Overview
SMA5J6.0CAHE3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 48.5 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J6.0CAHE3/5A datasheet, SMA5J6.0CAHE3/5A pinout, SMA5J6.0CAHE3/5A application, or SMA5J6.0CAHE3/5A equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.72), RoHS-compliant and halogen-free construction, MSL Level 1 rating, and suitability for 12 V automotive bus and sensor I/O protection.
Technical Context
This device operates symmetrically in both directions due to its bidirectional junction structure, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated chip junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping under repetitive surges.
The SMA5J6.0CAHE3/5A delivers 500 W peak pulse power with a 10/1000 µs waveform while maintaining a low thermal resistance (RθJA = 80 °C/W) when mounted on 5.0 mm × 5.0 mm copper pads. It supports operating junction temperatures from –55 °C to +150 °C and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications

Use Scenario: Protecting 12 V supply rails in automotive ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed at board entry point, shunting surge energy to ground before it reaches DC-DC converters and microcontrollers. Use Value: Withstands 500 W surges while limiting clamped voltage to 10.3 V, preventing latch-up or damage to downstream 12 V tolerant ICs. |
Use Scenario: Safeguarding analog inputs of industrial pressure/temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pair (e.g., 4–20 mA loop or RS-485 bus) to suppress EFT and surge-induced common-mode noise. Use Value: Symmetrical clamping ensures equal protection for positive/negative transients; low leakage (<1 μA) avoids signal offset errors in precision measurement circuits. |
| Automotive CAN Bus Protection | Consumer USB Port ESD Protection |
|
Use Scenario: Shielding high-speed CAN FD transceivers (e.g., TCAN1042) from ESD and coupled transients in vehicle networking. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ ≈ 100 pF typical at 0 V) placed directly at connector pins to minimize stub length and preserve signal integrity. Use Value: Fast response time (<1 ns) and 10.3 V clamping prevent CAN bit errors or transceiver latch-up during ±8 kV contact ESD events (IEC 61000-4-2). |
Use Scenario: Adding secondary surge protection to USB 2.0 data lines (D+/D−) in smart home hubs exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS used in conjunction with primary ESD diodes to handle higher-energy threats beyond IEC 61000-4-2 level 4. Use Value: 500 W rating absorbs multi-pulse surge energy that would otherwise degrade or destroy low-capacitance ESD arrays; RoHS/halogen-free compliance meets consumer safety standards. |
Equivalent & Alternatives

FAQ
What does the "HE3" suffix indicate in SMA5J6.0CAHE3/5A?
The "HE3" suffix denotes that the SMA5J6.0CAHE3/5A is RoHS-compliant and AEC-Q101 qualified for automotive applications. It also specifies matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards, and JESD201 Class 2 whisker resistance. This distinguishes it from commercial-grade variants like SMA5J6.0CA-E3/5A.
Is SMA5J6.0CAHE3/5A unidirectional or bidirectional?
SMA5J6.0CAHE3/5A is a bidirectional transient voltage suppressor, as confirmed by the "CA" suffix in its part number and explicit documentation stating "Electrical characteristics apply in both directions." It has no polarity marking and functions identically for positive and negative transients.
What is the maximum clamping voltage of SMA5J6.0CAHE3/5A and at what current is it specified?
The maximum clamping voltage of SMA5J6.0CAHE3/5A is 10.3 V, measured at the peak pulse current (IPPM) of 48.5 A under a 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuitry during a 500 W surge event.
Does SMA5J6.0CAHE3/5A require special PCB layout considerations?
Yes - SMA5J6.0CAHE3/5A should be mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal to achieve rated 500 W pulse power and thermal performance. Short, direct traces to ground and protected line minimize inductance; avoid vias or narrow traces between the TVS and protected node to preserve clamping speed and effectiveness.
How does SMA5J6.0CAHE3/5A differ from SMA5J6.0AHE3/5A?
SMA5J6.0CAHE3/5A is bidirectional with symmetrical clamping, while SMA5J6.0AHE3/5A is unidirectional and features a cathode band marking. Their VWM (6.0 V), VBR, and PPPM are identical, but only the "CA" version supports AC or floating-line protection without polarity constraints - making SMA5J6.0CAHE3/5A essential for CAN, RS-485, or audio line applications.
