Product details
Overview
TDZ7V5J,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 7.5 V at 5 mA, with differential resistance ≤80 Ω, total power dissipation up to 500 mW, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ7V5J,115 datasheet, TDZ7V5J,115 pinout, TDZ7V5J,115 application, or TDZ7V5J,115 equivalent, key selection criteria include its 7.5 V ±0.15 V working voltage tolerance, 5.0 mV/K temperature coefficient, 170 A non-repetitive peak reverse current capability, and suitability for space-constrained SMT designs requiring stable clamping under transient conditions.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals. Its low differential resistance (≤80 Ω at IZ = 5 mA) ensures minimal voltage variation under load changes, while the 5.0 mV/K temperature coefficient enables predictable drift behavior over −55 °C to +150 °C ambient range.
The device supports surge handling up to 40 W non-repetitive peak reverse power (tp = 100 μs), with thermal resistance from junction to solder point at 25 K/W-critical for PCB-level thermal management in automotive and industrial control modules where localized heating must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.5 V to 7.65 V at IZ = 5 mA - defines precise clamping threshold for overvoltage protection |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA - ensures tight regulation under varying load currents |
| Temperature Coefficient SZ | +2.5 mV/K at IZ = 5 mA - enables predictable voltage drift compensation in wide-temperature environments |
| Total Power Dissipation Ptot | 500 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Reverse Current IZSM | 4.0 A at tp = 100 μs - supports ESD and surge immunity in I/O protection circuits |
| Reverse Current IR | ≤1 μA at VR = 5 V - guarantees low leakage in standby or battery-powered systems |
| Junction Temperature Range | −55 °C to +150 °C - validated for under-hood automotive and industrial control applications |
Pinout & Package
SOD323F (SC-90) is a 2-pin ultra-small flat-lead surface-mount plastic package measuring 2.7 mm × 1.6 mm × 0.95 mm, optimized for high-density PCB layouts and automated assembly. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B7V5,115 | Same 7.5 V nominal Zener voltage but higher differential resistance (100 Ω vs. 80 Ω); no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and tighter regulation is not required |
| MMSZ5236B-TP | 7.5 V Zener with 100 Ω rdif, 350 mW Ptot, and SOD-123 package (larger footprint than SOD323F) | Requires more PCB area; lower surge rating (25 W vs. 40 W) limits use in high-transient environments | Choose only if legacy SOD-123 footprint compatibility is mandatory and thermal headroom permits reduced power rating |
Compared with BZX384-B7V5,115 and MMSZ5236B-TP, TDZ7V5J,115 provides superior regulation stability, automotive qualification, and space efficiency-making it optimal for next-generation compact, mission-critical embedded systems where reliability and board area are constrained.

FAQ
What is the maximum continuous Zener current for TDZ7V5J,115 at 25 °C ambient?
The device supports a maximum forward current of 250 mA per datasheet limiting values, but continuous Zener operation is governed by thermal limits. At Tamb = 25 °C, the 500 mW total power dissipation limit corresponds to approximately 66.7 mA at 7.5 V-this is the practical upper bound for sustained regulation without derating.
Does TDZ7V5J,115 require heatsinking on standard FR4 PCB?
No additional heatsinking is required for typical operation. With Rth(j-a) = 250 K/W and Rth(j-sp) = 25 K/W, the device achieves adequate thermal performance using the recommended 16 mm² cathode pad on single-sided tin-plated FR4-sufficient for ≤500 mW dissipation at ambient temperatures up to 70 °C.
How does the +2.5 mV/K temperature coefficient affect circuit design?
This positive coefficient means VZ increases by 2.5 mV per Kelvin rise in junction temperature. For a 50 °C rise above 25 °C, VZ shifts +125 mV-designers must account for this in precision references by either compensating with negative-TC components or restricting operating temperature range to ±10 °C for sub-25 mV error budgets.
Can TDZ7V5J,115 replace older TDZ7V5 models in existing designs?
Yes-TDZ7V5J,115 maintains identical electrical specifications, pinout, and package dimensions as prior revisions of the TDZ7V5 series. The "J" suffix denotes AEC-Q101 qualification, and "115" indicates 3,000-unit tape-and-reel packaging; no layout or schematic changes are needed for drop-in replacement.
