Product details
Overview
SMA5J6.0CAHE3/61 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) at 10 mA, 500 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 48.5 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J6.0CAHE3/61 datasheet, SMA5J6.0CAHE3/61 pinout, SMA5J6.0CAHE3/61 application, or SMA5J6.0CAHE3/61 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 80 °C/W), RoHS-compliant AEC-Q101 qualification status, and real-world protection use cases in automotive sensor interfaces and industrial I/O circuits.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (6.67–7.37 V), ID ≤ 800 µA at VWM, and VC = 10.3 V at IPPM = 48.5 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device is rated for TJ = –55 °C to +150 °C, has RθJL = 25 °C/W, and is mounted on 5.0 mm × 5.0 mm copper pads per terminal. Unlike unidirectional variants, SMA5J6.0CAHE3/61 carries no polarity marking and delivers symmetrical clamping in either direction - critical for AC-coupled or differential bus protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for 5 V logic or CAN FD signal lines. |
| VBR (min/max) | 6.67 V / 7.37 V at IT = 10 mA - Tight breakdown window ensures predictable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamping voltage limits downstream IC stress during 500 W surge; stays below 12 V absolute max for 5 V rail protection. |
| PPPM | 500 W (10/1000 µs) - Sustains high-energy transients from inductive switching or ESD events without degradation. |
| ID @ VWM | ≤ 800 µA - Low leakage preserves signal integrity and battery life in always-on automotive modules. |
| TJ max. | +150 °C - Enables placement near hot components (e.g., power MOSFETs, motor drivers) without derating concerns. |
| RθJA | 80 °C/W - Requires minimum 5 mm × 5 mm Cu pad per terminal for thermal management; validates PCB layout guidance in datasheet fig. 2. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional - no cathode band marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); matte tin-plated leads, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional current path | No polarity designation - terminals are interchangeable; enables single-component protection on AC, differential, or floating lines. |
| Case (body) | Thermal and mechanical interface | Non-electrical; transfers heat to PCB copper; requires full-surface solder mask defined pad for RθJA compliance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (HTOL, TC, UHAST); supports under-hood and ADAS sensor module deployment. |
| Glass passivated junction | Ensures stable VBR and low ID over temperature and lifetime; eliminates risk of moisture-induced parameter drift. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without pre-baking; reduces manufacturing complexity and cost. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients (e.g., ISO 7637-2 Pulse 1/2a/5a); improves clamping fidelity vs. higher-Rsurge TVS. |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed automotive and industrial enclosures. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt energy before it reaches PHY or ADC. Use Value: Withstands 500 W pulses while limiting clamped voltage to 10.3 V - below absolute maximum ratings of common automotive transceivers (e.g., TJA1042, SN65HVD230). |
Use Scenario: Safeguarding half-duplex RS-485 transceivers (e.g., MAX13487, THVD1550) against ESD and lightning-induced surges on field wiring. IC Role / Device Role / Timing Role: Common-mode TVS across A/B lines and to ground, leveraging symmetrical clamping to preserve differential signaling integrity. Use Value: 6.0 V VWM aligns with RS-485 common-mode range (–7 V to +12 V); 10.3 V VC prevents latch-up in transceivers with 13.2 V abs max supply rating. |
| Consumer USB-C Port Protection | Smart Meter Power Line Interface |
Use Scenario: Secondary-level surge suppression on USB-C CC and VCONN lines after primary GDT or MOV stage. IC Role / Device Role / Timing Role: Fast-response TVS absorbing residual transients that bypass front-end filtering; placed adjacent to connector. Use Value: Sub-1 ns response time and 800 µA ID at 6.0 V ensure minimal interference with 3 A PD negotiation signaling and 5 V VBUS monitoring. |
Use Scenario: Protecting microcontroller GPIOs and isolated power supply feedback paths in ANSI C12.19-compliant smart meters exposed to utility grid surges. IC Role / Device Role / Timing Role: Point-of-entry clamping on auxiliary 5 V or 3.3 V rails derived from transformer-coupled or capacitive power supplies. Use Value: AEC-Q101 qualification provides extended lifetime assurance (>15 years) under thermal cycling and humidity stress typical in outdoor meter installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0CA-M3/61 | Same electrical specs; halogen-free, RoHS-compliant, commercial grade (non-AEC-Q101). | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and halogen-free material is specified. |
| SMCJ6.0CAHE3/61 | Same VWM/VBR/VC but in larger SMC (DO-214AB) package; PPPM = 1500 W; RθJA = 35 °C/W. | Higher power handling and better thermal performance, but occupies ~2.5× PCB area; requires different pad layout. | Choose when system-level surge testing exceeds 500 W (e.g., ISO 16750-2 Pulse 5b) and board space allows SMC footprint. |
Compared with SMA5J6.0CAHE3/61, SMA5J6.0CA-M3/61 offers identical protection performance without AEC-Q101 validation, while SMCJ6.0CAHE3/61 trades compactness for 3× higher surge capacity and lower thermal resistance - enabling robust protection in space-tolerant, high-reliability industrial systems.

FAQ
What does the "CA" suffix indicate in SMA5J6.0CAHE3/61?
The "CA" suffix denotes a bidirectional configuration - meaning SMA5J6.0CAHE3/61 provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity. This eliminates need for polarity-aware placement and supports AC-coupled or differential signal line protection.
Is SMA5J6.0CAHE3/61 compatible with lead-free reflow processes?
Yes, SMA5J6.0CAHE3/61 meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable solder joint formation in standard Pb-free assembly lines without pre-baking.
How does SMA5J6.0CAHE3/61 differ from unidirectional SMA5J6.0AHE3/61?
SMA5J6.0CAHE3/61 is bidirectional with no polarity marking and symmetrical clamping; SMA5J6.0AHE3/61 is unidirectional with cathode band, rated for forward surge (IFSM = 40 A), and exhibits VF = 3.5 V at 25 A. The CA version lacks IFSM rating and forward conduction capability - it functions only as a clamp in either direction.
What is the maximum clamping voltage of SMA5J6.0CAHE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.0CAHE3/61 is 10.3 V at peak pulse current (IPPM) of 48.5 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Does SMA5J6.0CAHE3/61 require external series impedance for optimal protection?
No, SMA5J6.0CAHE3/61 is designed for direct placement at the protected node - however, optimal protection requires adherence to recommended pad layout (0.2" × 0.2" Cu per terminal) to maintain thermal performance and achieve rated PPPM. Series impedance (e.g., ferrite bead, resistor) may be added upstream to reduce di/dt but is not required for basic clamping function.
