Product details
Overview
BZV85-C27,133 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 27 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, such as power supply feedback loops and overvoltage protection stages.
For engineers reviewing the BZV85-C27,133 datasheet, BZV85-C27,133 pinout, BZV85-C27,133 application, or BZV85-C27,133 equivalent, key selection criteria include its 27 V Zener voltage tolerance, differential resistance of 40 Ω at test current, temperature coefficient of +20.1 mV/K, junction-to-tie-point thermal resistance of 110 K/W, and suitability for PCB-mounted stabilization where lead thermal management is critical.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage across its terminals under varying load or input conditions. Its E24-standardized 27 V nominal Zener voltage (25.1–28.9 V range) and low dynamic impedance (40 Ω typical at IZ = 19 mA) enable accurate regulation in analog signal conditioning and power rail supervision.
Thermal performance is defined by two distinct operating conditions: 1.3 W dissipation with leads held at 55 °C at 4 mm from body, and 1 W with ambient at 25 °C and 10 mm lead length. Its junction temperature limit of 200 °C supports reliable operation in industrial-grade environments with moderate thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V nominal, 25.1–28.9 V min/max - defines regulated output voltage in shunt configuration |
| Differential Resistance (rdif) | 40 Ω typical at IZ = 19 mA - determines regulation accuracy under load variation |
| Temperature Coefficient (SZ) | +20.1 mV/K - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 1.3 W max with leads at 55 °C - sets maximum continuous DC power handling under controlled thermal mounting |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W at tp = 100 µs - enables transient overvoltage clamping without failure |
| Reverse Current (IR) | ≤ 0.05 µA at VR = 21.6 V - ensures minimal leakage in high-impedance bias networks |
| Forward Voltage (VF) | ≤ 1 V at IF = 50 mA - supports use as forward-biased clamp or indicator in dual-role designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4733A | 27 V nominal, ±5 % tolerance, 1 W Ptot, 35 Ω rdif, DO-41 package | Lower power rating limits sustained current to 37 mA vs. 48 mA for BZV85-C27,133 | Select when board space allows identical footprint but thermal margin is less constrained |
| BZX85C27 | 27 V nominal, ±5 %, 1.3 W Ptot, 45 Ω rdif, DO-41 package, higher IR (≤1 µA) | Slightly higher leakage reduces suitability in ultra-low-power sleep-mode circuits | Prefer for legacy designs where BZX85 series qualification is mandated |
Compared with 1N4733A and BZX85C27, the BZV85-C27,133 offers superior thermal robustness (1.3 W at 55 °C tie-point), tighter dynamic impedance control (40 Ω), and lower leakage (0.05 µA), making it optimal for high-reliability industrial regulators where thermal stability and long-term drift matter most.

FAQ
What is the maximum continuous Zener current for BZV85-C27,133 at 25 °C ambient?
At 25 °C ambient with 10 mm lead length, the maximum continuous Zener current is 48 mA, calculated from Ptot = 1 W and VZ = 27 V. This assumes no additional PCB copper heatsinking; with 1 cm² copper per lead, current can increase to 48.1 mA based on the 1.3 W rating at Ttp = 55 °C.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a specified +20.1 mV/K coefficient, the Zener voltage shifts +2.01 V over a 100 K rise. From 25 °C to 125 °C, VZ increases by ~2.0 V (to ~29 V), directly impacting regulation setpoint accuracy unless compensated in circuit design.
Can BZV85-C27,133 be used in series or parallel configurations for higher voltage or current handling?
Series connection is viable for higher voltage references but requires matched temperature coefficients to avoid thermal runaway; parallel use is not recommended due to unequal current sharing caused by manufacturing tolerances in VZ and rdif.
What is the significance of the "133" suffix in BZV85-C27,133?
The "133" denotes the specific ordering variant per Nexperia's packaging and reel configuration standard: it indicates tape-and-reel packaging with 3,000 units per reel, RoHS-compliant finish, and compliance with JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life).
