DFLT51A-7 DIODES Circuit Protection

The DFLT51A-7 from Diodes Incorporated is an AEC-Q101 qualified unidirectional TVS diode designed for robust transient voltage suppression in automotive and industrial electronics. For selection, its key specifications are a 51V reverse standoff voltage protecting 48V rails, a precise minimum 56.7V breakdown voltage, and a low 82.4V clamping voltage at a 2.73A peak pulse current. It delivers 225W of peak pulse power in a compact footprint. The wide -65°C to +150°C operating range and AEC-Q101 qualification ensure reliability in extreme under-hood conditions. In application, it is specifically engineered to protect sensitive circuits from switching and load dump surges per ISO 16750-2. It excels in protecting 48V mild-hybrid battery management systems, electric power steering ECUs, and transmission control units. Its compact PowerDI™ 123 package makes it ideal for space-constrained automotive sensors, motor controllers, and industrial PLCs where reliable high-voltage protection is critical.
