Product details
Overview
SMBJ58CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR), 93.6 V max clamping voltage (VC) at 6.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom equipment.
For engineers reviewing the SMBJ58CAHE3_B/H datasheet, SMBJ58CAHE3_B/H pinout, SMBJ58CAHE3_B/H application, or SMBJ58CAHE3_B/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and bidirectional clamping behavior critical for robust overvoltage protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (64.4–71.2 V), VC = 93.6 V at IPPM = 6.4 A, and low incremental surge resistance enabling fast, repeatable clamping during lightning-induced or inductive-switching transients. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and long-term reliability under repetitive surge stress.
Designed for surface-mount automation, it meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and is qualified to AEC-Q101 - confirming suitability for automotive electronics where transient immunity and solder-joint integrity are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 48 V DC bus or 56 V PoE+ lines. |
| VBR (min/max) | 64.4 V / 71.2 V - breakdown initiates within this band at 1 mA test current; ensures predictable turn-on without premature conduction. |
| VC @ IPPM | 93.6 V at 6.4 A - clamped voltage seen by protected circuit during 10/1000 µs surge; limits downstream stress to <94 V. |
| PPPM | 600 W - peak transient power dissipation capability; sustains single 10/1000 µs surges up to 600 W without failure. |
| ID @ VWM | <1 µA - ultra-low reverse leakage at rated standoff; avoids signal distortion or bias shift in high-impedance sensor paths. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical anode/cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA-M3/52 | Same electrical specs and SMB package; halogen-free, RoHS-compliant, but not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only. | Select when AEC-Q101 is not required and halogen-free compliance is mandated. |
| SAC58CA | Same VWM/VBR/VC ratings but in smaller SOD-123FL package; lower PPPM (400 W), higher RθJA (150 °C/W). | Lower surge handling and thermal performance; limited to low-energy interfaces like I²C or GPIO. | Choose only for space-constrained consumer designs where 400 W surge margin is sufficient. |

FAQ
What is the clamping voltage of SMBJ58CAHE3_B/H at its rated peak pulse current?
The SMBJ58CAHE3_B/H has a maximum clamping voltage (VC) of 93.6 V at its specified peak pulse current (IPPM) of 6.4 A under a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and guarantees that protected circuitry will not experience voltages exceeding 93.6 V during standardized surge events - a key parameter for ensuring downstream IC survival in industrial and automotive applications.
Is SMBJ58CAHE3_B/H qualified for automotive use?
Yes, SMBJ58CAHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and surge endurance - validating its reliability in automotive subsystems such as ADAS cameras, body control modules, and infotainment interfaces where transient immunity is mission-critical.
How does the bidirectional nature of SMBJ58CAHE3_B/H affect its placement on PCBs?
The SMBJ58CAHE3_B/H has no polarity marking and functions identically in either orientation, simplifying PCB layout for differential or AC-coupled lines. Unlike unidirectional TVS diodes, it requires no attention to cathode band alignment - reducing assembly errors and enabling direct placement across RS-485 buses, CAN FD lines, or Ethernet transformer center-taps without directional verification during SMT processing.
What is the thermal resistance of SMBJ58CAHE3_B/H, and how does it impact layout?
SMBJ58CAHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value dictates derating above 25 °C ambient: at 75 °C board temperature, its 600 W surge rating drops to ~400 W. Layout must therefore include adequate copper area and avoid thermal isolation to maintain clamping consistency during repetitive surge events.
Does SMBJ58CAHE3_B/H meet moisture sensitivity level requirements for lead-free reflow?
Yes, SMBJ58CAHE3_B/H meets MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be subjected to standard lead-free reflow profiles with a peak temperature of 260 °C without preconditioning or baking. This eliminates moisture-related popcorning risk and streamlines high-volume manufacturing for industrial and automotive electronics producers.
