The SL5225‑SL5262 series are silicon planar Zener diodes offered in a MiniMELF package, with an optional DO‑35 case (type designations 1N5225‑1N5262). Standard Zener voltage tolerance is 20%; suffix “A” provides +10% tolerance and suffix “B” provides +5% tolerance. These devices are supplied taped for automated handling.
Key electrical ratings include a maximum power dissipation of 500 mW at a junction temperature of 75 °C, a maximum junction temperature of 175 °C, and a storage temperature range of –65 °C to +175 °C. The thermal resistance (junction‑to‑ambient) is 0.3 °C/W and forward voltage is approximately 1 V at 200 mA. Weight is about 0.05 g per device.
| Power Dissipation (Tj = 75 °C) | 500 mW |
|---|---|
| Maximum Junction Temperature | 175 °C |
| Storage Temperature Range | -65 °C to +175 °C |
| Thermal Resistance (RθJA) | 0.3 °C/W |
| Forward Voltage (200 mA) | 1 V |
| Weight (per device) | 0.05 g |
| Package Type | MiniMELF (also available in DO‑35) |
| Zener Voltage Tolerance | Standard 20 %; suffix A +10 %; suffix B +5 % |
Standard tolerance is 20 %; adding suffix “A” gives +10 % tolerance and suffix “B” gives +5 % tolerance.
They are supplied in a MiniMELF case and also in a DO‑35 case with type designations 1N5225‑1N5262.
The diodes can dissipate up to 500 mW when the junction temperature is 75 °C.
They can be stored from –65 °C up to +175 °C.
