BAS116LPH4-7B

Introduction: BAS116LPH4-7B is a small-signal NPN transistor used for fast switching and low-power amplification in surface-mount (SMT) circuits. The BAS116 family is valued for high current gain and low leakage, while the LPH4-7B suffix denotes a specific package variant and production code. Exact electrical specs (Vce, Ic, power rating) depend on the lot and package; always consult the manufacturer’s datasheet for the BAS116LPH4-7B variant. Typical uses include driving small loads (LEDs, relays) or buffering signals in digital or analog circuits. In design, provide appropriate base biasing, respect maximum ratings, and consider thermal limits. If in doubt, verify with the official datasheet from the supplier to confirm package, ratings, and pinout for this exact part variant.

General-purpose 100 V/150 mA switching diodes in the same SOD-523 footprint are direct substitutes for BAS116LPH4-7B. Common equivalents include:
• 1N4148 (DO-35) or its SMD versions LL4148/LL4148W (SOD-523)
• 1N914 (and SMD LL914)
• BAS116 from Infineon, Nexperia or Vishay (other reel/package codes)

BAS116LPH4-7B features (typical for BAS116 family):
- Single fast-switching silicon diode
- PH package (SMD), lead-free, RoHS compliant
- High switching speed with short reverse-recovery time
- Forward current rating around 150–200 mA
- Reverse voltage rating around 75–100 V
- Forward voltage drop typically 0.7–1.0 V at rated IF
- Low reverse leakage; good for protection and clamping
- Wide operating temperature range (typically -55°C to +125°C)
- Suitable for general-purpose rectification, demodulation, clipping, and protection in compact SMT designs
Note: exact VRRM, IF, and Vf values can vary slightly by lot; consult the datasheet for precise specs.

- Pin count: 3 pins (SOT-23 package).
- Function: Dual switching/signal diodes in one package (two small-signal diodes, common-cathode configuration) used for high-speed switching, level clamping and transient/protection.
- Typical pin assignment: Pin 1 = Anode 1, Pin 2 = Common cathode, Pin 3 = Anode 2.
