogen-free RoHS compliance, MSL Level 1 rating, and verified clamping performance under standardized surge waveforms.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast energy absorption during ESD or lightning-induced surges.
The device is rated for continuous operation from –55 °C to +150 °C junction temperature and exhibits a typical thermal resistance of 15 °C/W (junction-to-lead), making it suitable for high-reliability PCB layouts with minimal copper pad area (0.31" × 0.31"). Its 10/1000 μs waveform response time is sub-nanosecond, with clamping voltage tightly specified at IPPM.
Key Specifications

Pinout & Package
SMCJ58CAHM3_A/H is a two-terminal bidirectional TVS diode in SMC (DO-214AB) package. No polarity marking is present on the case, as conduction occurs identically in both directions. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | Either terminal serves as input/output for transient energy; no DC polarity dependency; connects across protected line and ground or between differential pairs. |
| Case (body) | Non-electrical mechanical interface | Thermally conductive plastic body with UL 94 V-0 rating; provides mechanical stability and flame resistance without electrical isolation requirement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58CAHE3_A/H | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable only for lower-energy transients (IEC 61000-4-2, not IEC 61000-4-5) | Select when board space is constrained and surge threat level is limited to ESD or capacitive coupling. |
| SMCJ58CA-E3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and RoHS-compliant without halogen-free certification | Approved for industrial/commercial use only; not qualified for automotive under-hood deployment | Choose for cost-sensitive non-automotive designs where AEC-Q101 and halogen-free status are not mandated. |

FAQ
What is the clamping voltage of SMCJ58CAHM3_A/H at its rated peak pulse current?
The SMCJ58CAHM3_A/H clamps to a maximum of 93.6 V when subjected to its rated 16.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024. The clamping voltage directly determines the maximum overvoltage stress imposed on protected circuitry during surge events, making it a critical parameter for system-level reliability validation. SMCJ58CAHM3_A/H maintains this specification across its full operating temperature range.
Is SMCJ58CAHM3_A/H suitable for automotive under-hood applications?
Yes, SMCJ58CAHM3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +150 °C, making it suitable for under-hood automotive applications including engine control modules, transmission sensors, and battery management system interfaces. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support high-volume automotive manufacturing requirements. The SMCJ58CAHM3_A/H datasheet explicitly lists AEC-Q101 qualification in the ordering information table and mechanical data section.
How does the bidirectional configuration of SMCJ58CAHM3_A/H affect its PCB layout?
The bidirectional configuration of SMCJ58CAHM3_A/H eliminates polarity marking and allows placement across any two nodes requiring symmetrical transient suppression-such as differential signal pairs or AC-coupled lines-without orientation constraints. Unlike unidirectional TVS diodes, SMCJ58CAHM3_A/H has no cathode band, simplifying automated optical inspection and reducing assembly errors. Its SMC (DO-214AB) package requires only standard 0.31" × 0.31" copper pads per terminal, with no special grounding or routing rules beyond minimizing trace inductance to preserve clamping speed.
What is the maximum reverse leakage current for SMCJ58CAHM3_A/H at its standoff voltage?
The maximum reverse leakage current (ID) for SMCJ58CAHM3_A/H is 1.0 μA at its 58 V standoff voltage (VWM), tested at TA = 25 °C. This low leakage ensures minimal impact on high-impedance circuits such as sensor bias networks or battery-monitoring inputs. The value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number: 88394), and remains stable across temperature due to the device's glass-passivated junction and tight process control.
Does SMCJ58CAHM3_A/H meet JEDEC moisture sensitivity requirements?
Yes, SMCJ58CAHM3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This classification means the device can be stored indefinitely at ambient conditions without baking prior to surface-mount assembly, supporting standard lead-free reflow profiles. The MSL Level 1 rating is explicitly stated in the "FEATURES" section of the Vishay datasheet and validated through JEDEC-standard preconditioning and solderability testing. SMCJ58CAHM3_A/H is therefore suitable for high-throughput automated manufacturing without moisture-related yield loss.
