Product details
Overview
SMCJ58CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR), and 1500 W peak pulse power (10/1000 µs). It clamps transients to ≤93.6 V at 16.0 A peak current and operates from −55 °C to +150 °C, targeting automotive sensor lines and industrial I/O interfaces.
For engineers reviewing the SMCJ58CA-E3/57T datasheet, SMCJ58CA-E3/57T pinout, SMCJ58CA-E3/57T application, or SMCJ58CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, SMC package thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on 8 mm × 8 mm copper pads.
Technical Context
The SMCJ58CA-E3/57T implements a silicon avalanche junction structure with glass passivation, enabling sub-nanosecond response to ESD and lightning-induced transients. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity concerns in AC-coupled or floating signal paths.
Designed for surface-mount use on PCBs with minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, it delivers 1500 W peak pulse power under JEDEC-standard 10/1000 µs waveform while maintaining low incremental surge resistance and stable clamping voltage up to 93.6 V at rated IPPM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR min/max | 64.4 V / 71.2 V at 1.0 mA - Verified breakdown threshold range ensuring consistent turn-on across production lots. |
| VC @ IPPM | 93.6 V at 16.0 A - Clamped voltage during full 1500 W surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| RθJA | 75 °C/W - Thermal resistance junction-to-ambient on standard pad layout; informs derating above 25 °C ambient. |

Use Value: Symmetric 64.4–71.2 V breakdown prevents skew in differential signaling during surge events. | Use Scenario: Adding secondary-level surge immunity to USB-C or barrel-jack inputs in smart home hubs and audio amplifiers. IC Role / Device Role: Low-leakage (1.0 µA) standby protector that remains transparent during normal 5–20 V operation but activates within nanoseconds during ESD. Use Value: Prevents latch-up or gate oxide damage in upstream DC-DC controllers without increasing quiescent power consumption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58CA | Lower PPPM (600 W), same VWM (58 V), smaller SMA package (DO-214AC) | Limited to lower-energy surges (IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3+ | Select when board space is constrained and surge threat level is limited to ESD and minor switching noise. |
| SMCJ58A-E3/57T | Unidirectional version; includes cathode band marking; identical VWM, VBR, and PPPM | Requires polarity-aware layout; not usable on AC or floating nodes without external diode pairing | Choose only for DC-biased lines where reverse conduction must be blocked, e.g., power rail protection with reverse polarity prevention. |
Compared with SAC58CA and SMCJ58A-E3/57T, the SMCJ58CA-E3/57T uniquely balances 1500 W surge capacity, bidirectional symmetry, and SMC thermal robustness-making it optimal for high-reliability industrial and automotive interfaces where layout flexibility and surge margin are critical.

FAQ
What does the "CA" suffix indicate in SMCJ58CA-E3/57T?
The "CA" suffix denotes a bidirectional configuration: the SMCJ58CA-E3/57T provides symmetrical transient suppression for both positive and negative voltage excursions, unlike unidirectional variants (e.g., SMCJ58A) which conduct only in reverse bias. This makes the SMCJ58CA-E3/57T ideal for AC-coupled lines, differential buses, or any application where polarity cannot be guaranteed. No cathode band marking is present on the SMCJ58CA-E3/57T package.
Is SMCJ58CA-E3/57T AEC-Q101 qualified?
The SMCJ58CA-E3/57T carries the E3 suffix, indicating RoHS-compliance and commercial-grade qualification. For full AEC-Q101 qualification, Vishay offers the SMCJ58CAHE3 variant (with HE3 suffix), which undergoes additional stress testing per AEC-Q101 standards. The SMCJ58CA-E3/57T itself is not AEC-Q101 qualified, though its construction and thermal specs align with automotive design practices.
What is the maximum clamping voltage of SMCJ58CA-E3/57T and how is it measured?
The SMCJ58CA-E3/57T has a maximum clamping voltage (VC) of 93.6 V, measured at its peak pulse current (IPPM) of 16.0 A under the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the operating temperature range and reflects worst-case voltage seen by downstream circuitry during a full-rated surge event.
Can SMCJ58CA-E3/57T replace SMCJ58A-E3/57T in an existing design?
The SMCJ58CA-E3/57T can replace the unidirectional SMCJ58A-E3/57T only if the circuit does not rely on forward conduction blocking-since the CA version conducts in both directions, it may interfere with DC biasing or rectification functions. Layout changes are unnecessary (same SMC package), but electrical validation is required to confirm no unintended conduction paths exist in the application.
What PCB pad layout is recommended for optimal thermal and surge performance of SMCJ58CA-E3/57T?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area for each terminal of the SMCJ58CA-E3/57T to achieve rated 1500 W pulse power and maintain RθJA = 75 °C/W. Use internal ground/power planes connected via multiple thermal vias under the pads to enhance heat dissipation during repetitive surge events.
