Description
Key characteristics:
- Bidirectional operation: Clamps both positive and negative voltage spikes.
- Low clamping voltage: Limits excessive voltage to safe levels.
- Fast response time: Reacts quickly (nanoseconds) to transient events.
- RoHS compliant: Environmentally friendly.
Common applications include protecting power supplies, communication lines, and data interfaces from ESD (electrostatic discharge), lightning surges, and inductive load switching.
Package: DO-214AA (SMB).
Operating temperature: -55°C to +150°C.
A cost-effective solution for surge protection in consumer, industrial, and automotive systems.
Features
- Voltage Rating: 15V working standoff voltage.
- Bidirectional: Protects against both positive and negative voltage transients.
- Peak Pulse Power: 600W (8/20µs pulse).
- Low Clamping Voltage: Limits voltage spikes to safe levels.
- Fast Response Time: Reacts in nanoseconds (ps range).
- Package: SMB (DO-214AA) for compact PCB mounting.
- Applications: Protects sensitive electronics (e.g., power supplies, data lines) from ESD, lightning, and inductive surges.
Ideal for automotive, industrial, and telecom systems requiring robust surge protection.
Pinout
- Pin Count: 2 pins (standard SMB package).
- Function: Protects circuits from voltage spikes by clamping transient voltages to a safe level (15V breakdown voltage). It operates bidirectionally, meaning it can handle both positive and negative voltage transients.
Key Parameters:
- Standoff Voltage (V_RWM): 15V
- Breakdown Voltage (V_BR): 16.7V (min)
- Peak Pulse Current (I_PP): High (varies by standard, e.g., 24.2A per IEC 61000-4-5).
Commonly used in power lines, data interfaces, and ESD protection.
Manufacturer
The SMBJ15CA is designed to protect sensitive circuits from voltage spikes and transients, commonly used in power supplies and communication systems. Littelfuse is recognized for its innovation and quality in semiconductor and protection devices.
Application
1. Electronics Protection: Safeguards sensitive components in power supplies, communication devices, and data lines from voltage spikes.
2. Automotive Systems: Protects ECUs, sensors, and infotainment systems from load dump and ESD events.
3. Industrial Equipment: Shields control systems, PLCs, and motor drives from surges.
4. Telecom & Networking: Ensures reliability in routers, switches, and base stations against lightning-induced transients.
5. Consumer Electronics: Guards USB ports, HDMI interfaces, and charging circuits from ESD.
Its 15V clamping voltage makes it ideal for low-voltage circuit protection.
