Vhm 314 Datasheet [extra Quality] < 2026 Update >
A standard Vhm 314 comes in a or TO-220-7 derivative package. Understanding the pinout is essential for PCB layout:
| Pin # | Name | Function | | :--- | :--- | :--- | | 1 | Vcc | Main power supply (8-36V). Bypass with 100µF + 0.1µF ceramic. | | 2 | OUT | Load output (connect to solenoid, LED, or resistive load). | | 3 | GND | Power ground. Must be isolated from signal ground. | | 4 | IN+ (Analog) | Non-inverting analog setpoint (0–5V = 0–3.14A). | | 5 | IN- (PWM) | Digital PWM input (20kHz recommended for silent operation). | | 6 | DIAG | Open-drain fault indicator (active low for overtemp/short circuit). | | 7 | REF | Internal 2.5V reference output (max 1mA). | | 8 | ISENSE | Current monitor output (0.5V per Ampere). | | 9-15 | NC | No connect (used for thermal conduction to PCB). | Vhm 314 Datasheet
This section defines the physical and electrical limits of the VHM 314. Exceeding these values can lead to immediate failure or reduced lifespan. A standard Vhm 314 comes in a or TO-220-7 derivative package
: The datasheet provides the exact composition of VHM 314. This is crucial for understanding its properties, such as hardness, density, and magnetic properties. For instance, the percentage of tungsten carbide (WC) versus cobalt (Co) or other binders can significantly affect the material's performance in different applications. | | 2 | OUT | Load output
