What are the key features of PESD24VL1BA?
- Bidirectional TVS protection with 27.8 V nominal breakdown and 70 V clamping voltage shields 24 V interfaces from transient overvoltage events
- 200 W peak pulse power handling (8/20 µs waveform) provides robust ESD and surge protection on industrial and automotive signal lines
- Low capacitance design preserves signal integrity on high-speed data lines where parasitic loading degrades edge rates above 10 MHz
- Compact UMD 2-pin package enables minimal PCB area ESD protection placement close to connector pins for optimal clamping response
- Silicon TVS construction offers sub-nanosecond response time, clamping transients before sensitive downstream ICs can be damaged
What is PESD24VL1BA used for?
The PESD24VL1BA is used for ESD and transient voltage protection on 24 V industrial fieldbus interfaces such as RS-485, CAN bus, and 4–20 mA analog signal lines in PLC and sensor transmitter circuits. Its bidirectional clamping and 200 W pulse capability also protect automotive ECU power supply pins and battery management system interfaces against load dump and lightning-induced transients. The low-capacitance UMD package suits compact PCB designs where multiple protection devices must be placed at connector entries without degrading high-frequency signal performance.

Frequently Asked Questions
What breakdown and clamping voltages does PESD24VL1BA provide for protecting 24 V industrial interfaces?
The PESD24VL1BA has a nominal breakdown voltage of 27.8 V (with 25.4 V min and 30.3 V max) and a maximum clamping voltage of 70 V. This makes it well-matched for 24 V industrial signal lines, where the standoff voltage is comfortably above the 24 V operating rail and the 70 V clamp keeps transients well below the breakdown ratings of typical 100 V-rated downstream components.
How much peak pulse power can PESD24VL1BA absorb, and what transient waveform does this rating apply to?
PESD24VL1BA is rated for 200 W peak pulse power based on the standard 8/20 µs waveform, which simulates ESD and lightning-induced surge events. This 200 W rating is sufficient to absorb typical industrial transients and ESD strikes defined under IEC 61000-4-2, protecting CAN bus transceivers, RS-485 line drivers, and analog signal conditioners from damage.
Why is the low capacitance characteristic of PESD24VL1BA important for fieldbus and high-speed signal lines?
TVS diodes placed on signal lines add parasitic capacitance that attenuates high-frequency signal components and degrades waveform edge rates. The low capacitance of PESD24VL1BA minimizes this loading effect on interfaces operating above 1 MHz to 10 MHz, such as CAN FD at 5 Mbit/s or RS-485 multidrop networks, allowing ESD protection without compromising the signal bandwidth required for reliable data transmission.
For a compact PCB layout protecting multiple 24 V I/O lines, how does the UMD package of PESD24VL1BA help?
The UMD (Ultra Minimold Diode) 2-pin package of PESD24VL1BA has a very small footprint — comparable to an SOD-882 or smaller — enabling designers to place one TVS device per I/O pin immediately adjacent to the connector without consuming significant PCB area. On a board with 8 or more protected 24 V lines, using UMD packages instead of larger SOD-123 or SMA packages can save several square centimeters of PCB area while maintaining the same per-channel 200 W transient protection.
