Product details
Overview
TDZ5V1J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and transient suppression in low-power circuits. It delivers a nominal Zener voltage of 5.1 V at 5 mA, with differential resistance ≤480 Ω, total power dissipation up to 500 mW, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ5V1J,115 datasheet, TDZ5V1J,115 pinout, TDZ5V1J,115 application, or TDZ5V1J,115 equivalent, key selection criteria include Zener voltage tolerance (±2%), temperature coefficient (−2.7 mV/K), low capacitance (300 pF), and non-repetitive peak reverse power capability (180 W).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its −2.7 mV/K temperature coefficient ensures predictable drift across −55 °C to +150 °C ambient range, and its 480 Ω typical differential resistance supports tight regulation in feedback paths.
The device uses a planar epitaxial construction optimized for low leakage and fast response to voltage transients. Mounting on FR4 PCB with 16 mm² cathode pad yields Rth(j-a) = 250 K/W and Rth(j-sp) = 25 K/W, enabling reliable thermal performance in space-constrained SMT layouts.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 5.00–5.20 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Differential Resistance (rdif) | ≤480 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Reverse Current (IR) | ≤2 µA at VR = 3 V - guarantees low standby power loss in always-on regulation circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V1 | Same 5.1 V nominal Zener voltage but higher differential resistance (600 Ω) and no AEC-Q101 qualification | Targeted at commercial-grade consumer electronics, not automotive or industrial environments | Select when cost sensitivity outweighs automotive qualification and tighter regulation requirements |
| MMSZ5231B | 5.1 V rating with ±5% tolerance (vs. ±2% for TDZ5V1J), 1000 Ω rdif, and 350 mW Ptot | Used in general-purpose power supply feedback loops where precision and surge margin are secondary | Choose for legacy designs requiring SOD-123 footprint compatibility and broader vendor availability |
Compared with BZX584-C5V1 and MMSZ5231B, TDZ5V1J,115 offers superior voltage accuracy, lower dynamic impedance, higher surge robustness, and automotive-grade reliability-making it optimal for safety-critical and thermally demanding applications where regulation stability is non-negotiable.

FAQ
What is the maximum continuous forward current rating for TDZ5V1J,115?
The absolute maximum forward current is 250 mA per Table 5 of the datasheet. However, sustained forward conduction is not the intended operating mode; the device is optimized for reverse-bias Zener regulation. Forward voltage remains ≤1.1 V at 100 mA, but thermal limits require derating above 100 mA in ambient >25 °C.
Can TDZ5V1J,115 be used as a substitute for a 5.0 V Zener in an existing design?
Yes, with verification of tolerance impact: TDZ5V1J specifies 5.00–5.20 V (±2%) at 5 mA, whereas generic 5.0 V Zeners often have ±5% tolerance. Its lower differential resistance (480 Ω vs. typical 1000 Ω) improves regulation, but layout must accommodate SOD323F's smaller pad geometry and thermal pad requirements.
How does the −2.7 mV/K temperature coefficient affect circuit performance at 125 °C?
From 25 °C to 125 °C, ΔT = 100 K, so VZ shift ≈ −2.7 mV/K × 100 K = −0.27 V. Thus, nominal 5.10 V becomes ~4.83 V. This predictable drift enables compensation in analog front-ends, but uncorrected use in precision references requires derating or calibration.
Is reflow soldering the only recommended assembly method for TDZ5V1J,115?
Yes-the datasheet explicitly states "Reflow soldering is the only recommended soldering method" (Section 11). Wave or hand soldering risks thermal damage due to the SOD323F package's low thermal mass and sensitivity to localized overheating; JEDEC J-STD-020-compliant reflow profiles must be followed.
