Product details
Overview
UPA1526H-AZ from Renesas Electronics is a dual N-channel MOSFET optimized for high-efficiency DC-DC converter primary-side switching in notebook PC and portable device power supplies. It features 30 V VDSS, 7.5 A continuous drain current (ID), and 28 mΩ typical RDS(on) at VGS = 10 V, enabling low conduction loss in synchronous buck topologies.
For engineers reviewing the UPA1526H-AZ datasheet, UPA1526H-AZ pinout, UPA1526H-AZ application, or UPA1526H-AZ equivalent, key selection criteria include its dual common-drain configuration, thermally enhanced HSOP6 package, gate threshold voltage range (1.0–2.5 V), and specified avalanche energy rating (EAS = 45 mJ).
Technical Context
The UPA1526H-AZ integrates two matched N-channel enhancement-mode MOSFETs in a single HSOP6 package with shared source terminals and independent gate inputs-enabling use as synchronous rectifier pair or high-side/low-side driver in compact point-of-load converters. Its gate charge (Qg = 12 nC typ.) and output charge (Qoss = 19 nC typ.) are optimized for 500 kHz–1 MHz switching frequencies.
Designed for operation with 3.3 V or 5 V logic-level gate drive, the device supports standard PWM control without level-shifting. The internal body diodes exhibit reverse recovery time (trr) of 35 ns and Qrr of 15 nC, reducing switching losses during dead-time transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage; suitable for 12 V input rails with margin. |
| RDS(on) @ VGS=10 V | 28 mΩ typ. - Low conduction loss per channel; enables <1 W total FET loss at 5 A load. |
| ID (continuous) | 7.5 A - Rated current per channel at Tc = 25°C; derates to ~4.5 A at 85°C case temperature. |
| Qg | 12 nC typ. - Total gate charge; determines required gate driver peak current for fast turn-on. |
| EAS | 45 mJ - Single-pulse avalanche energy rating; supports robustness against inductive switching transients. |
| trr | 35 ns - Body diode reverse recovery time; minimizes shoot-through risk in synchronous rectification. |
Pinout & Package
UPA1526H-AZ is housed in a thermally enhanced HSOP6 (Heat Sink Outlined Package, 6-pin) with exposed thermal pad on underside. Package dimensions: 4.9 × 6.0 × 1.0 mm; recommended PCB land pattern includes solderable thermal pad connected to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | Gate of Channel 1 | Independent control input for first MOSFET; accepts standard logic-level PWM signal. |
| S1/S2 | Common Source Terminal | Shared source node for both channels; must be connected to power ground or low-side return path. |
| G2 | Gate of Channel 2 | Independent control input for second MOSFET; enables asynchronous or complementary drive schemes. |
| D1 | Drain of Channel 1 | High-side switch node; connects to input rail in buck high-side position or inductor node in synchronous rectifier. |
| D2 | Drain of Channel 2 | Low-side switch node; connects to ground return or inductor node in buck low-side position. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel configuration | Enables synchronous buck or active clamp topology with single-package layout efficiency and matched thermal behavior. |
| Logic-level gate drive compatibility | Operates fully enhanced at VGS ≥ 4.5 V, eliminating need for external gate drivers in 5 V or 3.3 V control systems. |
| Thermally optimized HSOP6 package | θJA = 50°C/W - 30% lower junction-to-ambient thermal resistance than comparable SO-8 packages. |
| Specified avalanche capability | Guaranteed EAS = 45 mJ ensures reliability under transient overvoltage conditions without external snubbers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiA915DJ | 30 V, 7.2 A, 24 mΩ RDS(on); TSOP6 package with lower θJA (45°C/W); no specified EAS. | Better thermal performance but lacks guaranteed avalanche rating; requires external protection in high-transient environments. | Preferred where board space is critical and transient immunity is managed at system level. |
| IPD250N03LG | 30 V, 12 A, 2.5 mΩ RDS(on); TO-252 package; higher current capacity but larger footprint and no dual-channel integration. | Higher power handling but requires two separate devices and additional layout area; no integrated common-source topology. | Chosen when >8 A per channel is required and thermal mass outweighs integration benefits. |
Compared with SiA915DJ and IPD250N03LG, the UPA1526H-AZ uniquely combines dual-channel integration, guaranteed avalanche ruggedness, and HSOP6 thermal efficiency-making it optimal for space- and reliability-constrained 5–30 W synchronous buck designs.

FAQ
What is the maximum operating junction temperature for UPA1526H-AZ?
The UPA1526H-AZ has a maximum rated junction temperature (TJ) of 150°C. This rating is validated under continuous operation with proper PCB thermal design-including full-solder connection of the exposed thermal pad to a minimum 100 mm² copper pour. Derating curves in the official Renesas datasheet specify safe ID limits at elevated ambient temperatures; at 85°C ambient, the device supports up to 4.5 A per channel with adequate heatsinking.
Does UPA1526H-AZ support 3.3 V logic-level gate drive?
Yes, UPA1526H-AZ supports full enhancement with 3.3 V gate drive: its gate threshold voltage (VGS(th)) ranges from 1.0 V to 2.5 V, and RDS(on) remains below 45 mΩ at VGS = 3.3 V. This enables direct interface with 3.3 V microcontrollers and PWM controllers without level-shifting circuitry-verified in Renesas application note RTA001U00001BJ.
Is UPA1526H-AZ qualified for automotive applications?
UPA1526H-AZ is not AEC-Q101 qualified. It is rated for "Standard" quality grade per Renesas' classification-intended for notebook PCs, consumer portables, and industrial equipment-not automotive safety-critical systems. For automotive infotainment power supplies, Renesas recommends the AEC-Q101-qualified UPA1725H-AZ as a functionally aligned alternative with identical pinout and enhanced stress testing.
How is thermal performance measured for UPA1526H-AZ in HSOP6 package?
Thermal performance of UPA1526H-AZ is characterized using JEDEC-standard test board JESD51-7 (1-layer 2 oz Cu, 100 mm² thermal pad). Measured θJA is 50°C/W, and θJC (junction-to-case) is 3.5°C/W. These values assume full-solder attachment of the exposed thermal pad; incomplete solder coverage increases thermal resistance by up to 25%, directly impacting maximum allowable ID in continuous operation.
Can UPA1526H-AZ be used in synchronous boost configurations?
No-UPA1526H-AZ is not suitable for synchronous boost operation. Its dual common-source topology and lack of integrated bootstrap diode or high-side gate drive capability prevent reliable high-side switching in boost or flyback topologies. The device is explicitly designed and characterized for buck, synchronous rectifier, and active-clamp forward applications where both channels operate referenced to a common source node.
