Product details

Overview

TDZ2V7J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and reference functions at 2.7 V nominal Zener voltage (2.65–2.75 V), with 450 Ω typical differential resistance at I_Z = 5 mA, 500 mW total power dissipation at T_amb ≤ 25 °C, and AEC-Q101 qualification for automotive-grade reliability in compact PCB space-constrained designs.

For engineers reviewing the TDZ2V7J,115 datasheet, TDZ2V7J,115 pinout, TDZ2V7J,115 application, or TDZ2V7J,115 equivalent, key selection considerations include its low-voltage Zener tolerance (±1.85%), thermal coefficient (−3.5 mV/K), non-repetitive surge capability (15 A peak reverse current), and suitability for biasing, overvoltage clamping, and reference stabilization in automotive sensor interfaces and low-power microcontroller reset circuits.

Technical Context

This device operates as a two-terminal voltage-reference diode with sharp reverse-breakdown characteristics at 2.7 V, optimized for stable DC regulation under low-current conditions (I_Z = 1–5 mA). Its −3.5 mV/K temperature coefficient ensures predictable drift across −55 °C to +150 °C ambient range, and its 450 Ω differential resistance supports tight regulation in feedback paths.

The SOD323F package enables high-density surface-mount placement with minimal thermal resistance (R_th(j-sp) = 25 K/W to solder point), while AEC-Q101 qualification confirms robustness against mechanical stress, temperature cycling, and humidity exposure required for automotive body electronics and infotainment power rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	2.65–2.75 V at I_Z = 5 mA - defines precise clamping threshold for 2.7 V rail protection
Differential Resistance (r_dif)	450 Ω max at I_Z = 5 mA - determines regulation stiffness and output impedance in reference circuits
Total Power Dissipation (P_tot)	500 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB
Non-repetitive Peak Reverse Current (I_ZSM)	15 A at t_p = 100 μs - supports transient overvoltage suppression without failure
Temperature Coefficient (S_Z)	−3.5 mV/K - quantifies voltage drift per degree Celsius, critical for temperature-stable references
Reverse Current (I_R)	20 μA max at V_R = 1 V - indicates leakage level affecting standby power in battery-powered systems
Forward Voltage (V_F)	1.1 V max at I_F = 100 mA - defines conduction loss when used in forward-biased protection configurations

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-B2V7,115	Same 2.7 V nominal Zener voltage but ±5% tolerance (2.57–2.84 V); higher 600 Ω r_dif; SOD323 package	Less precise regulation; suitable for non-critical biasing where tighter tolerance is not required	Select for cost-sensitive consumer applications where ±5% V_Z is acceptable and AEC-Q101 is unnecessary
MMSZ4678T1G	2.7 V nominal but ±5% tolerance; 500 mW P_tot; SOD-123 package (larger footprint, higher R_th(j-a) = 300 K/W)	Lower thermal performance limits continuous power in confined layouts; no AEC-Q101 qualification	Choose when board layout allows larger SOD-123 and automotive qualification is not mandated

Compared with BZX384-B2V7,115 and MMSZ4678T1G, TDZ2V7J,115 delivers superior voltage accuracy (±1.85% vs. ±5%), lower thermal resistance (25 K/W vs. ≥300 K/W), and automotive-grade reliability-making it optimal for safety-critical or thermally constrained designs where regulation stability and long-term consistency are essential.

FAQ

What is the maximum continuous reverse power this diode can handle?

TDZ2V7J,115 has a total power dissipation limit of 500 mW at ambient temperature ≤25 °C when mounted on an FR4 PCB with specified 16 mm² cathode pad. Derating is required above 25 °C per the 250 K/W junction-to-ambient thermal resistance; at 85 °C ambient, maximum usable power drops to approximately 300 mW.

Is this Zener diode suitable for automotive applications?

Yes-TDZ2V7J,115 is AEC-Q101 qualified, having passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias. It is rated for operation from −55 °C to +150 °C junction temperature and is widely used in automotive body control modules, sensor interfaces, and infotainment power supplies.

How does the marking code "3B" relate to the part number?

The marking "3B" on the device body corresponds exclusively to TDZ2V7J per Nexperia's official marking table; "3" denotes the TDZxJ series family, and "B" identifies the 2.7 V Zener voltage variant. This marking is laser-etched on the cathode side of the SOD323F package and is verified under 20× magnification per JEDEC standards.

Can this diode be used in forward conduction mode?

Yes-TDZ2V7J,115 exhibits a forward voltage of ≤1.1 V at 100 mA, making it usable as a low-drop rectifier or clamping diode in forward bias. However, its primary design intent and characterization are for reverse-bias Zener operation; forward parameters are secondary and not optimized for high-current switching applications.
