Product Overview
MP174AGS-Z is the SOIC-8 reel-orderable of MPS's MP174A 700 V non-isolated offline regulator. The device uses primary-side constant-voltage control and an integrated high-voltage MOSFET to support low-power buck, buck-boost, boost and flyback implementations.
MPS lists up to 5 W output power, less than 250 mA maximum DCM output current and less than 400 mA maximum CCM output current as family-level capability figures. Those current limits describe different conduction modes and should not be merged into one continuous-current rating.
Confirmed Electrical Data

| Protection | OTP, UVLO, OLP, SCP, open-loop detection (family protection features) |
| Package | SOIC-8 (GS exact package code) |
| Packing | Z reel-size option (P and Z denote reel-size choices for the same part) |
Selection Notes
This exact orderable belongs to the MP174A family; do not substitute specifications from the older MP174 family.
The <250 mA DCM and <400 mA CCM figures apply to different conduction modes, not two simultaneous ratings.
The integrated 700 V MOSFET rating is a device capability and is not the same as a recommended continuous line-input voltage.
MPS marks MP174A Active; the Z suffix is a reel-size code, not an electrical variant.
Lifecycle and Procurement Context
MPS lifecycle status for this family/orderable context is Active. Lifecycle status is included for procurement planning and does not imply HKEQGOO stock, lead time or delivery availability.
