This value is measured per ANSI/IEEE C62.35 and verified across production lots. The SMCJ58CA-M3/57T maintains this clamping performance bidirectionally, ensuring consistent protection for both polarities of transient events.
Is the SMCJ58CA-M3/57T suitable for automotive applications?
Yes - the SMCJ58CA-M3/57T uses the M3 suffix indicating halogen-free, RoHS-compliant construction and is part of the AEC-Q101 qualified SMCJ family (e.g., SMCJ58CAHM3_X variants). While the base SMCJ58CA-M3/57T itself is not pre-certified, its process and test flow align with AEC-Q101 requirements, enabling straightforward qualification for automotive sensor and ECU protection. The SMCJ58CA-M3/57T operates reliably from −55 °C to +150 °C.
How does the SMCJ58CA-M3/57T differ from unidirectional SMCJ58A-M3/57T?
The SMCJ58CA-M3/57T is bidirectional with symmetrical clamping in both directions and no cathode band marking, whereas the unidirectional SMCJ58A-M3/57T has a marked cathode and conducts only in reverse bias. Their VWM (58 V), VBR, and PPPM (1500 W) are identical, but the SMCJ58CA-M3/57T is required for AC-coupled, differential, or polarity-agnostic protection schemes. Layouts for the SMCJ58CA-M3/57T do not require orientation verification.

The SMCJ58CA-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on standard 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, designers must ensure adequate copper area and avoid thermal bottlenecks. The SMCJ58CA-M3/57T also features RθJL = 15 °C/W, meaning thermal performance improves significantly with direct lead-to-plane connections.
Does the SMCJ58CA-M3/57T meet UL safety standards?
Yes - the SMCJ58CA-M3/57T carries Underwriters Laboratories recognition under UL 497B (file E136766) for both unidirectional and bidirectional transient protectors.
