Product details
Overview
SMBG58CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal or power lines. It features 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), 93.6 V maximum clamping voltage (VC) at 6.4 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG58CA-E3/52 datasheet, SMBG58CA-E3/52 pinout, SMBG58CA-E3/52 application, or SMBG58CA-E3/52 equivalent, key selection criteria include bidirectional surge protection capability, low clamping ratio (VC/VBR ≈ 1.42), MSL Level 1 reflow compatibility, and compliance with UL 497B for telecom/sensor line protection.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, IPPM, and VC specifications in either direction. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog inputs and high-speed data lines.
The device uses a planar junction structure housed in an SMBG (DO-215AA) thermally optimized package with RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C under repetitive 0.01% duty cycle surges.
Key Specifications

| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Ensures consistent breakdown threshold across production lot |
| VC @ IPPM | 93.6 V at 6.4 A - Limits downstream voltage stress during 600 W transient events |
| PPPM | 600 W (10/1000 µs) - Withstands automotive load-dump and ESD-induced surges per ISO 7637-2 |

| Automotive Sensor Interface | Industrial RS-485 Bus |
|---|---|
Use Scenario: Protecting CAN/LIN transceivers and analog sensor outputs (e.g., pressure, temperature) from battery transients and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between connector and transceiver input pins. Use Value: Prevents latch-up or damage to 5 V/3.3 V transceivers during ISO 7637-2 pulses while maintaining signal integrity via low capacitance (<100 pF). | Use Scenario: Guarding differential data lines in factory automation PLCs against induced lightning surges and ground potential differences. IC Role / Device Role / Timing Role: Common-mode TVS pair (one per line) referenced to local ground, absorbing common-mode transients up to ±1 kV. Use Value: Enables >1 Mbps RS-485 communication integrity by limiting line-to-ground voltage excursion to <94 V during 600 W surges. |
| Consumer USB Port Protection | Telecom DSL Line Interface |
Use Scenario: Safeguarding USB 2.0 D+/D− lines in portable chargers and docking stations from human-body-model ESD (±8 kV contact). IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at USB connector, shunting ESD current before it reaches PHY IC. Use Value: Maintains signal rise/fall times (<1 ns response) and keeps junction capacitance low enough (<100 pF) to avoid USB 2.0 eye diagram degradation. | Use Scenario: Protecting ADSL/VDSL line drivers and receivers from lightning-induced surges on twisted-pair telephone lines. IC Role / Device Role / Timing Role: Primary surge protector mounted at line entry point, coordinated with secondary GDT or MOV stages. Use Value: UL 497B recognition allows direct integration into certified telecom equipment without redesigning surge coordination networks. |
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-T | Same VWM/VBR/VC, but SMB (DO-214AA) package; RθJA = 110 °C/W vs. 100 °C/W | Lower thermal performance; less suitable for high ambient or high-duty-cycle surge environments | Select SMBG58CA-E3/52 when board space permits and higher thermal reliability is required. |
| 1.5KE58CA | Higher PPPM (1500 W), axial lead DO-201AE package; VC = 93.6 V same, but slower response due to wire-bond construction | Not SMT-compatible; unsuitable for automated assembly or high-frequency signal lines | Choose SMBG58CA-E3/52 for surface-mount designs requiring fast response and AEC-Q101 compliance. |
Compared with SMBJ58CA-T and 1.5KE58CA, SMBG58CA-E3/52 delivers superior thermal resistance, MSL Level 1 reflow readiness, and AEC-Q101 validation-making it optimal for automotive and high-reliability industrial SMT applications where footprint, thermal margin, and qualification rigor are prioritized.

FAQ
What is the clamping voltage of SMBG58CA-E3/52 and how is it measured?
The SMBG58CA-E3/52 has a maximum clamping voltage (VC) of 93.6 V, measured at its peak pulse current (IPPM) of 6.4 A using a 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a standardized surge event, ensuring protected components remain within safe operating limits. The SMBG58CA-E3/52 achieves this clamping performance consistently across both polarities due to its bidirectional architecture.
Is SMBG58CA-E3/52 suitable for automotive applications?
Yes, SMBG58CA-E3/52 is AEC-Q101 qualified and rated for operation from −55 °C to +150 °C, making it suitable for under-hood and cabin automotive applications including sensor interfaces, infotainment systems, and body control modules. Its bidirectional behavior, low leakage (<1.0 µA), and UL 497B recognition further support compliance with automotive EMC and safety standards. The SMBG58CA-E3/52 meets these requirements without derating in typical PCB layouts.
What does the "CA" suffix indicate in SMBG58CA-E3/52?
The "CA" suffix in SMBG58CA-E3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBG58A), the SMBG58CA-E3/52 has no polarity marking and functions identically regardless of voltage polarity-ideal for AC-coupled lines, differential buses, or floating references where directionality cannot be assumed.
How does SMBG58CA-E3/52 compare to unidirectional TVS diodes in circuit design?
SMBG58CA-E3/52 eliminates the need to orient the device during placement and supports protection of bidirectional signals like RS-485, CAN, or audio lines without external polarity management. Unidirectional types require correct cathode alignment and only protect against one polarity of surge; misplacement risks failure. The SMBG58CA-E3/52's symmetry simplifies layout, reduces BOM count, and improves field reliability-especially in high-mix manufacturing environments.
What packaging and reel options are available for SMBG58CA-E3/52?
SMBG58CA-E3/52 is supplied in 7-inch plastic tape-and-reel format (E3/52) with 750 units per reel, compatible with standard SMT pick-and-place equipment. The "E3" suffix indicates RoHS-compliant, industrial-grade matte tin plating; "52" specifies the 7″ reel size. Alternate formats include 13″ reels (E3/5B, 3200 units) and halogen-free variants (HM3), all sharing identical electrical and thermal specs. The SMBG58CA-E3/52 reel packaging supports high-volume automated assembly with J-STD-002 solderability compliance.
