Specs side by side
2 parts compared · 18 differing specs across 18 total parameters.
| Parameter | ||
|---|---|---|
| Operating temperature | -65°C ~ 200°C | - |
| Supply voltage | - | Same nominal, tighter window: the grade buys certainty, not headroom. |
| Voltage - Zener (nom) | 5.1 V | - |
| Memory & Peripherals | - | Where it matters: reference-adjacent clamping, comparator thresholds and any rail whose margin was computed at the tight window. |
| Case | DO-204AL, DO-41, Axial | DO-41 |
| Package | Bulk | - |
| Compatibility Level | - | 100% Drop-in (Zero Code Change) |
| Core & Architecture | - | The precision grades of the same voltage: C at 2 percent and D at 1 percent tolerance against the 5 percent of the common A suffix - exact drop-ins where accuracy was the design point. |
| Current - Reverse Leakage @ Vr | 10 µA @ 1 V | - |
| Firmware Notes | - | Direction rule: precision upward is always free; dropping from a graded part to the 10 percent no-suffix member is the substitution that quietly re-opens a margin someone calculated. |
| Hardware Notes | - | Identical DO-41 body. |
| Impedance (max) | 7 Ohms | - |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Mounting | Through Hole | - |
| Power - Max | 1 W | - |
| Reference Part | - | 1N4733A |
| Sourcing Advantage | - | Stocked by grade; order with the suffix the schematic asked for. |
| Tolerance | ±5% | - |
