Product details
Overview
1N4741A,113 from Nexperia is a 11 V ±5 % Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 1000 mW total power dissipation and 8.4 mA working current at 11 V, used for low-voltage stabilization in linear power supplies and reference circuits.
For engineers reviewing the 1N4741A,113 datasheet, 1N4741A,113 pinout, 1N4741A,113 application, or 1N4741A,113 equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance (110 K/W), differential resistance (8 Ω), and real-world use cases in precision biasing and overvoltage clamping.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse-breakdown characteristics at 11 V nominal, designed for stable DC voltage regulation under fixed-current bias conditions. It exhibits 8 Ω typical differential resistance at 23 mA test current and maintains ≤5 % tolerance across temperature and aging.
The diode's thermal resistance from junction to tie-point is 110 K/W (lead length 4 mm), enabling reliable operation up to +200 °C junction temperature. Its forward voltage is ≤1.2 V at 200 mA, supporting dual-use as both regulator and clamp in low-power analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, ±5 % tolerance - ensures stable reference within ±0.55 V across production lots and operating temperatures. |
| Test Current (Itest) | 23 mA - defines the bias point where VZ and differential resistance are specified; matches typical shunt regulator operating point. |
| Differential Resistance (rdif) | 8 Ω - low dynamic impedance improves regulation accuracy against load current variations in feedback networks. |
| Total Power Dissipation (Ptot) | 1000 mW at Tamb = 50 °C - supports continuous operation in compact PCB layouts with moderate heatsinking. |
| Reverse Current (IR) | ≤5 µA at VR = 8.8 V - guarantees minimal leakage in high-impedance reference nodes and battery-backed circuits. |
| Forward Voltage (VF) | ≤1.2 V at IF = 200 mA - enables use as polarity-protected rectifier or crowbar element in auxiliary protection stages. |
| Junction Temperature Range | −65 °C to +200 °C - allows deployment in automotive engine compartments and industrial control enclosures without derating. |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with 2 leads: cathode marked by a visible band; body diameter 2.6 mm, lead spacing 25.4 mm, overall length 4.8 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation; carries full shunt current. |
| 2 (unmarked end) | Anode | Connected to ground or common return; establishes reference potential for breakdown voltage measurement. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or outdoor environments. |
| ±5 % Zener voltage tolerance | Reduces need for post-assembly trimming in cost-sensitive consumer and industrial power modules. |
| 1000 mW power rating | Supports direct replacement of legacy 1 W Zeners without board redesign or thermal pad expansion. |
| Low 8 Ω differential resistance | Minimizes output voltage variation under ±10 mA load transients in analog sensor excitation circuits. |
| −65 °C to +200 °C operating range | Enables single-part qualification across automotive, industrial, and aerospace sub-systems without variant SKUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4741A (ON Semiconductor) | Identical 11 V ±5 % rating, same SOD66 package, but 9 Ω rdif vs. Nexperia's 8 Ω; 1000 mW rating confirmed. | Validated in UL 60950-1 certified AC/DC adapters; slightly higher leakage (≤10 µA at 8.8 V). | Select when sourcing from ON Semi's authorized distribution chain; verify rdif impact on regulation error budget. |
| BZX79-C11 (Vishay) | Same 11 V ±5 %, SOD66, but 10 Ω rdif; Ptot = 1000 mW; Tj max = +175 °C (vs. +200 °C for Nexperia). | Commonly used in telecom line-card power rails; lower thermal margin restricts use in high-ambient industrial drives. | Choose for cost-sensitive telecom BOMs where ambient stays below 70 °C; avoid in engine-control units. |
Compared with 1N4741A,113, the ON Semiconductor variant offers near-identical performance with marginal rdif trade-off, while Vishay's BZX79-C11 sacrifices 25 °C junction headroom for broader global availability-critical for multi-source procurement strategies.

FAQ
What is the maximum reverse current at 8.8 V for 1N4741A,113?
The maximum reverse current (IR) is 5 µA at VR = 8.8 V, measured at Tj = 25 °C. This low leakage ensures minimal loading on high-impedance reference nodes and preserves accuracy in battery-powered sensor interfaces where quiescent current must stay below 10 µA.
Can 1N4741A,113 be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages, causing current hogging and thermal runaway when paralleled. For >1000 mW regulation, use a single higher-rated Zener or implement an active shunt regulator with external transistor and feedback.
Is the SOD66 package compatible with DO-41 footprint on PCBs?
Yes-the SOD66 outline is identical to JEDEC DO-41: 2.6 mm body diameter, 4.8 mm length, and 25.4 mm lead spacing. The marking band aligns with standard DO-41 cathode orientation, enabling drop-in replacement without layout changes or stencil adjustments.
What is the thermal resistance from junction to ambient for 1N4741A,113?
The datasheet specifies Rth(j-t) = 110 K/W from junction to tie-point (4 mm lead length), not junction-to-ambient. Ambient thermal resistance depends on PCB copper area and airflow; typical values range from 300–500 K/W in still air on 1 cm² copper, requiring derating above 50 °C ambient.
