REMOTE RADIO HEAD DC POWER SUPPLY Overvoltage Protection for Mobile Broadband Infrastructure Objective Product Design Kit PTVS3-076C-SH TEL-NOTEKIT-1 The DC supply to a remote radio head requires robust and extremely reliable surge protection. Sensitive electronics must be protected from severe overvoltage conditions. The Bourns® SMD Power TVS Diode offers bidirectional overvoltage protection for DC power supplies through a reliable clamping action. Solution 1 Power TVS (PTVS) Diode: PTVS3-076C-SH Features & Benefits + The highlighted device supports a standoff voltage of 76 V. Surge voltages are clamped at a low level above this voltage. The device is RoHS compliant* and handles repeated surges with a peak of 3 kA (per IEC 61000-4-5, 8/20 µs). The reduced inductance of the SMD package leads results in superior clamping performance. DC Power System PTVS3-076C-SH Powered Equipment or Module – Note: Additional voltage and current ratings are available. The schematic shown here illustrates the application protection and does not constitute the complete circuit design. Customers should verify actual device performance in their specific applications. *RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.
