Product details
Overview
UPA1572BH(1)-AZ from NEC is an N-channel power MOSFET array with four integrated circuits in a 10-pin SIP package, designed for solenoid, motor, and lamp driver applications. It supports 4 V gate drive, delivers ±2.0 A DC drain current per channel, exhibits RDS(on) ≤ 0.6 Ω at VGS = 10 V, and operates up to 150 °C channel temperature.
For engineers reviewing the UPA1572BH(1)-AZ datasheet, UPA1572BH(1)-AZ pinout, UPA1572BH(1)-AZ application, or UPA1572BH(1)-AZ equivalent, key selection criteria include its low-threshold 4 V drive capability, built-in gate protection diodes, avalanche-rated operation (IAS = 5.0 A), and thermal derating behavior across ambient and case temperatures.
Technical Context
The UPA1572BH(1)-AZ integrates four independent N-channel enhancement-mode MOSFETs sharing common source terminals (pins 1 and 10) and isolated gate/drain connections. Each channel features internal gate protection diodes against ESD, and is rated for single-pulse avalanche energy of 0.1 mJ under defined test conditions (VDD = 30 V, RG = 25 Ω, L = 100 µH).
Its switching performance includes td(on) = 30 ns, tr = 200 ns, td(off) = 100 ns, and tf = 160 ns at VDD = 30 V, ID = 1.0 A, and RG = 10 Ω. Input capacitance Ciss is 110 pF typical, supporting fast switching while maintaining gate drive efficiency at low VGS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum drain-source blocking voltage per channel; defines safe operating range in inductive load switching. |
| RDS(on) @ VGS = 4 V | 0.8 Ω max - Enables direct logic-level drive from 3.3 V/5 V microcontrollers without level-shifting circuitry. |
| ID (DC) | ±2.0 A/unit - Continuous current rating per channel at TA = 25 °C; derates to ~1.0 A at 100 °C ambient. |
| QG | 5.4 nC - Total gate charge determines required gate driver peak current and switching loss in PWM applications. |
| Ciss | 110 pF typ - Low input capacitance reduces gate drive power and improves high-frequency switching efficiency. |
| TCH max | 150 °C - Maximum allowable channel temperature; sets thermal design margin for heatsink sizing and PCB copper area. |
| EAS | 0.1 mJ - Single-pulse avalanche energy rating enables robustness against inductive kickback in relay/solenoid drivers. |
Pinout & Package
UPA1572BH(1)-AZ uses a 10-pin Single In-line Package (SIP) with full mold construction. Pin 1 and Pin 10 are common source terminals; Pins 2, 4, 6, and 8 are individual gate inputs; Pins 3, 5, 7, and 9 are individual drain outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | Source (common) | Shared low-side return path for all four channels; must be connected to system ground or low-side rail. |
| 2, 4, 6, 8 | Gate | Independent control inputs; each accepts 0–20 V gate drive; built-in ESD protection diodes to VSS and VDD. |
| 3, 5, 7, 9 | Drain | Individual high-side switch outputs; each drives one solenoid/motor winding/lamp load independently. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 4 V, enabling direct interface with 3.3 V/5 V MCUs without external level shifters. |
| Integrated gate protection | Built-in gate-to-source diodes suppress static discharge during handling and prevent gate oxide damage. |
| Four-channel integration | Reduces board space and component count versus discrete MOSFET solutions for multi-load control systems. |
| Avalanche-rated operation | Rated for 5.0 A single-pulse avalanche current and 0.1 mJ energy, enhancing reliability in inductive switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS27082LDR | Single-channel smart high-side switch with current limiting and fault reporting; not pin-compatible; no avalanche rating. | Designed for diagnostic-aware systems requiring load monitoring; lacks multi-channel integration. | Choose when system-level diagnostics outweigh cost and board space savings of integrated quad-switch architecture. |
| STP16NF06L | Discrete TO-220 N-channel MOSFET; RDS(on) = 0.18 Ω @ 10 V but requires four separate devices, gate drivers, and layout area. | Higher board area and BOM count; better thermal dissipation per channel but no shared source convenience. | Choose when higher current (>2 A) or lower RDS(on) per channel is mandatory and layout space permits discrete implementation. |
Compared with TPS27082LDR and STP16NF06L, the UPA1572BH(1)-AZ uniquely balances quad-channel integration, 4 V logic compatibility, and specified avalanche ruggedness-making it optimal for space-constrained, inductive-load applications where discrete complexity or smart-switch diagnostics are unnecessary.

FAQ
What is the maximum gate-to-source voltage rating for UPA1572BH(1)-AZ?
The UPA1572BH(1)-AZ has a maximum AC gate-to-source voltage rating of ±20 V. Exceeding this voltage risks permanent gate oxide damage. The datasheet explicitly recommends adding external gate protection circuits if transient overvoltage exceeding ±20 V is possible in the application. This specification applies directly to the UPA1572BH(1)-AZ and is verified in the Absolute Maximum Ratings table.
Can UPA1572BH(1)-AZ drive a 12 V solenoid drawing 1.8 A continuously?
Yes, the UPA1572BH(1)-AZ supports ±2.0 A DC drain current per channel at TA = 25 °C, and its RDS(on) ≤ 0.6 Ω at VGS = 10 V results in <1.1 W conduction loss at 1.8 A. With proper PCB copper area and ambient temperature below 70 °C, the UPA1572BH(1)-AZ can reliably drive such a solenoid. Thermal derating curves confirm viability for this use case.
Does UPA1572BH(1)-AZ include body diodes, and what is their forward voltage?
Yes, the UPA1572BH(1)-AZ includes intrinsic body diodes between source and drain in each channel. Its body diode forward voltage VF(S-D) is 1.0 V at ISD = 2.0 A and VGS = 0, as measured per the Electrical Characteristics table. This allows safe freewheeling current path during inductive turn-off without requiring external diodes.
What is the total gate charge QG of UPA1572BH(1)-AZ, and why does it matter?
The UPA1572BH(1)-AZ has a total gate charge QG of 5.4 nC at VGS = 10 V and ID = 2.0 A. This value determines the minimum peak gate drive current needed for fast switching and directly impacts switching losses. For example, driving QG in 50 ns requires ≥108 mA peak current-critical for selecting appropriate gate drivers in high-frequency PWM designs using the UPA1572BH(1)-AZ.
Is UPA1572BH(1)-AZ suitable for use in medical equipment?
The UPA1572BH(1)-AZ carries NEC's "Standard" quality grade, which covers medical equipment not specifically designed for life support. Its 150 °C channel temperature rating, avalanche energy rating (EAS = 0.1 mJ), and proven reliability in motor/solenoid control make it suitable for non-critical medical devices like infusion pumps and diagnostic analyzers-as confirmed in NEC's quality grade documentation referenced in the datasheet.
