Product details
Overview
TDZ22J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and overvoltage protection in space-constrained PCBs. It delivers a nominal Zener voltage of 22 V at 5 mA, with differential resistance ≤250 Ω, total power dissipation up to 500 mW at 25 °C ambient, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ22J,115 datasheet, TDZ22J,115 pinout, TDZ22J,115 application, or TDZ22J,115 equivalent, key selection factors include its 21.6–22.4 V working voltage range, low thermal resistance (25 K/W junction-to-solder-point), 150 °C max junction temperature, and suitability for transient suppression in 12 V/24 V automotive subsystems.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its temperature coefficient of +15.4 to +16.4 mV/K at 5 mA enables predictable drift compensation in bias networks.
The device supports non-repetitive peak reverse power dissipation up to 40 W (tp = 100 µs), with thermal resistance from junction to ambient of 250 K/W in free air - critical for short-duration surge clamping in ESD-protected interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 21.6 V to 22.4 V at IZ = 5 mA - defines precise clamping threshold for 24 V rail protection |
| Differential Resistance (rdif) | ≤250 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - sets continuous DC power limit for thermal design on FR4 PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs - supports transient surge handling per ISO 7637-2 Pulse 1/2a |
| Reverse Current (IR) | ≤0.05 µA at VR = 17.6 V - guarantees low leakage in high-impedance reference circuits |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD testing |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.7 mm × 1.6 mm footprint, 0.65 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

| Low thermal resistance | Rth(j-sp) = 25 K/W to solder point - improves power handling without heatsinking on standard FR4 |
| Precision Zener voltage tolerance | ±2.3 % at 22 V nominal - reduces need for post-production trimming in voltage reference designs |
| Automotive-grade reliability | AEC-Q101 qualified with 150 °C Tj rating - meets ASIL-B supporting component requirements |
| Controlled temperature coefficient | +15.4 to +16.4 mV/K - allows predictable bias point shift across −40 °C to +125 °C operating range |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B22,115 | Same SOD323F package; VZ = 21.7–22.3 V at 5 mA; rdif = 220 Ω; Ptot = 300 mW | Lower power rating limits continuous dissipation in high-current clamp scenarios | Select when thermal budget is constrained and peak surges are infrequent |
| MMSZ5247B-TP | SOD-123 package; VZ = 21.2–22.8 V at 20 mA; rdif = 35 Ω; Ptot = 500 mW; no AEC-Q101 qualification | Larger footprint (3.7 × 1.6 mm) and unqualified status restrict automotive use | Prefer for cost-sensitive industrial designs where AEC compliance is not required |
Compared with BZX384-B22,115 and MMSZ5247B-TP, TDZ22J,115 uniquely combines AEC-Q101 qualification, 250 K/W junction-to-ambient thermal resistance, and 22 V regulation in the smallest SOD323F footprint - making it optimal for space- and reliability-critical automotive voltage references.

FAQ
What is the maximum continuous reverse current the TDZ22J,115 can sustain at 25 °C ambient?
The TDZ22J,115 sustains up to 22.7 mA continuous reverse current at 25 °C ambient, calculated from its 500 mW total power dissipation rating and nominal 22 V Zener voltage (Ptot/VZ = 0.5 W / 22 V). This assumes no additional thermal derating and proper PCB copper area for heat dissipation.
How does the cathode marking appear on the TDZ22J,115 package?
The cathode is identified by a visible bar marking on the top surface of the SOD323F package, aligned with pin 1. The physical outline shows two terminals: pin 1 (cathode, marked) and pin 2 (anode, unmarked), consistent with the simplified graphic symbol in Nexperia's data sheet Rev. 2 (2011).
Is the TDZ22J,115 suitable for bidirectional ESD protection?
No - the TDZ22J,115 is a unidirectional Zener diode optimized for reverse-bias regulation and clamping. It lacks symmetrical breakdown characteristics required for bidirectional ESD protection; dedicated TVS diodes like PESD5V0S1BA should be used instead for IEC 61000-4-2 compliance.
What is the recommended soldering profile for TDZ22J,115?
Nexperia specifies reflow soldering only, with peak temperature ≤260 °C for ≤10 seconds, preheat ramp rate ≤3 °C/s, and time above 217 °C limited to 60–150 seconds. The SOD323F package requires strict adherence to these parameters to avoid delamination or internal bond damage.
