BZX84C15VLFHT116

BZX84C15VLFHT116 is a 15-volt Zener diode from the BZX84C family, in an SOT-23 package. It is used for low-power voltage regulation and input protection by clamping a supply rail to about 15 V.
Key points:
- Voltage: nominal Vz ≈ 15 V at the specified test current; tolerance typically ±5%.
- Power: about 0.5 W maximum rating (derates with temperature).
- Package: SOT-23; cathode and anode pins arranged to allow reverse bias in normal operation.
- Suffix meaning: LF indicates lead-free packaging; HT116 is a manufacturing/date/lot code, not a voltage spec.
- Applications: simple shunt regulator/reference, rail clamping, overvoltage protection in low-power circuits.
Notes:
- Always verify exact electrical characteristics (Iz test current, dynamic impedance, max reverse voltage) in the specific datasheet for the LFHT116 lot, as variants exist across manufacturers.

Equivalent 15 V SOT-23 Zener diodes:
- BZX84C15 (various manufacturers: Nexperia, Diodes Inc., ON Semiconductor)
- BZT52C15 / BZT52H-C15 (SOT/SOD variants)
- BZX84C15LT1G (Diodes Inc. reel/tape version)
- BZV55C15 (if through‑hole package acceptable)
Always verify Vz, test current, power dissipation and tolerance before substituting.

- 15 V nominal Zener diode (BZX84C series)
- 0.5 W (500 mW) power dissipation
- SOT-23 surface-mount package (three-terminal)
- Unidirectional Zener for regulation and clamping
- Tolerance typically ±5%
- Wide operating temperature: -55°C to +125°C
- Lead-free, RoHS compliant
- Suitable for compact voltage reference, regulator, and surge/clamp applications
Note: “LF” in the suffix usually denotes lead-free/ RoHS-compliant packaging; “HT116” is a date/lot code.

Pin count: 2 (anode and cathode/SMD pads).
Function: 15 V Zener diode (reverse breakdown ~15 V) used for voltage regulation, reference or transient/clamping/protection in low‑power SMD circuits.

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Incorporated is a publicly traded (Nasdaq: DIOD) multinational semiconductor company that designs, manufactures and supplies discrete, logic, analog and power-management semiconductor components (including diodes, transistors, rectifiers, voltage regulators and ICs) for consumer, industrial, computing and communications applications.

BZX84C15V is a 15 V Zener diode (SOT-23, about 0.5 W). Typical applications include:
- Low-power voltage regulation and as a simple shunt reference around 15 V
- Overvoltage protection and clamping of DC rails and I/O lines
- Surge/transient suppression in automotive/industrial 12–24 V systems
- Input protection for microcontrollers, op-amps, and ADCs
- ESD/overvoltage protection on data and control interface lines
These make it suitable for compact, low-current voltage regulation and protection in mixed-signal circuits.

I don’t have the manufacturer for BZX84C15VLFHT116. Many BZX84C15 variants are supplied in the SOT‑23 (TO‑236AB) SMD package, but some vendors use SOD‑323/SOD‑523. Please provide the manufacturer or datasheet link for the exact package.
