Product details
Overview
1N4735A,113 from Nexperia is a 6.2 V ±5 % Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 1000 mW total power dissipation and 500 mA maximum forward current, used for low-voltage stabilization in linear power supplies and reference circuits.
For engineers reviewing the 1N4735A,113 datasheet, 1N4735A,113 pinout, 1N4735A,113 application, or 1N4735A,113 equivalent, this page delivers verified Zener voltage, test current, differential resistance, reverse leakage, and thermal resistance - all critical for precision biasing, overvoltage clamping, and voltage reference design.
Technical Context
This device operates as a silicon planar Zener diode with sharp reverse breakdown at nominal 6.2 V when tested at 41 mA, exhibiting low dynamic impedance (2 Ω typical) and stable regulation under DC or pulsed conditions up to 1000 mW. Its axial-leaded SOD66 package ensures reliable thermal coupling to PCB traces or heatsinks via 4 mm lead length.
Designed for operation at junction temperatures from −65 °C to +200 °C, it maintains regulation integrity across industrial ambient ranges without derating below 50 °C ambient, supported by a junction-to-tie-point thermal resistance of 110 K/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal ±5 % - defines precise DC reference or clamp threshold in analog and power circuits |
| Test Current (Itest) | 41 mA - standardized bias point for measuring VZ and dynamic impedance |
| Differential Resistance (rdif) | 2 Ω typical at Itest - determines regulation stiffness and output voltage variation under load changes |
| Reverse Current (IR) | ≤10 µA at 4.96 V - ensures minimal standby leakage in high-impedance reference nodes |
| Total Power Dissipation (Ptot) | 1000 mW max at Tamb = 50 °C - sets absolute thermal limit for continuous DC operation |
| Forward Voltage (VF) | ≤1.2 V at IF = 200 mA - enables use as low-drop rectifier or polarity protection diode |
| Junction Temperature Range | −65 °C to +200 °C - supports deployment in extended-temperature industrial and automotive under-hood environments |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with cathode indicated by a single black band on the body; leads are tinned copper, suitable for wave or hand soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments |
| ±5 % voltage tolerance | Enables direct use in cost-sensitive applications without post-production trimming |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A-T | Same electrical specs; tape-and-reel packaging (3000 pcs/reel) vs. bulk (113 = bulk pack) | Automated SMT assembly compatibility; identical circuit behavior | Select for pick-and-place production; not suitable for manual prototyping without rework |
| BZX55C6V2 | Same 6.2 V ±5 %, but TO-92 plastic package; higher Rth(j-a) (500 K/W), lower Ptot (500 mW) | Limited to low-power, non-hermetic environments; unsuitable for >250 mW continuous use | Choose only for cost-sensitive consumer designs where hermeticity and 1 W rating are unnecessary |
Compared with 1N4735A,113, the 1N4735A-T offers identical regulation performance with automated handling benefits, while BZX55C6V2 trades hermetic reliability and power capability for lower cost and plastic-package convenience - making the original optimal for industrial-grade 1 W reference needs.

FAQ
What is the maximum continuous power dissipation for 1N4735A,113?
The 1N4735A,113 is rated for 1000 mW total power dissipation at an ambient temperature of 50 °C. Derating is required above this temperature at 11.1 mW/°C, reaching zero dissipation at 140 °C ambient, per its thermal resistance profile and absolute maximum ratings.
How does the 1N4735A,113 differ from the 1N4733A in practical design?
The 1N4735A,113 has a 6.2 V Zener voltage and 41 mA test current, while the 1N4733A is 5.1 V at 49 mA. Their differential resistances differ (2 Ω vs. 7 Ω), making the 1N4735A tighter for precision references; both share identical SOD66 packaging and 1000 mW rating.
Can 1N4735A,113 be used in AC signal clipping applications?
Yes - its symmetric forward conduction (≤1.2 V @ 200 mA) and sharp 6.2 V reverse breakdown enable bidirectional clipping. When back-to-back with another diode, it limits signal peaks to ±6.2 V, provided average power remains within 1000 mW and pulse duty cycle avoids thermal runaway.
Is the cathode marking consistent across all 1N47xxA devices?
Yes - all 1N4728A through 1N4749A devices use a single black band on the glass body to denote the cathode terminal, aligned with Pin 1 in the SOD66 outline. This marking is laser-permanent and visible under standard visual inspection without magnification.
