概述

Description

BZX84C2V7LT1G is a fixed-voltage Zener diode in the BZX84 family. It provides a nominal 2.7 V breakdown in reverse bias and is used for low‑power voltage regulation, clamping, or as a reference in small circuits. The LT1G suffix denotes a specific RoHS/lot code variant from the vendor.
Key points:
- Zener voltage: ~2.7 V (tolerance around ±5% for the C grade)
- Package: SOT-23, lead-free variant (LT1G is a lot/processing code)
- Power rating: ~0.5 W at 25°C (derates with temperature)
- Typical test current: IZT ≈ 5 mA; ZZT ≈ 60–120 Ω (variant dependent)
- Applications: shunt regulator, voltage reference, or input/clamp protection in low-current designs
- Temp range: approx. −55°C to +125°C
Use by reverse-biasing with a current-limiting resistor to hold the voltage near 2.7 V.

Features

Here are the key features of BZX84C2V7LT1G:
- Zener diode with nominal Vz = 2.7 V
- Power rating: 500 mW (0.5 W)
- Package: SOT-23 (three leads), lead-free/ RoHS-compliant (LT1G)
- Zener tolerance: ±5% (C tolerance)
- Temperature range: -55°C to +125°C
- Suitable for small-signal regulation, reference, and overvoltage protection
- Izt (test current) and dynamic impedance in datasheet (typical values) for design reference
- Compact, inexpensive, widely available in surface-mount applications
Note: For exact electrical specs (Izt, Zzt, leakage, capacitance), refer to the datasheet.

Package

SOT-23 package (SC-70-3), a 3‑pin surface-mount Zener diode.

Pinout

- Pin count: 3 pins (SOT-23 package).
- Function: 2.7 V Zener diode (BZX84C2V7) used to clamp/regulate voltage in reverse bias.
- Pinout (typical): Pin 1 = Cathode, Pin 2 = Anode, Pin 3 = Not Connected (NC).

Manufacturer

Manufacturer: ROHM Semiconductor. ROHM is a Japanese multinational company that designs and manufactures semiconductors and electronic components (diodes, transistors, ICs, power devices) for automotive, consumer, and industrial applications.

Application

Applications:
- 2.7 V Zener reference in low-power analog/digital circuits (shunt regulator, ADC/comparator reference)
- Input/output protection and voltage clamping to ~2.7 V
- Simple surge/transient protection on low-voltage rails and signal lines
- Level shifting and protection for 2.7 V logic in microcontroller circuits
(Contains typical uses for BZX84C2V7LT1G.)
