Overview
Description
### Key Features:
- Bidirectional clamping: Protects against both positive and negative voltage surges.
- Peak pulse power: 400W (8/20µs waveform).
- Breakdown voltage (VBR): ~40V (min).
- Clamping voltage (VC): ~58.1V at 1A.
- Low leakage current: <1µA at working voltage.
- Fast response time: <1ns.
### Applications:
- ESD protection for data lines, power supplies, and communication ports (USB, Ethernet, etc.).
- Surge suppression in automotive, industrial, and consumer electronics.
### Package:
- DO-214AC (SMA) surface-mount package.
The SMAJ36A is robust, cost-effective, and widely used for transient protection in circuits operating near 36V. Always verify datasheet specs for exact parameters.
Features
- Voltage Rating: Standoff voltage 36V, breakdown voltage 40V (min).
- Peak Pulse Power: 400W (8/20µs pulse).
- Low Clamping Voltage: 58.1V at 10A (minimizes damage to protected circuits).
