Product details
Overview
SMCJ6.0CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and clamps to ≤10.3 V at 145.6 A (10/1000 μs waveform), making it suitable for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMCJ6.0CA-E3/57T datasheet, SMCJ6.0CA-E3/57T pinout, SMCJ6.0CA-E3/57T application, or SMCJ6.0CA-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 (via HE3 suffix), and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ6.0CA-E3/57T operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior-identical electrical characteristics in both polarities. Its glass-passivated junction ensures stable breakdown and low leakage (<1000 μA at VWM), while its low incremental surge resistance enables fast response to transient events such as ESD, inductive switching spikes, and lightning-induced surges.
Designed for surface-mount use on PCBs with minimum recommended pad layout (0.31" × 0.31" copper per terminal), it supports operation from −55 °C to +150 °C junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0B-TB | Lower PPPM (500 W), higher VWM (5.0 V), same SMC package but not AEC-Q101 qualified | Targeted at cost-sensitive consumer electronics; insufficient for automotive load dump or industrial surge testing | Select only for non-automotive, low-energy transient environments where 1500 W rating is unnecessary |
| SMCJ6.0A-E3/57T | Unidirectional variant; identical VWM/VBR/PPPM but asymmetric conduction (cathode-banded); VF = 3.5 V at 100 A | Required only for DC-biased lines where reverse conduction must be blocked (e.g., power supply outputs) | Choose only when polarity-aware clamping is mandatory; otherwise SMCJ6.0CA-E3/57T offers broader design flexibility |
Compared with SAC5.0B-TB and SMCJ6.0A-E3/57T, the SMCJ6.0CA-E3/57T uniquely delivers bidirectional 1500 W surge immunity in an AEC-Q101-eligible package-making it the sole choice for automotive sensor hubs and industrial fieldbus nodes requiring symmetrical protection without polarity constraints.

FAQ
What is the clamping voltage of the SMCJ6.0CA-E3/57T under full-rated surge conditions?
The SMCJ6.0CA-E3/57T clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 145.6 A using the standard 10/1000 μs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 0.31" × 0.31" copper pads) and represents the upper limit of voltage imposed on the protected circuit during worst-case surge events. The SMCJ6.0CA-E3/57T maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is the SMCJ6.0CA-E3/57T suitable for automotive applications?
Yes-the SMCJ6.0CA-E3/57T is RoHS-compliant and compatible with AEC-Q101 qualification when ordered with the HE3 or HM3 suffix (e.g., SMCJ6.0CAHE3_A/H). While the -E3/57T variant itself is commercial-grade, its electrical specs-including 1500 W PPPM, 150 °C TJ max, and robust surge current handling-align with automotive subsystem requirements such as body control modules and sensor interfaces. For certified automotive use, specify the HE3-suffixed version of the SMCJ6.0CA-E3/57T.
How does the SMCJ6.0CA-E3/57T differ from the unidirectional SMCJ6.0A-E3/57T?
The SMCJ6.0CA-E3/57T is bidirectional with identical electrical characteristics in both polarities and no polarity marking, whereas the SMCJ6.0A-E3/57T is unidirectional, features a cathode band, and conducts only in reverse bias-forward conduction exhibits VF ≈ 3.5 V at 100 A. Both share the same VWM (6.0 V), VBR range (6.67–7.37 V), PPPM (1500 W), and SMC package. The SMCJ6.0CA-E3/57T is preferred for AC-coupled, floating, or polarity-agnostic lines; the unidirectional version suits DC rails where forward conduction must be blocked.
What is the thermal resistance of the SMCJ6.0CA-E3/57T, and how does it affect PCB layout?
The SMCJ6.0CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended pad layout-0.31" × 0.31" (8.0 mm × 8.0 mm) copper areas per terminal. This value assumes no additional heatsinking; larger copper pours or internal planes reduce RθJA significantly. For sustained power dissipation or high-temperature environments, designers should verify junction temperature using PD = 6.5 W and ambient conditions, as exceeding 150 °C TJ risks parametric shift or failure. The SMCJ6.0CA-E3/57T's thermal profile directly impacts placement near heat sources and copper area allocation.
Does the SMCJ6.0CA-E3/57T meet industry surge immunity standards like IEC 61000-4-5?
Yes-the SMCJ6.0CA-E3/57T's 1500 W peak pulse power rating corresponds to the 10/1000 μs waveform defined in IEC 61000-4-5, enabling it to handle combination wave surges up to 4 kV line-to-earth when implemented with proper PCB layout (e.g., short traces, ground plane coupling, and adequate copper pour). Its low clamping voltage (≤10.3 V) and fast response ensure downstream ICs remain within safe operating limits during standardized surge tests. System-level compliance requires validation with the full protection network-including series impedance and filtering-but the SMCJ6.0CA-E3/57T forms the foundational clamping element in such architectures.
