Product details
Overview
TDZ4V7J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and reference functions at 4.7 V nominal Zener voltage (4.61–4.79 V at IZ = 5 mA), with 500 mW total power dissipation, 80 Ω typical differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ4V7J,115 datasheet, TDZ4V7J,115 pinout, TDZ4V7J,115 application, or TDZ4V7J,115 equivalent, key selection criteria include Zener voltage tolerance (±2.0%), low thermal resistance (Rth(j-sp) = 25 K/W), reverse current ≤3 µA at VR = 3.25 V, temperature coefficient of +0.2 mV/K, and suitability for compact PCB space-constrained designs.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage under varying load or input conditions. Its Zener voltage is specified at 5 mA test current with ±2.0% tolerance and exhibits a positive temperature coefficient (+0.2 mV/K) near 4.7 V, minimizing drift across ambient temperatures from −55 °C to +150 °C.
Thermal performance is defined by junction-to-solder-point resistance of 25 K/W on FR4 PCB with 16 mm² cathode pad, enabling reliable operation up to 150 °C junction temperature. Non-repetitive peak reverse power dissipation reaches 180 W for pulses ≤100 µs, supporting transient suppression in automotive supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.61–4.79 V at IZ = 5 mA - defines precise regulation point for 4.7 V reference circuits |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - ensures low output impedance and minimal voltage shift under load variation |
| Reverse Current (IR) | ≤3 µA at VR = 3.25 V - guarantees low leakage in standby or low-power monitoring modes |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤25 °C - sets continuous DC power limit for thermal design on standard FR4 PCB |
| Temperature Coefficient (SZ) | +0.2 mV/K at IZ = 5 mA - provides predictable, low-drift behavior over industrial temperature range |
| Junction Temperature (Tj) | −55 to +150 °C - supports operation in under-hood automotive and industrial control environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC standard |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.3–2.7 mm length, 1.15–1.35 mm width, 0.25–0.40 mm height; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | SOD323F package occupies <1.5 mm² PCB area - enables high-density layout in space-constrained modules |
| Low differential resistance | 80 Ω max - improves regulation accuracy under dynamic load changes in feedback loops |
| AEC-Q101 qualification | Validated for automotive applications - eliminates need for additional reliability screening in Tier-1 BOMs |
| Stable temperature coefficient | +0.2 mV/K - reduces calibration burden in temperature-sensitive sensor signal conditioning |

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 |
|---|---|---|---|
| BZX84-C4V7,115 | Same SOD323 package, but ±5% VZ tolerance (4.47–4.94 V) vs. ±2.0% for TDZ4V7J,115; rdif = 90 Ω max | Lower cost for non-critical regulation; unsuitable where <±2.5% reference stability required | Select when budget constraints outweigh precision needs and thermal drift sensitivity is low |
| MMSZ4704T1G | SOD-123 package (larger footprint); VZ = 4.7 V ±5%, rdif = 100 Ω, Ptot = 350 mW | Higher thermal resistance limits power handling in dense layouts; not AEC-Q101 qualified | Choose only if SOD-123 is already standardized in legacy designs and automotive qualification is unnecessary |
Compared with BZX84-C4V7,115 and MMSZ4704T1G, TDZ4V7J,115 delivers tighter voltage tolerance, lower dynamic impedance, higher surge robustness, and automotive-grade reliability-making it the preferred choice for next-generation automotive and industrial systems demanding long-term parametric stability.

FAQ
What is the maximum continuous forward current rating for TDZ4V7J,115?
The absolute maximum forward current (IF) is 250 mA per the limiting values table. However, sustained forward conduction is not its intended operating mode; the device is optimized for reverse-bias Zener regulation. Forward voltage is specified at 100 mA (VF ≤1.1 V), but thermal limits and application context typically restrict forward use to brief transient conditions.
Can TDZ4V7J,115 be used in place of a 5.1 V Zener diode?
No-TDZ4V7J,115 has a nominal Zener voltage of 4.7 V (4.61–4.79 V), not 5.1 V. Substituting it for a 5.1 V part would cause systematic under-regulation by ~0.4 V, potentially violating downstream IC supply or reference requirements. The TDZ5V1J variant in the same series provides 5.00–5.20 V regulation and shares identical package and reliability specs.
How does the AEC-Q101 qualification impact board-level design?
AEC-Q101 qualification confirms the device has passed accelerated stress tests-including high-temperature operating life, temperature cycling, and ESD-specifically for automotive environments. This eliminates the need for additional qualification testing at the system level and assures long-term reliability in vibration-prone, thermally aggressive locations such as engine compartments or dashboard assemblies.
What is the recommended PCB pad layout for optimal thermal performance?
The datasheet specifies a 16 mm² tin-plated copper pad for the cathode on FR4 PCB. The reflow footprint diagram shows 0.6 mm wide solder lands with 0.95 mm spacing. Using this layout achieves the stated Rth(j-sp) = 25 K/W; reducing pad area increases thermal resistance and risks exceeding 150 °C junction temperature under 500 mW dissipation.
