Used with a thyristor/SCR: when input exceeds ~10.6 V, the Zener conducts, triggering the SCR to short the supply and blow a fuse.
| Device | VZ (V) | PD (W) | Package | Key Difference | |--------|--------|--------|---------|----------------| | | 10 | 0.5 / 1 | SOD-123FL / SMA | General purpose, good surge | | BZX84C10 | 10 | 0.35 | SOT-23 | Lower power, smaller | | 1SMA5919BT3G | 10 | 1.5 | SMA | Higher power, better surge | | MMSZ5250B | 10 | 0.5 | SOD-123 | Similar, but different tolerance |
On surface-mount components, the marking "C10" may be printed on the cathode side or the top face. The band or marking line on the device indicates the (negative side).
The is a surface-mount Zener diode designed for precision voltage clamping and regulation. The "C10PH" designation typically follows manufacturer-specific coding (commonly associated with General Semiconductor (Vishay) or equivalent brands like STMicroelectronics or Diodes Inc. in the SOD-123FL or SMA package). diodo zener c10ph
The C10PH operates on the principle of the (and Avalanche breakdown at higher voltages).
Most commonly, components marked with in power electronics are 10 Volt Zener diodes . The "PH" often refers to the package type or a specific manufacturer's series code (such as a SOD-323 or similar "PH" package).
The C10PH is versatile and found in various consumer and industrial electronics: Used with a thyristor/SCR: when input exceeds ~10
The junction is passivated with glass or planar oxide to ensure low leakage and high stability over time.
The simplest use: a current-limiting resistor + C10PH across the load. Example: 15 V unregulated input → 10 V regulated output at up to 40 mA (assuming 500 mW device).

While specific datasheets vary by manufacturer (such as MCC, ON Semiconductor, or Vishay), the typical specifications for a C10-type Zener diode are as follows:
The small package makes it ideal for (smartphones, wearables, IoT sensors).
