Product details
Overview
TDZ13J,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 13 V at 5 mA, with differential resistance ≤170 Ω, total power dissipation up to 500 mW at 25 °C ambient, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ13J,115 datasheet, TDZ13J,115 pinout, TDZ13J,115 application, or TDZ13J,115 equivalent, this device is selected for low-profile voltage reference, ESD clamp stabilization, and reverse-bias surge suppression where thermal resistance to solder point (25 K/W) and non-repetitive peak reverse current capability (2.5 A) are critical design factors.
Technical Context
The TDZ13J,115 operates as a two-terminal, silicon planar Zener diode optimized for stable reverse breakdown under controlled current. Its Zener voltage is specified at 12.7–13.3 V (min/max) at IZ = 5 mA, with temperature coefficient of +7.0 to +11 mV/K - indicating positive drift above ~5.6 V, enabling predictable thermal compensation in bias networks.
It exhibits low dynamic impedance (170 Ω max at 5 mA), reverse leakage <0.1 µA at 10 V, and junction-to-solder-point thermal resistance of 25 K/W on FR4 PCB with 16 mm² cathode pad - enabling reliable transient energy handling (40 W non-repetitive peak power) without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.7–13.3 V at IZ = 5 mA - defines precise clamping threshold for 12 V rail protection |
| Differential Resistance (rdif) | ≤170 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - sets continuous DC power limit before thermal derating |
| Non-repetitive Peak Reverse Current (IZSM) | 2.5 A at tp = 100 µs - supports transient surge absorption per IEC 61000-4-5 |
| Thermal Resistance (Rth(j-sp)) | 25 K/W - enables rapid heat transfer to PCB copper, critical for pulse reliability |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 10 V - guarantees low standby current in high-impedance bias networks |
| Temperature Coefficient (SZ) | +7.0 to +11 mV/K - allows predictable voltage drift compensation in temperature-sensitive references |
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.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B13,115 | Same SOD323F package; tighter VZ tolerance (±2%) but higher rdif (200 Ω max) and no AEC-Q101 qualification | Preferred for consumer-grade precision references where automotive qualification is unnecessary | Select when ±2% voltage accuracy outweighs surge robustness and automotive reliability requirements |
| MMSZ5242BT1G | SOD-123 package (larger footprint); VZ = 13.0 V ±5%, rdif = 30 Ω max, but only rated to 500 mW with Rth(j-a) = 350 K/W | Suitable for non-space-constrained industrial boards where thermal margin is less critical than cost | Choose when board area is not constrained and lower dynamic impedance is prioritized over package size |
Compared with BZX384-B13,115 and MMSZ5242BT1G, TDZ13J,115 uniquely balances AEC-Q101 compliance, ultra-compact SOD323F packaging, and 25 K/W junction-to-solder-point thermal resistance - making it optimal for automotive and portable electronics where reliability, size, and pulse thermal performance are jointly critical.

FAQ
What is the maximum continuous forward current rating for TDZ13J,115?
The TDZ13J,115 is not rated for continuous forward conduction; its absolute maximum forward current is 250 mA under pulsed conditions (tp ≤ 300 µs). In normal Zener operation, it functions in reverse bias only - forward voltage is 1.1 V at 100 mA, but sustained forward current degrades reliability and is outside intended use.
Can TDZ13J,115 be used as a replacement for a 12 V Zener diode?
No - TDZ13J,115 has a nominal Zener voltage of 13 V (12.7–13.3 V range), not 12 V. Using it in place of a true 12 V Zener would raise clamping voltage by ~1 V, potentially exceeding downstream IC absolute maximum ratings. For 12 V regulation, TDZ12J (11.8–12.2 V) is the correct variant in the same series.
Does TDZ13J,115 require a heatsink for 500 mW operation?
No external heatsink is required. At 500 mW dissipation, the device relies on PCB copper as its thermal path: with a 16 mm² tin-plated cathode pad on FR4, its junction-to-solder-point thermal resistance is 25 K/W, limiting temperature rise to ~12.5 °C above solder point - well within the 150 °C max junction rating.
How does the temperature coefficient affect TDZ13J,115 in precision reference circuits?
With a temperature coefficient of +7.0 to +11 mV/K, TDZ13J,115's Zener voltage increases ~100 mV over a 10 °C ambient rise. In precision references, this drift must be compensated - either via complementary NTC networks or by selecting operating current where SZ is minimized (per Fig 3–4 in datasheet), typically near IZ = 1–5 mA.
