Product details
Overview
BZV85-C24,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 24 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at Ttp = 55 °C, and 60 W non-repetitive peak reverse power handling. It serves as a precision voltage reference or shunt regulator in low-to-medium current stabilization circuits, commonly used in power supply feedback loops and overvoltage protection stages.
For engineers reviewing the BZV85-C24,133 datasheet, BZV85-C24,133 pinout, BZV85-C24,133 application, or BZV85-C24,133 equivalent, key selection criteria include its 22.8–25.6 V Zener voltage range, 30 Ω typical differential resistance at 5 mA test current, −0.05 µA max reverse leakage at 17 V, and thermal resistance of 110 K/W (junction-to-tie-point, 4 mm lead length).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across load variations and input fluctuations. Its temperature coefficient of +18.3 mV/K at 5 mA enables predictable drift compensation in analog references.
The device features axial-leaded, hermetically sealed glass construction for long-term reliability under thermal cycling and humidity exposure. Its 1.3 W power rating is validated under PCB mounting with 1 cm² copper per lead, and surge capability supports transient suppression up to 100 µs square-wave pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.8 V min to 25.6 V max at 5 mA - defines usable regulation window for 24 V nominal systems |
| Differential Resistance (rdif) | 30 Ω typical at 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤ 0.05 µA at VR = 17 V - ensures minimal quiescent power loss in standby operation |
| Total Power Dissipation (Ptot) | 1.3 W max at Ttp = 55 °C - sets continuous thermal limit with standard PCB heatsinking |
| Non-repetitive Peak Power (PZSM) | 60 W at tp = 100 µs - supports short-duration surge clamping without failure |
| Forward Voltage (VF) | ≤ 1 V at IF = 50 mA - enables use as forward-biased clamp or indicator in dual-role designs |
| Junction Temperature (Tj) | −65 °C to +200 °C - allows operation in extended industrial and automotive ambient ranges |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 110 K/W junction-to-tie-point Rth | Supports thermal design with discrete copper pour on FR-4 without forced air or heatsinks |
| 60 W pulse power rating | Clamps ESD transients (IEC 61000-4-2 Level 4) and inductive kickback without derating |
| −65 °C to +200 °C operating range | Validates use in under-hood automotive modules and industrial motor control enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4749A | 24 V nominal, ±5 %, 1 W Ptot, DO-41 package, but higher rdif (35 Ω typ) and no guaranteed 60 W surge rating | Limited to lower-power feedback loops; unsuitable for repetitive surge environments | Select when cost is primary constraint and thermal margin exceeds 20 % |
| BZX85C24 | 24 V nominal, ±5 %, 1.3 W Ptot, same SOD66 package, but higher IR (≤1 µA at 17 V) and wider VZ spread (22.0–26.0 V) | Acceptable for general-purpose regulation but less suitable for low-leakage precision references | Select when interchangeability with legacy BZX85 designs is required and leakage <0.1 µA is not critical |
Compared with 1N4749A and BZX85C24, BZV85-C24,133 offers superior surge robustness (60 W vs. unspecified), tighter leakage (0.05 µA), and lower dynamic impedance (30 Ω), making it preferred for industrial-grade feedback and protection where long-term parametric stability matters.

FAQ
What is the maximum continuous Zener current for BZV85-C24,133 at 25 °C ambient?
The maximum continuous Zener current is derived from Ptot = 1.3 W and VZ ≈ 24 V, yielding ~54 mA. However, derating is required above 25 °C ambient; at 55 °C tie-point temperature, the safe continuous current drops to ~43 mA to maintain junction temperature below 200 °C.
Can BZV85-C24,133 replace BZX85C24 in existing PCB layouts?
Yes - both use identical SOD66 (DO-41) package dimensions and axial lead configuration, with cathode band marking. Pin-for-pin replacement is mechanically and electrically valid, though BZV85-C24,133 offers lower leakage (0.05 µA vs. 1 µA) and tighter VZ spread (22.8–25.6 V vs. 22.0–26.0 V), improving regulation accuracy.
What is the thermal resistance from junction to ambient (Rth(j-a)) for this diode?
Rth(j-a) is 175 K/W when mounted on FR-4 with 10 mm lead length and no added copper area. With 1 cm² copper per lead (standard layout), effective Rth(j-a) improves to ~110 K/W, enabling 1.3 W dissipation at 55 °C tie-point temperature per datasheet condition [3].
Does BZV85-C24,133 meet automotive AEC-Q200 stress testing requirements?
No - while rated for −65 °C to +200 °C junction temperature and hermetically sealed, BZV85-C24,133 is not AEC-Q200 qualified. For automotive applications, Nexperia's AEC-Q200-qualified equivalents like PZM24NB2A (SOT23) or BZT52-B24 (SOD123) should be used instead.
