Product details
Overview
TDZ16J,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 16.0 V at 5 mA, with differential resistance ≤200 Ω, total power dissipation up to 500 mW, and AEC-Q101 qualification for automotive-grade reliability - used in ECU reference rails and sensor biasing networks.
For engineers reviewing the TDZ16J,115 datasheet, TDZ16J,115 pinout, TDZ16J,115 application, or TDZ16J,115 equivalent, key selection criteria include Zener voltage tolerance (±3.1%), temperature coefficient (+10.4 mV/K), non-repetitive peak reverse current (1.5 A), thermal resistance junction-to-solder point (25 K/W), and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, clamping reverse-biased voltage at its specified breakdown level with low dynamic impedance. Its silicon planar construction ensures stable Zener characteristics across −55 °C to +150 °C ambient range and supports fast transient response due to low junction capacitance (97 pF at VR = 0 V).
The device uses a cathode-anode terminal configuration with polarity marked by a bar on the SOD323F body. It is rated for non-repetitive surge events up to 100 µs square wave pulses and meets IEC 60134 absolute maximum ratings, including 150 °C junction temperature limit and 500 mW steady-state power dissipation at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7–16.3 V at IZ = 5 mA - defines precise clamping threshold for overvoltage protection and reference stability |
| Differential Resistance (rdif) | ≤200 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation, critical for tight-tolerance regulation |
| Reverse Current (IR) | ≤0.05 µA at VR = 11.2 V - guarantees ultra-low leakage in standby or battery-powered sensing nodes |
| Temperature Coefficient (SZ) | +10.4 mV/K at IZ = 5 mA - quantifies positive drift per degree, enabling accurate thermal compensation in automotive environments |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB with 16 mm² cathode pad |
| Non-repetitive Peak Reverse Current (IZSM) | 1.5 A at tp = 100 µs - supports ESD/ISO 7637-2 pulse immunity without degradation |
| Junction-to-Solder Point Thermal Resistance (Rth(j-sp)) | 25 K/W - enables effective heat transfer to PCB copper, sustaining reliability under intermittent surges |
Pinout & Package
SOD323F (SC-90) is a surface-mount plastic package measuring 2.7 × 1.6 × 0.95 mm, optimized for automated placement and reflow soldering. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity mark aligns with PCB silkscreen 'K' or band; requires ≥16 mm² tin-plated copper pad for thermal performance |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased path during Zener conduction; no marking on package |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS sensors, with extended temperature cycling and HTRB testing |
| Low differential resistance | 200 Ω typical at 5 mA - maintains <±20 mV regulation error across ±10 mA load current changes |
| Very small SMD package | SOD323F footprint (2.7 × 1.6 mm) - saves >60% board area vs. DO-35, enabling miniaturized power management in space-constrained modules |
| Controlled temperature coefficient | +10.4 mV/K - predictable positive drift allows deterministic compensation in closed-loop reference designs |
| High surge robustness | 1.5 A non-repetitive peak reverse current - withstands ISO 16750-2 pulse 5a (load dump) when paired with series impedance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B16,115 | Same SOD323F package, but ±5% VZ tolerance (15.2–16.8 V) vs. TDZ16J's ±3.1%; higher rdif (300 Ω) | Acceptable where tighter regulation not required; lower cost for consumer-grade power supplies | Select when budget constraints outweigh need for low dynamic impedance and automotive qualification |
| MMSZ4687T1G | Higher VZ tolerance (±5%), 350 mW Ptot, no AEC-Q101 rating; TO-236AB (SOT-23) package | Used in commercial IoT gateways; lacks thermal performance (Rth(j-a) = 350 K/W vs. 250 K/W) | Choose only for non-automotive, non-safety-critical designs where board space allows larger SOT-23 footprint |
Compared with BZX384-B16,115 and MMSZ4687T1G, TDZ16J,115 offers superior regulation precision (±3.1% VZ), lower impedance (200 Ω), and automotive qualification - making it the sole choice for ECU reference rails requiring long-term stability under thermal stress.

FAQ
What is the maximum continuous reverse power this diode can handle?
The TDZ16J,115 has a total power dissipation limit of 500 mW at ambient temperature ≤25 °C when mounted on an FR4 PCB with a 16 mm² tin-plated cathode pad. Derating is required above 25 °C at 4.2 mW/°C, reaching zero dissipation at 150 °C ambient. This rating assumes natural convection cooling and excludes surge conditions.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a specified +10.4 mV/K temperature coefficient at 5 mA, the Zener voltage increases by approximately 1.3 V across −40 °C to +125 °C. For example, nominal 16.0 V shifts to ~14.7 V at −40 °C and ~16.0 V + 1.3 V = 17.3 V at +125 °C. System-level compensation must account for this linear drift in precision reference applications.
Can TDZ16J,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel operation is not recommended. For higher power, use a single higher-rated Zener or add external series pass transistor with feedback control.
Is the SOD323F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with peak temperature up to 260 °C for ≤10 seconds. The SOD323F outline matches IPC-7351B standard land pattern (2.2 × 0.95 mm solder lands), and thermal mass is optimized for Type 3 solder paste and standard 4-zone reflow profiles.
