HTV371 is a concise identifier; below is a polished, general-purpose piece of content suitable for use in documentation, a product page, or an academic summary. Adjust tone or length if you want marketing, technical, or educational variants.
If your SMPS or ballast has failed, the HTV371 is a prime suspect. Because it handles high voltage and heat, it is subject to:
Assuming access to a generic manufacturer datasheet for a transistor labeled HTV371, the following specifications are critical for design and replacement:
| Parameter | Symbol | Value | Unit | | :--- | :--- | :--- | :--- | | Collector-Base Voltage | Vcbo | 700 | V | | Collector-Emitter Voltage | Vceo | 450 | V | | Emitter-Base Voltage | Vebo | 7 | V | | Collector Current (Continuous) | Ic | 2 | A | | Collector Current (Peak) | Ic(pulse) | 4 | A | | Base Current | Ib | 0.5 | A | | Power Dissipation (Tc=25°C) | Pd | 30 | W | | DC Current Gain (hFE) | @ Ic=0.5A | 15 - 60 | - | | Transition Frequency | ft | 4 - 8 | MHz | htv371
Interpretation: The HTV371 is a slow-to-medium speed transistor (4-8 MHz), meaning it is suitable for 50/60 Hz mains switching and low-frequency inverters, but not for high-frequency RF circuits (above 30 MHz).
In the rapidly evolving world of electronic components, part numbers often serve as the only identifier for critical pieces of hardware. One such identifier that has been generating significant query volume in technical forums and component sourcing databases is HTV371.
While the alphanumeric code "HTV371" might appear cryptic at first glance, it typically points to a specific electronic component—most likely a high-voltage transistor, a voltage regulator, or a specialized IC (Integrated Circuit) used in power management or RF amplification. HTV371 is a concise identifier; below is a
Whether you are an electronics engineer, a repair technician, or a hobbyist working on a restoration project, understanding the datasheet, pinout, equivalents, and common failure modes of the HTV371 is essential. This article provides a deep dive into everything you need to know about the HTV371.
In low-power DC-AC inverters (100W-200W range), the HTV371 can be used in a push-pull configuration to generate 110V or 220V AC from a 12V battery.
If you are using the HTV371 in a new design (retro style), here is a basic 100W inverter driver stage: Design Tips: The HTV371 is generally classified as
+12V DC ----[Primary Coil]----+---- Collector (Pin 2) HTV371

GND (0V) ---------------------+---- Emitter (Pin 3) HTV371
Design Tips:
The HTV371 is generally classified as a NPN Silicon Power Transistor or a High-Voltage Switching Transistor. Depending on the manufacturer (often associated with brands like Toshiba, STMicroelectronics, or a specific Asian semiconductor house), the HTV371 is designed to operate in environments requiring high breakdown voltages and moderate switching speeds.
