Product details
Overview
SMBJ58CA-13-F from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in SMB package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 58 V reverse standoff voltage (VRWM), 64.4–74.6 V breakdown voltage (VBR) at 1 mA, 93.6 V maximum clamping voltage (VC) at 6.4 A peak pulse current, and 600 W peak pulse power dissipation - validated for IEC 61000-4-2 ESD and IEC 61000-4-5 surge immunity in industrial power supplies and automotive control modules.
For engineers reviewing the SMBJ58CA-13-F datasheet, SMBJ58CA-13-F pinout, SMBJ58CA-13-F application, or SMBJ58CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, unidirectional vs. bi-directional polarity requirements for AC-coupled interfaces, thermal derating above +25°C, and compatibility with 3,000-unit tape-and-reel automated assembly.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC signal paths, differential buses (e.g., RS-485, CAN), and dual-rail analog circuits without polarity constraints. Its glass-passivated junction ensures stable leakage (<5 µA at VRWM) and repeatable clamping performance under repetitive transients.
The device responds to 8.3 ms half-sine surges per IEC 61000-4-5, delivering 6.4 A peak pulse current (IPP) while limiting voltage to ≤93.6 V. Thermal derating follows a linear 4.8 W/°C slope above +25°C ambient, with junction temperature rated from –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 58.0 V - Maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected line operating voltage. |
| Breakdown Voltage (VBR) | 64.4–74.6 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering before downstream IC damage thresholds. |
| Clamping Voltage (VC) | 93.6 V @ 6.4 A - Peak voltage seen by protected circuit during 8.3 ms surge; defines worst-case stress on load. |
| Peak Pulse Power (PPK) | 600 W - Sustained for single non-repetitive 8.3 ms surge; validates compliance with Level 4 IEC 61000-4-5 (4 kV line-to-line). |
| Leakage Current (IR) | ≤5.0 µA @ VRWM - Minimal standby power loss and signal integrity impact in high-impedance sensing or battery-powered nodes. |
| Operating Temperature | –55°C to +150°C - Supports under-hood automotive, industrial motor drives, and outdoor telecom equipment deployment. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case compliant with UL 94V-0 flammability rating; dimensions: 4.06 × 3.30 × 2.21 mm (L × W × H); weight ≈ 0.1 g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bi-directional) | Reversible transient conduction path | No polarity marking; terminals function identically for positive or negative surges - simplifies PCB layout for AC or floating lines. |
| Cathode Band (N/A) | Not applicable | Bi-directional construction eliminates cathode band; no orientation dependency during placement or routing. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables single-device protection against 4 kV/2 Ω IEC 61000-4-5 surges on 12–48 V DC rails without parallel staging. |
| Glass-passivated die | Ensures long-term parameter stability and low parametric drift under thermal cycling and humidity exposure. |
| Bi-directional symmetry | Supports protection of differential pairs (e.g., CAN_H/CAN_L) with identical clamping in both directions - no need for dual unidirectional devices. |
| Lead-free & RoHS-compliant | Meets IPC-J-STD-020 reflow profiles and EU Directive 2011/65/EU; matte tin plating ensures solderability per MIL-STD-202, Method 208. |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |

Use Scenario: Transient suppression on A/B differential pair and common-mode shield in utility-grade metering interfaces. IC Role / Device Role: Bi-directional TVS bridging A–B and A–GND/B–GND to absorb common- and differential-mode surges. Use Value: Maintains signal integrity below 93.6 V clamping while supporting >10 kV ESD contact discharge per IEC 61000-4-2. |
Use Scenario: Input-stage protection of 3-phase meter auxiliary power supply (110/230 V AC rectified to ~320 V DC bus). IC Role / Device Role: Secondary clamp after MOV primary stage, absorbing residual energy and improving let-through voltage. Use Value: 600 W rating handles residual 10/1000 µs surges post-MOV clipping; 58 V VRWM allows use with 48 V intermediate rails in multi-output SMPS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA from Vishay (SMBJ58CA-E3/5A) | Identical VRWM (58 V), VBR (64.4–74.6 V), VC (93.6 V), and IPP (6.4 A); same SMB package and RoHS profile. | No functional deviation; validated for same IEC 61000-4-2/4-5 test levels and thermal derating curve. | Select when dual-sourcing is required; pin-to-pin and footprint compatible with no layout change. |
| P6SMB58CA from ON Semiconductor | Same VRWM (58 V) and bi-directional configuration, but lower PPK (600 W), higher VC (96.8 V @ 6.2 A), and wider VBR tolerance (64.4–81.3 V). | Higher clamping voltage reduces margin for 5 V-tolerant interface ICs; wider VBR increases risk of premature conduction near VRWM. | Acceptable only where clamping margin ≥10 V above protected rail; verify thermal performance at TL = +75°C due to differing PM(AV) spec. |
Compared with Vishay's SMBJ58CA, Diodes' version offers identical electrical behavior and sourcing flexibility; versus ON Semi's P6SMB58CA, it delivers tighter VBR control and lower clamping - critical for protecting 3.3 V or 5 V logic interfaces on shared power domains.

FAQ
What is the maximum clamping voltage of SMBJ58CA-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 93.6 V at 6.4 A peak pulse current (IPP), measured under the standardized 8.3 ms half-sine waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and defines the absolute upper voltage stress imposed on protected circuitry during surge events.
Is SMBJ58CA-13-F suitable for protecting a 48 V DC power rail?
Yes - its 58 V reverse standoff voltage (VRWM) provides a 10 V margin above nominal 48 V operation, ensuring minimal leakage (<5 µA) during steady-state conditions. The 93.6 V clamping voltage remains safely below typical 100 V-rated input capacitors and DC-DC controller absolute maximum ratings.
How does the bi-directional configuration affect PCB layout compared to unidirectional TVS diodes?
Bi-directional operation eliminates polarity marking and orientation constraints: the SMBJ58CA-13-F has no cathode band and can be placed in either direction on the PCB. This simplifies layout for differential signals (e.g., CAN, RS-485) and reduces assembly errors in high-volume manufacturing.
Does SMBJ58CA-13-F require derating for operation at elevated ambient temperatures?
Yes - its peak pulse power derates linearly at 4.8 W/°C above +25°C ambient, and steady-state power dissipation drops to 5.0 W at lead temperature (TL) = +75°C. Designers must apply thermal vias and copper area per Diodes' recommended pad layout to maintain safe junction temperatures under sustained surge duty cycles.
