Product details
Overview
1N4734A,113 from Nexperia is a 5.6 V ±5 % Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 1000 mW total power dissipation and 45 mA test current, used for precision low-voltage stabilization in linear power supplies and reference circuits.
For engineers reviewing the 1N4734A,113 datasheet, 1N4734A,113 pinout, 1N4734A,113 application, or 1N4734A,113 equivalent, this part serves as a fixed-voltage shunt regulator with 5 Ω typical differential resistance, 10 µA max reverse leakage at 4.2 V, and thermal resistance of 110 K/W - critical for stable biasing and voltage reference design under varying load and ambient conditions.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 5.6 V reference across its terminals when biased above its knee current (≥2 mA). Its 5 Ω typical dynamic impedance ensures minimal output voltage variation under load changes up to 162 mA maximum working current.
Designed for operation at Tj = 25 °C with thermal equilibrium in still air, it delivers specified regulation within ±5 % tolerance and supports pulse operation per IEC 60134 limiting values, including 200 °C max junction temperature and 500 mA absolute maximum forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, ±5 % tolerance - defines precise shunt regulation point for 5 V-class reference designs |
| Test Current (Itest) | 45 mA - current at which VZ is measured; sets operating point for stable regulation |
| Differential Resistance (rdif) | 5 Ω typical - determines output impedance and load regulation sensitivity |
| Total Power Dissipation (Ptot) | 1000 mW at Tamb = 50 °C - limits continuous DC power handling without heatsinking |
| Reverse Current (IR) | ≤10 µA at VR = 4.2 V - ensures low quiescent leakage in standby or low-power reference nodes |
| Forward Voltage (VF) | ≤1.2 V at IF = 200 mA - defines anode-cathode drop during forward conduction, relevant for polarity protection |
| Junction Temperature Range | −65 °C to +200 °C - enables operation in extended industrial and automotive under-hood environments |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with 2 leads: cathode identified by a colored band; body diameter 2.6 mm, lead length 25.4 mm, and overall length ~40 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes shunt current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or harsh environments |
| ±5 % Zener voltage tolerance | Enables direct use in 5 V reference applications without trimming or external feedback |
| Low differential resistance (5 Ω) | Minimizes output voltage shift under load variations up to ±100 mA |
| 1000 mW power rating | Supports robust regulation in discrete linear regulators delivering up to ~180 mA at 5.6 V |
| −65 °C to +200 °C operating range | Validates suitability for industrial control modules and automotive body electronics |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A-TAP (ON Semiconductor) | Same 5.6 V ±5 %, 1000 mW rating, but packaged in DO-41 with different marking and traceability; 6 Ω rdif vs. 5 Ω | Identical functional role; minor rdif difference yields ~0.1 V higher load regulation error at 100 mA | Select when ON Semi's supply chain or lot traceability requirements apply; verify marking compatibility in automated assembly |
| BZX55-C5V6 (Vishay) | 5.6 V ±5 %, 500 mW Ptot, 10 Ω rdif, DO-35 package - lower power and higher impedance than 1N4734A,113 | Suitable only for low-current references (<20 mA); not interchangeable in 100+ mA regulation roles | Choose for space-constrained PCBs where 500 mW suffices and DO-35 footprint is preferred; derate power by 50 % for same thermal margin |
Compared with 1N4734A-TAP and BZX55-C5V6, the 1N4734A,113 offers superior power handling (1000 mW vs. 500 mW) and lowest dynamic impedance (5 Ω), making it optimal for medium-current analog references and linear regulator feedback where stability and low noise are critical.

FAQ
What is the maximum continuous reverse current the 1N4734A,113 can handle at 5.6 V?
The 1N4734A,113 is rated for a maximum working current (IZ) of 162 mA at its nominal Zener voltage of 5.6 V, as specified in Table 8 of the Nexperia datasheet. This value represents the highest DC current at which regulation remains within tolerance and thermal limits are maintained at Tamb = 50 °C.
Can the 1N4734A,113 be used in place of a 5.1 V Zener like the 1N4733A?
No - the 1N4734A,113 has a fixed 5.6 V nominal Zener voltage and is not a functional substitute for the 5.1 V 1N4733A. Substitution would shift reference or clamp thresholds by 0.5 V, potentially violating system voltage margins or causing incorrect regulation in feedback loops calibrated for 5.1 V.
Does the 1N4734A,113 require a series resistor in all applications?
Yes - a current-limiting resistor is mandatory to set the operating point between the minimum knee current (~2 mA) and maximum working current (162 mA). Without it, excessive current would cause thermal runaway or permanent damage, as the device lacks internal current regulation.
Is the SOD66 package of the 1N4734A,113 compatible with DO-41 footprints on PCBs?
Yes - the SOD66 package is the JEDEC-standardized designation for the DO-41 outline. Dimensions match exactly: 2.6 mm body diameter, 0.81 mm lead diameter, and standard axial lead spacing, enabling direct mechanical and soldering compatibility with legacy DO-41 land patterns.
