Product details
Overview
TDZ2V4J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation at 2.4 V nominal Zener voltage with ±0.05 V tolerance, 400 Ω differential resistance at 5 mA, and 500 mW total power dissipation at 25 °C ambient. It serves as a low-voltage reference or clamp in automotive sensor signal conditioning circuits.
For engineers reviewing the TDZ2V4J,115 datasheet, TDZ2V4J,115 pinout, TDZ2V4J,115 application, or TDZ2V4J,115 equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C junction temperature rating, 2.35–2.45 V working voltage range at 5 mA, and suitability for space-constrained PCB layouts requiring stable low-voltage regulation.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage under varying load and temperature conditions. Its negative temperature coefficient of −3.5 mV/K ensures predictable drift behavior across −55 °C to +150 °C ambient range.
Designed for surface-mount use on FR4 PCBs with 16 mm² cathode pad, it delivers 180 W non-repetitive peak reverse power dissipation (tp ≤ 100 μs) and exhibits 450 pF diode capacitance at 0 V reverse bias, supporting moderate-frequency noise suppression in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.35–2.45 V at IZ = 5 mA - defines precise clamping threshold for 2.4 V rail protection |
| Differential Resistance (rdif) | 400 Ω max at IZ = 5 mA - determines regulation stiffness and output impedance in feedback paths |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 board |
| Reverse Current (IR) | 50 μA max at VR = 1.0 V - ensures low leakage in standby mode for battery-powered systems |
| Thermal Resistance (Rth(j-a)) | 250 K/W in free air - governs junction-to-ambient temperature rise under steady-state operation |
| Non-repetitive Peak Power (PZSM) | 180 W for tp ≤ 100 μs - enables transient overvoltage suppression without device failure |
| Temperature Coefficient (SZ) | −3.5 mV/K - quantifies voltage drift per degree Celsius, critical for high-accuracy references |
Pinout & Package
SOD323F (SC-90) plastic surface-mounted package: 2-pin, ultra-compact footprint (2.7 × 1.6 mm), flat lead profile optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar on package identifies this terminal |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V4,115 | Same 2.4 V nominal Zener voltage but higher differential resistance (600 Ω max) and lower surge rating (100 W) | Limited to non-automotive consumer electronics due to lack of AEC-Q101 qualification | Select when cost sensitivity outweighs automotive reliability requirements and surge immunity |
| MMSZ4676T1G | 2.4 V Zener with 500 mW Ptot but wider VZ tolerance (±5%) and no specified AEC-Q101 status | Suitable for general-purpose regulation where ±5% output variation is acceptable | Choose for industrial control boards where extended temperature validation is not mandated |
Compared with BZX384-B2V4,115 and MMSZ4676T1G, TDZ2V4J,115 offers superior regulation precision (±0.05 V), guaranteed automotive qualification, and highest transient power handling-making it the preferred choice for safety-critical or thermally demanding designs.

FAQ
What is the maximum continuous forward current for TDZ2V4J,115?
The maximum continuous forward current is 250 mA, verified per Absolute Maximum Ratings in the Nexperia datasheet Rev. 2 (2011). This rating applies at Tamb ≤ 25 °C with proper PCB thermal relief; derating is required above ambient temperatures.
Does TDZ2V4J,115 support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's official guidance. Hand-soldering is not advised due to thermal stress risks on the SOD323F package; the device lacks specifications for iron tip temperature or dwell time, and manual process may compromise AEC-Q101 reliability.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy at 105 °C?
At 105 °C ambient (ΔT = +80 K from 25 °C reference), the Zener voltage shifts by −280 mV, resulting in VZ ≈ 2.17 V. This is confirmed by Figure 3 in the datasheet and must be accounted for in high-temperature reference designs.
Is the 180 W non-repetitive peak power rating valid for all pulse widths?
No-the 180 W rating applies only for pulses ≤100 μs (square wave, Tj = 25 °C pre-surge). For longer pulses, derating is required per Figure 1: e.g., at 300 μs, maximum PZSM drops to ~120 W, and at 1 ms, it falls below 60 W.
