Product details
Overview
TDZ3V0J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation at 3.0 V nominal Zener voltage (2.94–3.06 V), with 500 mW total power dissipation, 500 Ω typical differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use. It serves as a stable reference or clamp in low-power analog circuits, such as sensor biasing and microcontroller reset supervision.
For engineers reviewing the TDZ3V0J,115 datasheet, TDZ3V0J,115 pinout, TDZ3V0J,115 application, or TDZ3V0J,115 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 K/W junction-to-ambient), reverse current limit (10 µA at VR = 2.4 V), cathode-anode polarity marking, and compatibility with reflow soldering on FR4 PCBs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under controlled current conditions. Its temperature coefficient of −3.5 mV/K ensures predictable drift over ambient range (−55 °C to +150 °C), and its low capacitance (425 pF at 1 MHz, VR = 0 V) supports high-frequency noise suppression without signal distortion.
The device delivers non-repetitive peak reverse power dissipation up to 180 W for pulses ≤300 µs (duty cycle ≤2%), enabling transient overvoltage clamping in ESD-sensitive interfaces. Its 25 K/W junction-to-solder-point thermal resistance facilitates effective heat transfer when mounted on a 16 mm² tin-plated copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.94–3.06 V at IZ = 5 mA - tight ±2% tolerance enables accurate 3.0 V reference generation |
| Differential Resistance (rdif) | 500 Ω max at IZ = 5 mA - low impedance maintains regulation stability under load variation |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - defines continuous DC power handling on standard FR4 PCB |
| Reverse Current (IR) | 10 µA max at VR = 2.4 V - ensures minimal leakage in standby or low-current bias networks |
| Thermal Resistance (Rth(j-a)) | 250 K/W - determines junction temperature rise above ambient under steady-state operation |
| Non-repetitive Peak Power (PZSM) | 180 W for tp ≤ 300 µs - supports robust transient surge suppression in automotive ECUs |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-C3V0,115 | Same 3.0 V nominal Zener voltage but ±5% tolerance (2.85–3.15 V); 300 mW Ptot; SOD323 package | Lacks AEC-Q101 qualification; higher voltage tolerance reduces accuracy in precision biasing | Select when cost sensitivity outweighs automotive qualification and tighter regulation needs |
| MMSZ3V0T1G | 3.0 V nominal, ±5% tolerance; 500 mW Ptot; SOD-123 package (larger footprint: 3.7 × 1.6 mm) | Higher thermal resistance (300 K/W) limits power handling on dense layouts; no AEC-Q101 certification | Choose only if legacy SOD-123 footprint compatibility is required and automotive compliance is not mandated |
Compared with TDZ3V0J,115, BZX384-C3V0,115 trades automotive reliability and voltage precision for lower cost, while MMSZ3V0T1G sacrifices board area efficiency and qualification for broader distributor availability - neither matches the combined AEC-Q101, ±2% VZ, and SOD323F space optimization of the TDZ3V0J,115.

FAQ
What is the maximum continuous forward current for TDZ3V0J,115?
The absolute maximum forward current is 250 mA per Table 5 of the datasheet. However, forward conduction is not its intended operating mode; it is specified only for handling brief forward surges during circuit transients or test conditions - sustained forward bias risks thermal overstress and parameter shift.
Can TDZ3V0J,115 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and manufacturing variations that cause current hogging when paralleled. Even matched units will thermally diverge, leading to premature failure of one device. For >500 mW regulation, use a single higher-rated Zener or an active shunt regulator.
Is the SOD323F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD323F package complies with JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak temperatures up to 260 °C for ≤30 seconds, matching IPC/JEDEC Class 3 profiles.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy at 125 °C?
From 25 °C to 125 °C (ΔT = 100 K), the Zener voltage shifts by −0.35 V, resulting in a regulated value of ~2.71 V (3.06 V − 0.35 V). This is within the device's specified min/max range (2.94–3.06 V at 25 °C) and remains usable for non-critical biasing where ±100 mV deviation is acceptable.
