Product details
Overview
1.5SMC62CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power with 10/1000 μs waveform, 62 V breakdown voltage (VBR min/max: 58.9 V / 65.1 V), and clamping voltage of 85.0 V at 17.6 A peak pulse current - deployed for surge protection on automotive sensor signal lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the 1.5SMC62CA-E3/57T datasheet, 1.5SMC62CA-E3/57T pinout, 1.5SMC62CA-E3/57T application, or 1.5SMC62CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical avalanche behavior in both polarities, enabling robust suppression of ±62 V transients without polarity dependency. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the DO-214AB package provides thermal performance with RθJA = 75 °C/W and RθJL = 15 °C/W.
Designed for repetitive surge events at 0.01 % duty cycle, it sustains 1500 W peak pulse power under standardized 10/1000 μs waveform conditions and derates linearly above TA = 25 °C per Fig. 2. Reverse leakage remains ≤1.0 μA at 53.0 V stand-off voltage (VWM), supporting low-power system integrity during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - defines guaranteed avalanche onset range for bidirectional clamping at 1.0 mA test current |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage limiting transient overshoot during 1500 W surge event |
| PPPM | 1500 W - peak pulse power handling capacity with 10/1000 μs waveform, critical for lightning/inductive-switching immunity |
| IPPM | 17.6 A - maximum non-repetitive peak pulse current supported under standard waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount outline with 0.320" × 0.246" footprint, optimized for thermal dissipation and automated assembly |
Pinout & Package
Package: SMC (DO-214AB), molded case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints |
| 1500 W peak pulse power | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive interfaces |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak, eliminating bake-out prior to assembly |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage across temperature and lifetime |
| RoHS-compliant (E3 suffix) | Meets EU Directive 2011/65/EU with matte tin terminations compatible with lead-free and SnPb processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), same VBR range (60.8–67.2 V), SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when board space is constrained and surge energy is ≤600 W |
| 1.5KE62CA | Through-hole TO-204AA (DO-41), identical electrical specs but incompatible with SMT assembly | Requires wave soldering or hand-soldering; not viable for high-volume automated production | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CA-E3/57T delivers full 1500 W surge handling in an SMT-optimized package with MSL Level 1 compatibility - making it the preferred choice for automotive-grade, high-reliability surface-mount deployments requiring zero reflow risk and validated lightning immunity.

FAQ
What does the "CA" suffix indicate in 1.5SMC62CA-E3/57T?
The "CA" suffix in 1.5SMC62CA-E3/57T denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., 1.5SMC62A), this part has no cathode marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or floating signal paths.
Is 1.5SMC62CA-E3/57T qualified to AEC-Q101?
The base 1.5SMC62CA-E3/57T is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified. For automotive-grade qualification, Vishay offers the variant 1.5SMC62CAHE3_A/H (with HE3 suffix), which carries full AEC-Q101 certification. Engineers requiring automotive reliability must specify the HE3 or HM3 suffix versions - the E3/57T variant meets industrial and telecom standards but lacks stress-test validation for automotive temperature cycling and humidity testing.
What is the maximum clamping voltage of 1.5SMC62CA-E3/57T and how is it measured?
The maximum clamping voltage (VC) of 1.5SMC62CA-E3/57T is 85.0 V, measured at 17.6 A peak pulse current (IPPM) using a standardized 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is verified per Fig. 1 and Fig. 3 in the Vishay 88303 datasheet - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can 1.5SMC62CA-E3/57T be used in place of a unidirectional TVS like 1.5SMC62A?
No - 1.5SMC62CA-E3/57T cannot directly replace 1.5SMC62A in unidirectional applications without circuit review. While both share identical VBR and VC values, the CA version lacks polarity marking and conducts equally in both directions, potentially shorting DC bias rails if incorrectly applied. Use 1.5SMC62CA-E3/57T only where bidirectional clamping is explicitly required, such as across differential lines or AC signals.
What PCB pad layout is recommended for optimal thermal performance of 1.5SMC62CA-E3/57T?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area per terminal for 1.5SMC62CA-E3/57T to achieve rated 1500 W pulse power and maintain RθJA = 75 °C/W. Smaller pads cause thermal derating per Fig. 2; for high-reliability automotive use, internal copper planes and thermal vias beneath pads are strongly advised to sustain junction temperatures below +150 °C during repetitive surge events.
