Nec B58944 Datasheet Free -

The IC works on a two-stage conversion principle:

If you cannot find the NEC B58944 datasheet at all, reply with the circuit function (switching, amplification, etc.) and we can suggest a modern replacement.



Once you download the free PDF, verify these critical specs:

| Parameter | Typical Range (depending on component type) | | --- | --- | | Polarity | NPN / PNP / N-Channel | | V(BR)CEO | 50V – 200V | | I(C) | 1A – 10A | | P(D) | 1W – 50W | | Package | TO-220, TO-247, or SOT-23 | nec b58944 datasheet Free

(Actual values depend on whether B58944 is a transistor, FET, or protection IC – confirm from the datasheet.)

The NEC B58944 is a specific electronic component (often a transistor, diode, or hybrid IC, depending on the series) manufactured by NEC (now part of Renesas Electronics). If you’re searching for a free datasheet for the B58944, you’ve likely hit a paywall or outdated link.

This guide explains exactly where to find the official B58944 datasheet PDF for free, without registration or credit card requirements. The IC works on a two-stage conversion principle:

If you are searching for a "NEC B58944" datasheet, you are likely hitting a dead end. The model number B58944 is most commonly associated with EPCOS/TDK (a partner/competitor to NEC in the semiconductor space), not NEC itself.

The search term "Free" adds unnecessary friction, as most component datasheets are legally free, but adding this keyword often funnels users into "pay-to-download" spam sites or questionable file-hosting lockers.


  • Wide Operating Voltage Range:
  • High Output Voltage (Peak-to-Peak):
  • Adjustable Output Frequency:
  • Built-in Oscillator:
  • Low Standby Current:
  • Simplified External Components:
  • Q: Is the NEC B58944 a transistor? A: Unlikely. NEC transistor part numbers follow the JEDEC standard (e.g., 2SA, 2SC, 2SB). "B58944" is too long and numerical for a standard transistor. Once you download the free PDF, verify these

    Q: Can I use a substitute if I don't have the datasheet? A: No. Never substitute an unknown IC. Without the datasheet, you don't know the logic voltage, pinout, or thermal limits. Substitution will almost certainly destroy the new part and potentially the rest of the board.

    Q: Why do some websites charge for this datasheet? A: They are scraping free databases and adding a paywall. They hope you are desperate. Do not pay them. If a site like "Datasheet-PDF-Bank" asks for $9.95, close the tab. It is a scam.

    Q: Could the "B58944" be a date code or lot number instead of a model? A: Possibly. Look at the chip again. Is there another line of text? Often, NEC printed the actual part number in a larger font (e.g., µPD78054) and used "B58944" as a manufacturing batch code. In this case, you need to search for the other number on the chip.
