Product details
Overview
DFLZ5V6Q-7 from Diodes Incorporated is a 1.0W surface-mount power Zener diode in PowerDI123 package, with nominal Zener voltage 5.6V (±5% tolerance), 100mA test current, 1Ω typical Zener impedance, and -0.04%/°C to +0.04%/°C temperature coefficient. It delivers stable voltage regulation in automotive power supply rails and industrial overvoltage protection circuits.
For engineers reviewing the DFLZ5V6Q-7 datasheet, DFLZ5V6Q-7 pinout, DFLZ5V6Q-7 application, or DFLZ5V6Q-7 equivalent, key selection criteria include Zener voltage accuracy at 100mA, thermal resistance junction-to-solder point (9°C/W), AEC-Q101 qualification, RoHS-compliant matte tin finish, and PowerDI123 package thermal performance on FR-4 PCB.
Technical Context
This Zener diode operates in reverse breakdown mode to clamp transient voltages and regulate reference points. Its patented interlocking clip design enables high-surge capacity per US Patent #7,095,113, and the exposed cathode pad provides low thermal resistance (RθJS = 9°C/W) for reliable 1W dissipation on standard FR-4 layouts.
It is qualified to AEC-Q101 for automotive use, features halogen- and antimony-free "Green" molding compound (UL 94V-0), and maintains stable regulation across -55°C to +150°C operating range with minimal voltage drift due to its tightly controlled ±0.04%/°C tempco at nominal Zener current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6V nominal, 5.2–6.0V min/max at IZT = 100mA - ensures precise clamping in 5V rail protection |
| Power Dissipation (PD) | 1.0W on FR-4 PCB - supports sustained regulation without heatsink in space-constrained designs |
| Zener Impedance (ZZT) | 1Ω typical at IZT = 100mA - minimizes output voltage variation under dynamic load changes |
| Thermal Resistance (RθJS) | 9°C/W junction-to-solder point - enables efficient heat transfer to PCB copper pour |
| Tempco (αVZ) | -0.04 to +0.04%/°C - guarantees stable reference voltage across automotive temperature range |
| Reverse Leakage (IR) | 10µA max at VR = 2.5V - ensures low standby power loss in always-on circuits |
| Forward Voltage (VF) | 1.2V at IF = 200mA - allows use as polarity-sensitive clamp or ESD path in bidirectional protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | 0.3W rating, SOT-23 package, RθJA = 300°C/W, no AEC-Q101 qualification | Limited to low-power consumer electronics; unsuitable for automotive or industrial 1W surge environments | Select only for cost-sensitive, non-automotive, low-duty-cycle applications |
| MMSZ5232BS | 0.5W rating, SOD-123 package, ZZT = 10Ω typical, tempco ±0.05%/°C | Higher impedance causes greater regulation error under load; lacks interlocking clip for surge robustness | Acceptable for static reference use but not for transient suppression in harsh environments |
Compared with BZX84-C5V6 and MMSZ5232BS, DFLZ5V6Q-7 offers superior thermal performance (9°C/W vs. >200°C/W), AEC-Q101 reliability, and patented surge resilience - making it the only choice for automotive-grade 1W Zener regulation where long-term stability and transient immunity are critical.

FAQ
What is the maximum continuous power dissipation for DFLZ5V6Q-7 on a standard PCB?
DFLZ5V6Q-7 is rated for 1.0W continuous power dissipation when mounted on a 1.5" × 1.5" FR-4 board with 2 oz. copper and a 1" × 1" cathode pad layout. Derating begins above +25°C ambient, reaching zero power at +150°C per the published derating curve.
Does DFLZ5V6Q-7 have a defined forward voltage specification?
Yes - forward voltage is specified as 1.2V maximum at 200mA forward current. This value supports use in dual-role configurations, such as combined reverse-clamp and forward-polarity ESD protection, and confirms compatibility with standard silicon diode drive expectations.
How is the cathode identified on the PowerDI123 package?
The cathode is marked by a distinct band on the top surface of the PowerDI123 package, aligned with the cathode terminal. The exposed metal pad on the bottom side is electrically and thermally connected to the cathode, and must be soldered to a PCB copper area for proper thermal and electrical performance.
Is DFLZ5V6Q-7 suitable for use in life support equipment?
No - Diodes Incorporated explicitly prohibits use of DFLZ5V6Q-7 in life support devices or systems without express written approval from its CEO. It is not authorized for implantable, sustaining-life, or safety-critical medical applications where failure could cause injury.
