Product details
Overview
TDZ10J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and reference functions in space-constrained PCB layouts. It delivers a nominal Zener voltage of 10 V (9.80–10.20 V at IZ = 5 mA), 150 Ω typical differential resistance, ≤0.20 µA reverse current at VR = 8 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TDZ10J,115 datasheet, TDZ10J,115 pinout, TDZ10J,115 application, or TDZ10J,115 equivalent, this device serves as a compact, thermally efficient voltage clamp in power supply feedback loops, overvoltage protection circuits, and low-power reference stages where stable 10 V regulation under 500 mW total dissipation is required.
Technical Context
The TDZ10J,115 operates as a two-terminal voltage-reference device with cathode-anode polarity defined by a marking bar. Its Zener breakdown mechanism provides stable reverse-bias regulation with a temperature coefficient of +4.5 to +8.0 mV/K across 25 °C–150 °C, enabling predictable drift compensation in analog sensing and feedback paths.
Thermal performance is characterized by Rth(j-a) = 250 K/W (free air) and Rth(j-sp) = 25 K/W (to solder point), supporting reliable operation on FR4 PCBs with 16 mm² cathode pad area. Non-repetitive peak reverse power dissipation is rated at 40 W for pulse durations ≤100 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.80–10.20 V at IZ = 5 mA - defines precise clamping threshold for 10 V reference applications |
| Differential Resistance rdif | 150 Ω max - ensures low output impedance and minimal regulation error under load variation |
| Reverse Current IR | ≤0.20 µA at VR = 8 V - guarantees high off-state blocking for low-leakage protection circuits |
| Total Power Dissipation Ptot | 500 mW at Tamb ≤ 25 °C - sets thermal design boundary for continuous operation on standard FR4 |
| Non-repetitive Peak Power PZSM | 40 W - supports transient surge suppression in automotive load-dump or ESD scenarios |
| Temperature Coefficient SZ | +4.5 to +8.0 mV/K - enables predictable voltage drift modeling for temperature-compensated designs |

Pinout & Package
SOD323F (SC-90) is a 2-pin surface-mount plastic package measuring 2.7 × 1.6 × 0.95 mm (L × W × H), optimized for high-density PCB assembly and reflow soldering. The cathode is marked by a visible bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-B10,115 | Same 10 V nominal Zener voltage, but higher differential resistance (200 Ω max) and no AEC-Q101 qualification | Approved for commercial-grade consumer power supplies only; not validated for automotive thermal cycling or humidity testing | Select when cost sensitivity outweighs automotive qualification and tighter regulation is not required |
| MMSZ4686T1G | 10 V Zener with 100 Ω max rdif, but only 300 mW Ptot and no specified surge rating | Suitable for low-power logic-level clamping, but insufficient for sustained 500 mW dissipation or 40 W transient absorption | Prefer for space-constrained digital I/O protection where thermal margin is ample and surge immunity is secondary |
Compared with BZX384-B10,115 and MMSZ4686T1G, the TDZ10J,115 uniquely combines AEC-Q101 qualification, 500 mW continuous dissipation, and 40 W surge capability in a sub-3 mm footprint-making it the only option qualified for automotive-grade 10 V reference and clamping in thermally demanding environments.

FAQ
What is the maximum continuous forward current for TDZ10J,115?
The TDZ10J,115 is a Zener diode intended for reverse-bias operation; its forward current rating is 250 mA maximum per absolute maximum ratings. Forward conduction is not its functional mode, and sustained forward bias above 1.1 V at 100 mA may cause thermal overstress outside specification limits.
Can TDZ10J,115 be used in parallel for higher power handling?
No-Zener diodes exhibit manufacturing spread in VZ and temperature coefficient; paralleling TDZ10J,115 units causes current imbalance and thermal runaway. For higher power, use a single higher-rated Zener or implement active regulation instead.
Is the SOD323F package compatible with standard reflow profiles?
Yes-the TDZ10J,115 SOD323F package is qualified for lead-free reflow soldering per J-STD-020. Recommended profile includes peak temperature ≤260 °C, time above 217 °C ≤60 seconds, and ramp rate ≤3 °C/s to ensure mechanical and electrical integrity.
How does the +4.5 to +8.0 mV/K temperature coefficient affect circuit accuracy?
This positive coefficient means VZ increases ~6.5 mV per °C rise. At 100 °C ambient (ΔT = 75 °C), VZ shifts +0.49 V-requiring compensation in precision references. For non-critical clamping, the shift remains within system tolerance bands.
