Product details
Overview
PZU9.1DB2,115 from Nexperia is a dual isolated Zener diode pair in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact surface-mounted circuits. It delivers 9.1 V nominal Zener voltage (±2 % tolerance), 60 Ω typical differential resistance at 5 mA, and supports non-repetitive peak reverse power dissipation up to 40 W with 100 µs square-wave pulses - used in automotive ECU power rail clamping and industrial sensor signal conditioning.
For engineers reviewing the PZU9.1DB2,115 datasheet, PZU9.1DB2,115 pinout, PZU9.1DB2,115 application, or PZU9.1DB2,115 equivalent, this part serves as a space-constrained, AEC-Q101-qualified dual Zener solution requiring stable 9.1 V reference, low capacitance (120 pF @ 1 MHz), and thermal robustness up to 150 °C junction temperature.
Technical Context
The PZU9.1DB2,115 integrates two electrically isolated Zener diodes in a single 5-pin SOT353 package, enabling independent regulation or bidirectional clamping without shared cathode/anode paths. Each diode exhibits a temperature coefficient of +5.5 mV/K at 5 mA, ensuring predictable drift behavior across automotive temperature ranges.
Its 250 mW total power dissipation (at Tamb ≤25 °C) and 455 K/W junction-to-ambient thermal resistance (on FR4 PCB with standard footprint) support reliable operation in thermally constrained PCB layouts. The device is qualified to AEC-Q101, confirming suitability for automotive-grade transient suppression and reference stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.85 V to 9.23 V at IZ = 5 mA - tight ±2 % tolerance enables accurate 9.1 V reference without external trimming. |
| Differential Resistance (rdif) | 60 Ω max at IZ = 5 mA - low impedance ensures stable regulation under varying load current. |
| Reverse Current (IR) | 0.5 µA max at VR = 7.5 V - minimal leakage preserves battery-powered circuit standby efficiency. |
| Diode Capacitance (Cd) | 120 pF at f = 1 MHz, VR = 0 V - low capacitance avoids signal integrity degradation in high-frequency analog interfaces. |
| Non-repetitive Peak Reverse Current (IZSM) | 3.5 A at tp = 100 µs - supports robust ESD/ISO 7637-2 pulse clamping in automotive electronics. |
| Junction Temperature (Tj) | −55 °C to +150 °C - rated for under-hood automotive environments and industrial control enclosures. |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing, including HTRB, HTGB, and temperature cycling. |
Pinout & Package
SOT353 (SC-88A) is a 5-lead, very small outline surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density PCB assembly and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first Zener diode; connects to regulated node when cathode (Pin 5) is grounded. |
| 2 | Not Connected | Internally unconnected; must remain floating - no PCB trace or thermal pad connection permitted. |
| 3 | Anode (Diode 2) | Independent input for second Zener diode; enables dual-rail or complementary clamping configurations. |
| 4 | Cathode (Diode 2) | Output/reference terminal for Diode 2; ties to system ground or bias rail for regulation. |
| 5 | Cathode (Diode 1) | Output/reference terminal for Diode 1; electrically isolated from Pin 4, allowing separate grounding paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener configuration | Two independent diodes share no internal connection - eliminates crosstalk and enables asymmetric clamping topologies. |
| ±2 % Zener voltage tolerance (B2 series) | Reduces need for post-assembly calibration in precision reference designs, lowering test time and cost. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity, and high-temperature reverse bias life testing. |
| Halogen-free option available (PZU9.1DB2/DG) | Meets RoHS and ELV compliance requirements without compromising thermal or electrical performance. |
| Low 120 pF capacitance at 1 MHz | Preserves signal fidelity in sensor front-ends and communication line protectors operating up to 10 MHz. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Clamping CAN transceiver supply rails against load-dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Dual Zener provides bidirectional overvoltage protection on 12 V and 5 V rails using independent cathodes (Pins 4 and 5) tied to separate ground planes. Use Value: 40 W non-repetitive peak power rating absorbs 100 µs surges without degradation; AEC-Q101 qualification ensures field reliability. |
Use Scenario: Protecting 4–20 mA current loop receiver inputs from induced surges in factory floor wiring. IC Role / Device Role / Timing Role: One diode regulates reference voltage for ADC biasing; the other clamps input amplifier rail during EFT bursts. Use Value: 60 Ω differential resistance maintains <1 % regulation error across 1–10 mA load variation; 150 °C Tj rating sustains operation near hot motor drives. |
| Consumer Wearable Battery Monitor | Medical Diagnostic Sensor Interface |
Use Scenario: Providing stable 9.1 V reference for lithium-ion cell voltage measurement in smart watches. IC Role / Device Role / Timing Role: Zener diode (Diode 1) supplies precision reference to ADC; Diode 2 unused or configured as backup. Use Value: ±2 % tolerance eliminates need for digital calibration; 0.5 µA leakage at 7.5 V extends battery life beyond 3 years in standby. |
Use Scenario: Guarding low-noise instrumentation amplifier inputs against electrostatic discharge in portable ultrasound probes. IC Role / Device Role / Timing Role: Dual diodes placed in series-anti-parallel configuration across differential input pins for symmetric ESD clamping. Use Value: 120 pF capacitance avoids resonance with 10 kΩ input impedance above 130 kHz; isolation prevents common-mode coupling into sensitive analog path. |
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-C9V1 | Single Zener in SOT23; no dual-isolation capability; 5 % tolerance; 150 mW Ptot. | Requires two devices for dual-rail use; higher voltage drift due to wider tolerance and no AEC-Q101 validation. | Select only for cost-sensitive, non-automotive consumer applications where board space and qualification are secondary. |
| PZU9.1D,115 | Same SOT353 package but single Zener die; lacks second isolated diode; identical 9.1 V spec and AEC-Q101 rating. | Cannot implement independent dual-rail regulation or asymmetric clamping; reduces design flexibility in multi-voltage systems. | Choose when only one regulated rail is needed and BOM simplification outweighs dual-diode functionality. |
Compared with BZX84-C9V1 and PZU9.1D,115, the PZU9.1DB2,115 uniquely delivers two AEC-Q101-qualified Zeners in one footprint with ±2 % tolerance and isolated terminals - enabling compact, robust dual-rail protection without sacrificing thermal or electrical performance.

FAQ
What is the maximum continuous power dissipation for PZU9.1DB2,115 at 70 °C ambient?
At 70 °C ambient temperature, the derated total power dissipation is 175 mW, calculated using the 250 mW rating at 25 °C and thermal resistance of 500 K/W (free air). This ensures safe operation without exceeding 150 °C junction temperature under steady-state conditions.
Can Pin 2 be used as a heatsink or ground connection?
No - Pin 2 is internally not connected and must remain unconnected on the PCB. Routing traces or thermal pads to Pin 2 violates the device's internal construction and may cause mechanical stress or solder joint reliability issues during thermal cycling.
How does the +5.5 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over that range, the Zener voltage shifts by approximately ±0.47 V (5.5 mV/K × 85 K), resulting in a worst-case VZ of 8.38 V to 9.70 V. For high-accuracy applications, this drift must be compensated in system-level calibration or mitigated via temperature-sensing feedback.
Is the PZU9.1DB2,115 compatible with lead-free reflow profiles per JEDEC J-STD-020?
Yes - the SOT353 package and halogen-free molding compound are qualified for standard lead-free reflow with peak temperatures up to 260 °C (per JEDEC J-STD-020D), including 60-second exposure above 217 °C and ramp rates compliant with Class 3 assembly requirements.
