Product details
Overview
1N4736A,113 from Nexperia is a 6.8 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 precision low-voltage stabilization in linear power supplies and reference circuits.
For engineers reviewing the 1N4736A,113 datasheet, 1N4736A,113 pinout, 1N4736A,113 application, or 1N4736A,113 equivalent, this page delivers verified electrical parameters, cathode/anode terminal mapping, thermal resistance (110 K/W), differential resistance (3.5 Ω), and real-world use cases in analog voltage references and overvoltage protection.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 6.8 V reference across a 4 mA working current (IZ), with low dynamic impedance (3.5 Ω) ensuring minimal output voltage variation under load changes. Its 1000 mW power rating enables robust operation in discrete regulator stages without active cooling.
The device exhibits a forward voltage of ≤1.2 V at 200 mA and junction temperature range from −65 °C to +200 °C, supporting reliability in industrial ambient conditions. Thermal resistance from junction to tie-point is 110 K/W (lead length 4 mm), defining its steady-state derating behavior above Tamb = 50 °C.
Key Specifications

| Test Current (Itest) | 4 mA - operating point where VZ and dynamic impedance are specified |
| Differential Resistance (rdif) | 3.5 Ω - low impedance ensures <10 mV output shift per 35 mA load change |
| Total Power Dissipation (Ptot) | 1000 mW - supports continuous regulation in compact PCB layouts without heatsinking |
| Forward Voltage (VF) | ≤1.2 V at IF = 200 mA - enables use as clamp or polarity protection diode |
| Junction Temperature Range | −65 °C to +200 °C - validated for extended thermal cycling in automotive and industrial control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4736A-TAP (ON Semiconductor) | Same 6.8 V ±5 %, 1000 mW rating; DO-41 package; tighter test current spec (4.0 mA vs 4 mA typical) | Identical functional role; minor packaging marking variance (TAP vs ,113) | Select when sourcing from ON Semi distribution channels or requiring alternate tape-and-reel packaging |
| BZX55C6V8 (Vishay) | 6.8 V ±5 %, 500 mW Ptot; same DO-41 outline but lower power rating and higher rdif (5 Ω) | Suitable only for low-current (<20 mA) reference or clamping; not for 100 mA+ shunt loads | Choose only if thermal constraints limit power dissipation to ≤500 mW and dynamic impedance <5 Ω is acceptable |
Compared with 1N4736A,113, the ON Semiconductor 1N4736A-TAP offers identical electrical performance and mechanical compatibility, while the Vishay BZX55C6V8 trades 500 mW power headroom and higher impedance for cost-sensitive, low-power designs.

FAQ
What is the maximum continuous reverse current the 1N4736A,113 can handle at 25 °C?
The 1N4736A,113 is rated for a working current (IZ) of 4 mA at nominal Zener voltage, but its absolute maximum non-repetitive peak reverse current (IZSM) is 660 mA. Continuous operation is limited by power dissipation: at 6.8 V, maximum sustainable IZ is ~147 mA (1000 mW ÷ 6.8 V), assuming adequate thermal management and ambient temperature ≤50 °C.
How does the 1N4736A,113 differ from the 1N4736A-TAP in practical design use?
The 1N4736A,113 (Nexperia) and 1N4736A-TAP (ON Semiconductor) share identical Zener voltage (6.8 V ±5 %), power rating (1000 mW), package (DO-41/SOD66), and key electrical specs. The difference lies solely in manufacturer branding, packaging format (,113 = bulk/ammopack; TAP = tape-and-reel), and minor test current tolerance-both are functionally interchangeable in all circuit roles.
Can the 1N4736A,113 be used in surface-mount designs?
No-the 1N4736A,113 uses an axial-leaded SOD66 (DO-41) glass package designed exclusively for through-hole mounting. It lacks solder pads or land patterns compatible with reflow or wave soldering. For SMT equivalents, consider Nexperia's BZX384-B6V8 (SOD-323, 250 mW) or PZM6.8NB (SOT-23, 300 mW), which differ in power rating and thermal performance.
What is the thermal resistance from junction to ambient for the 1N4736A,113 in free air?
The datasheet specifies Rth(j-t) = 110 K/W from junction to tie-point (4 mm lead length), not junction-to-ambient. In still air with standard 4 mm lead length, measured junction-to-ambient thermal resistance is approximately 500 K/W. Derating curves show 1000 mW is only sustainable up to Tamb = 50 °C; above that, linear derating applies at 8.3 mW/°C.
