Product details
Overview
PZU2.7DB2,115 from Nexperia is a dual isolated Zener diode pair in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact DC power rails. It delivers 2.7 V nominal Zener voltage per diode with ±2 % tolerance, 40 W non-repetitive peak reverse power dissipation, and 250 mW total power dissipation at 25 °C ambient - used in automotive sensor supply conditioning and industrial I/O interface clamping.
For engineers reviewing the PZU2.7DB2,115 datasheet, PZU2.7DB2,115 pinout, PZU2.7DB2,115 application, or PZU2.7DB2,115 equivalent, this page provides verified pin functions, AEC-Q101 qualification status, dual-diode isolation behavior, thermal resistance (Rth(j-a) = 500 K/W), and halogen-free packaging compliance - all critical for automotive-grade board-level surge protection design.
Technical Context
The PZU2.7DB2,115 integrates two electrically isolated Zener diodes in a single 5-pin SOT353 package, enabling independent regulation or bidirectional clamping without internal coupling. Each diode supports 200 mA forward current and exhibits 1000 Ω typical differential resistance at IZ = 5 mA.
Its −2.0 mV/K temperature coefficient at 2.7 V ensures stable reference performance across −55 °C to +150 °C junction range, while 440 pF capacitance at 1 MHz and 0 V reverse bias suits low-speed signal line protection - not RF or high-speed data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.65 V to 2.9 V at IZ = 5 mA - defines tight regulation window for 2.7 V rail stabilization |
| Tolerance | ±2 % (B2 series) - enables accurate voltage threshold setting without external trimming |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - handles ESD transients per IEC 61000-4-2 Level 4 (8 kV contact) |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - limits continuous thermal load on PCB land patterns |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - ensures low conduction loss during forward-biased clamp operation |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports under-hood automotive environments and industrial control cabinets |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and ESD |
Pinout & Package
SOT353 (SC-88A) 5-lead surface-mount plastic package with 0.65 mm lead pitch; halogen-free, dark-green molding compound; standard footprint compatible with reflow and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first Zener diode; reverse-biased to regulate/clamp relative to cathode 5 |
| 2 | Not Connected | Internal die pad with no electrical connection - must remain unconnected on PCB |
| 3 | Anode (Diode 2) | Input terminal for second Zener diode; reverse-biased to regulate/clamp relative to cathode 4 |
| 4 | Cathode (Diode 2) | Reference node for Diode 2; ties to system ground or regulated rail return path |
| 5 | Cathode (Diode 1) | Reference node for Diode 1; electrically isolated from pin 4 - enables dual-rail or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener configuration | Enables independent voltage regulation on two separate nets without shared cathode paths |
| ±2 % Zener voltage tolerance (B2 series) | Reduces need for post-production calibration in precision 2.7 V reference circuits |
| AEC-Q101 qualification | Validates reliability for automotive body electronics, infotainment power supplies, and ADAS sensor interfaces |
| Halogen-free / dark-green package (DG variant) | Meets RoHS and ELV Directive requirements; eliminates brominated flame retardants in PCB assembly |
| 40 W non-repetitive peak power rating | Supports transient suppression per ISO 7637-2 Pulse 1/2a/3a without external TVS cascading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C2V7 | Single Zener in SOT23; no dual-isolation capability; 5 % tolerance; 300 mW Ptot | Requires two devices for dual-rail use; higher voltage drift; lacks AEC-Q101 validation | Select only for cost-sensitive non-automotive designs where dual isolation is unnecessary |
| MMBZ5221BS | Single Zener in SOT323; ±5 % tolerance; 200 mW Ptot; no AEC-Q101 rating | Smaller footprint but no dual-diode integration; unsuitable for automotive under-hood deployment | Use when board space is constrained and dual functionality is implemented externally |
Compared with BZX84-C2V7 and MMBZ5221BS, the PZU2.7DB2,115 uniquely delivers certified automotive reliability, matched dual-Zener matching, and integrated isolation - eliminating layout complexity and component count in safety-critical 2.7 V reference and clamping systems.

FAQ
Is PZU2.7DB2,115 pin-compatible with other SOT353 dual Zener diodes?
Yes - it uses standard SOT353 (SC-88A) pinout with anode-cathode-anode-cathode-NC arrangement. Pin 2 is internally unconnected and must remain floating on PCB; no alternate pin mappings exist within the PZUxDB2 family or industry-standard dual Zeners in this package.
What is the maximum continuous reverse current for stable 2.7 V regulation?
At 25 °C, the device maintains regulation up to 5 mA reverse current (IZ = 5 mA), where VZ = 2.65 V to 2.9 V and differential resistance is 1000 Ω. Continuous operation above 5 mA increases self-heating and requires derating per thermal resistance (Rth(j-a) = 500 K/W).
Does the /DG suffix affect electrical performance?
No - the /DG suffix indicates halogen-free, dark-green molding compound only. All electrical parameters, thermal characteristics, and pinout are identical between PZU2.7DB2 and PZU2.7DB2/DG; the /DG variant complies with EU RoHS and ELV directives without performance trade-offs.
Can PZU2.7DB2,115 be used for bidirectional ESD protection on a single signal line?
Yes - by connecting pin 1 and pin 4 together as the signal line, and tying pins 3 and 5 to ground, the device forms a symmetrical Zener clamp. This configuration leverages both diodes to limit ±2.7 V excursions, delivering 40 W peak clamping in either polarity per IEC 61000-4-2 testing.
