Product details
Overview
DDZX8V2C-13 from Diodes Incorporated is a surface-mount precision Zener diode in SOT23 package, rated for 300 mW power dissipation on FR-4 PCB, with nominal Zener voltage 8.2 V (min 8.03 V, max 8.45 V at IZT = 20 mA), Zener impedance of 8 Ω at IZT, and reverse leakage current ≤0.5 μA at VR = 6.5 V. It is AEC-Q101 qualified and used for voltage regulation and reference in automotive and industrial power supply rails.
For engineers reviewing the DDZX8V2C-13 datasheet, DDZX8V2C-13 pinout, DDZX8V2C-13 application, or DDZX8V2C-13 equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, automotive-grade reliability validation, and direct alternatives with documented voltage tolerance and impedance differences.
Technical Context
This Zener diode operates in reverse breakdown mode with sharp knee characteristics, enabling stable voltage reference under low-current conditions (IZK = 0.5 mA). Its 8.2 V nominal rating places it in the medium-voltage range where temperature coefficient crosses zero - confirmed by Fig. 16 showing TC ≈ 0 %/°C near 8 V.
The device uses alloy 42 leadframe with matte tin annealed finish, meets J-STD-020 Level 1 moisture sensitivity, and is packaged in 10,000-piece tape-and-reel format (-13 suffix). Thermal resistance RθJA is 417 °C/W when mounted on FR-4 with recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.03–8.45 V at IZT = 20 mA - ensures tight regulation tolerance (±2.6%) for precision reference applications |
| Zener Impedance (ZZT) | 8 Ω at IZT = 20 mA - low dynamic resistance maintains stable output under load transients |
| Power Dissipation (PD) | 300 mW on FR-4 PCB - defines maximum continuous DC power handling without forced cooling |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 6.5 V - minimizes quiescent current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 417 °C/W - determines junction-to-ambient temperature rise per watt; requires layout-aware thermal design |
| Operating Temperature | −65 to +150 °C - supports extended-range operation in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for high-reliability automotive use including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SOT23 - three-terminal surface-mount plastic package with standard JEDEC outline; case material is halogen- and antimony-free "Green" molding compound (UL 94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal / cathode reference ground path | Connected to system ground or lower-potential node in shunt regulator configuration |
| Cathode (Pin 2) | Zener breakdown terminal / regulated output node | Provides stable 8.2 V reference when reverse-biased through current-limiting resistor |
| No Connection (Pin 3) | Internal die attach flag / mechanical support | Not electrically connected; serves as heatsink tab and mechanical anchor in SOT23 body |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp breakdown knee | Enables accurate voltage clamping at low test currents (IZK = 0.5 mA), reducing minimum operating current requirements |
| Tight VZ tolerance (±2.6%) | Reduces need for post-assembly trimming in reference circuits; improves batch consistency in production |
| Low leakage (≤0.5 μA @ 6.5 V) | Minimizes error contribution in high-resistance divider networks and battery-powered sensor references |
| AEC-Q101 qualification | Validates robustness for automotive engine control units, body electronics, and ADAS power domains |
| SOT23 compatibility with automated assembly | Supports high-speed pick-and-place and reflow soldering without tombstoning or alignment issues |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2 | Zener voltage 8.2 V (±5%), ZZT = 15 Ω at 5 mA, PD = 350 mW, no AEC-Q101 qualification | Higher impedance and wider tolerance reduce regulation accuracy; suitable only for non-automotive consumer designs | Select when cost is primary concern and automotive qualification is unnecessary |
| MMSZ5236B | Zener voltage 8.2 V (±5%), ZZT = 10 Ω at 20 mA, PD = 500 mW, RoHS-compliant but not AEC-Q101 qualified | Higher power rating allows greater current margin but lacks automotive reliability validation and tighter VZ spread | Prefer for industrial power supplies needing higher surge tolerance but no automotive certification |
Compared with BZX84-C8V2 and MMSZ5236B, DDZX8V2C-13 offers superior voltage tolerance (±2.6% vs. ±5%), lower ZZT (8 Ω vs. ≥10 Ω), and AEC-Q101 qualification - making it the only choice for safety-critical automotive voltage references where long-term stability and process reliability are mandatory.

FAQ
What is the maximum continuous Zener current for DDZX8V2C-13 at 25°C?
The device is rated for 300 mW power dissipation. At its nominal 8.2 V Zener voltage, the maximum continuous Zener current is approximately 36.6 mA (300 mW ÷ 8.2 V). However, the datasheet specifies test condition IZT = 20 mA, and derating must be applied above 25°C per Figure 1's power derating curve.
Does DDZX8V2C-13 have a specified temperature coefficient?
Yes - Figure 16 shows the typical temperature coefficient of VZ versus Zener voltage for DDZX6V2B–DDZX10C. At 8.2 V, the TC is approximately 0 %/°C, indicating minimal voltage drift over temperature, which is critical for precision reference applications.
Can DDZX8V2C-13 replace DDZX8V2B in an existing design?
No - DDZX8V2B has tighter tolerance (±2.0% vs. ±2.6% for DDZX8V2C) and lower ZZT (7 Ω vs. 8 Ω), per Electrical Characteristics Table. While functionally similar, the C-grade variant trades some precision for broader availability and cost efficiency; redesign validation is required for interchangeability.
Is the SOT23 package of DDZX8V2C-13 compatible with standard reflow profiles?
Yes - the device is qualified for lead-free reflow per JEDEC J-STD-020, with Moisture Sensitivity Level 1. No floor life limitation applies, and standard Pb-free reflow profiles (peak 260°C, 60 sec max) are supported without preconditioning.
