Product details
Overview
SMCJ64CHE3/57T from Vishay General Semiconductor is a surface-mount, AEC-Q101-qualified, bi-directional transient voltage suppressor (TVS) in DO-214AB (SMCJ) package, with 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 103 V clamping voltage (VC) at 14.6 A IPPM - designed for automotive-grade overvoltage protection of power rails and signal lines.
For engineers reviewing the SMCJ64CHE3/57T datasheet, SMCJ64CHE3/57T pinout, SMCJ64CHE3/57T application, or SMCJ64CHE3/57T equivalent, this device delivers validated surge immunity per ISO 7637-2 and IEC 61000-4-5 in harsh environments, with RoHS-compliant matte tin leads, MSL Level 1 rating, and JESD 201 Class 2 whisker resistance.
Technical Context
The SMCJ64CHE3/57T operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical VBR min/max (71.1 V / 78.6 V at 1 mA) and clamping ratio (VC/VBR ≈ 1.30) ensure predictable voltage limiting during 10/1000 µs transients.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The device meets AEC-Q101 stress test requirements including temperature cycling, high-temperature operating life, and ESD (HBM ≥ 8 kV), confirming suitability for under-hood automotive electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; defines safe operating rail margin for 48 V systems. |
| VBR (min/max) | 71.1 V / 78.6 V at 1 mA - guaranteed avalanche onset range; ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 103 V at 14.6 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to <103 V under full-rated transient. |
| PPPM | 1500 W - peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 5a (load dump) events. |
| TJ max | +150 °C - maximum junction temperature; enables deployment in engine control units and power distribution modules. |
| Package | DO-214AB (SMCJ) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad footprint; compatible with automated reflow assembly. |
| Qualification | AEC-Q101 qualified - validated for automotive reliability including HTOL, TC, and ESD; HE3 suffix denotes automotive grade. |
Pinout & Package
SMCJ64CHE3/57T uses the DO-214AB (SMCJ) package: a surface-mount, bi-directional case with no polarity marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No polarity - terminals interchangeable; functions identically in either direction for AC or bidirectional DC line protection. |
| Case (cathode band absent) | Non-polarized package body | Confirms bi-directional configuration; eliminates orientation errors during placement and simplifies PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use - includes 1000-cycle temperature cycling (-40 °C to +125 °C) and 1000-hour HTOL at 150 °C. |
| 1500 W peak pulse power | Withstands ISO 7637-2 Pulse 5a (load dump) surges up to 1500 W without degradation when mounted on 8 mm × 8 mm copper pads. |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes overvoltage exposure to protected ICs - e.g., keeps microcontroller I/O below 103 V during 14.6 A transient. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-induced damage or delamination. |
| RoHS-compliant HE3 suffix | Meets EU Directive 2011/65/EU and JEDEC JS709A halogen-free requirements; suitable for Tier 1 automotive supply chains. |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|

Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in factory automation PLCs from EFT and surge coupling via long cables. IC Role / Device Role / Timing Role: Low-capacitance bi-directional clamp on differential RS-485 or 4–20 mA loop lines. Use Value: Maintains signal integrity with <1 µA leakage at 64 V and fast response (<1 ns), avoiding false triggering in precision measurement circuits. |
| Telecom Power Feeds | Consumer USB-C PD Ports |
|
Use Scenario: Overvoltage safeguard on -48 V telecom rectifier outputs exposed to lightning-induced surges on outside plant wiring. IC Role / Device Role / Timing Role: Primary-level TVS on DC input bus upstream of hot-swap controllers and PMICs. Use Value: Survives repeated 10/1000 µs surges up to 14.6 A with <5% parameter shift after 1000 pulses - verified per IEC 61000-4-5. |
Use Scenario: Secondary-side surge protection on USB-C VBUS lines in portable docking stations handling up to 100 W PD. IC Role / Device Role / Timing Role: Bi-directional clamp between VBUS and ground, rated for 64 V working voltage to accommodate 20 V PD3.1 extended range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC64AHE3/57T | Lower PPPM (600 W), same VWM (64 V), smaller DO-214AC (SMA) package; higher RθJA (125 °C/W). | Targeted at space-constrained consumer ports; insufficient for automotive load dump. | Select only for cost-sensitive, non-automotive designs where 600 W surge margin is adequate. |
| SMCJ64AHE3/57T | Uni-directional variant (cathode-banded); identical VWM, VBR, VC, and PPPM; same DO-214AB package. | Required where DC polarity is fixed and reverse conduction must be blocked (e.g., 12 V battery inputs). | Choose SMCJ64AHE3/57T if circuit topology mandates unidirectional blocking; otherwise SMCJ64CHE3/57T offers design flexibility. |
Compared with SAC64AHE3/57T and SMCJ64AHE3/57T, the SMCJ64CHE3/57T uniquely combines 1500 W surge capacity, bi-directional symmetry, and AEC-Q101 qualification - making it the only option among the three validated for automotive 48 V power distribution and ISO 7637-2 compliance.

FAQ
What is the clamping voltage of the SMCJ64CHE3/57T at its rated peak pulse current?
The SMCJ64CHE3/57T has a maximum clamping voltage (VC) of 103 V at 14.6 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components remain within safe voltage limits during surge events. The SMCJ64CHE3/57T achieves this with low incremental surge resistance and symmetrical bi-directional behavior.
Is the SMCJ64CHE3/57T suitable for automotive applications?
Yes, the SMCJ64CHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its construction features glass-passivated junctions, JESD 201 Class 2 whisker resistance, MSL Level 1 reflow compatibility, and validated performance across -55 °C to +150 °C. The SMCJ64CHE3/57T is commonly deployed in ADAS ECUs, body control modules, and 48 V power distribution units.
How does the SMCJ64CHE3/57T differ from the uni-directional SMCJ64AHE3/57T?
The SMCJ64CHE3/57T is bi-directional with no polarity marking, while the SMCJ64AHE3/57T is uni-directional and marked with a cathode band. Both share identical VWM (64 V), VBR (71.1–78.6 V), VC (103 V), and PPPM (1500 W), but only the SMCJ64AHE3/57T blocks reverse current. The SMCJ64CHE3/57T is preferred for AC-coupled or polarity-agnostic lines like CAN FD or differential sensor pairs.
What is the thermal resistance of the SMCJ64CHE3/57T?
The SMCJ64CHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads, and a junction-to-lead resistance (RθJL) of 15 °C/W. These values enable sustained power dissipation up to 6.5 W at TA = 50 °C and support reliable operation at TJ = 150 °C in thermally demanding applications such as automotive power modules.
Does the SMCJ64CHE3/57T meet RoHS and halogen-free requirements?
Yes, the SMCJ64CHE3/57T carries the HE3 suffix, indicating full compliance with RoHS Directive 2011/65/EU and JEDEC JS709A halogen-free standards. Its matte tin-plated leads satisfy J-STD-002 solderability requirements, and the molding compound meets UL 94 V-0 flammability rating - fulfilling environmental and safety mandates for global automotive and industrial deployments.
