The STR-Z2062 is a highly integrated power management IC (PMIC) designed for use in a wide range of applications, including consumer electronics, industrial control systems, and automotive electronics. As a key component in many modern devices, the STR-Z2062 plays a crucial role in managing power distribution, regulation, and conversion. In this article, we will provide an in-depth look at the STR-Z2062 datasheet, covering its features, specifications, and typical applications.
Because of its reliability and integrated nature, the STR-Z2062 is frequently found in:

The STR-Z2062 is a specialized power management IC manufactured by Sanken, serving a critical role as an integrated PWM controller and power switch in switching power supplies, with its most famous application being in various HP LaserJet printers. While finding an official datasheet directly from the manufacturer is challenging, the information compiled here, combined with similar STR-Z series datasheets, can provide a solid basis for understanding the component's functionality and implementing repairs.
If you are replacing the STR-Z2062, be aware that the power supply board contains high-voltage capacitors (up to 300V-400V). A technician on a Dutch forum noted that a dead printer had 310V on the pins of the IC but nothing on the secondary side. That much voltage can cause serious injury if the capacitors are not properly discharged before handling. The STR-Z2062 is a highly integrated power management
Receives low-voltage DC (typically 12V–20V) from the transformer auxiliary winding after initial startup. High-Voltage Startup
The most prominent application of the STR-Z2062 is within the power supply units (PSUs) of various HP LaserJet printers. Because of its reliability and integrated nature, the
This IC is frequently sought after by technicians for fixing common printer power issues:
The STR-Z2062 datasheet suggests several potential applications, including:
When a printer becomes completely "dead" (no lights, no fan, no display activity), the root cause is almost always an SMPS failure. Because the STR-Z2062 acts as the main gateway for high-voltage switching, it bears the highest electrical stress and is prone to damage from power surges. Symptoms of a Blown STR-Z2062 The printer fails to turn on entirely.
