Product details
Overview
PDZ13B,135 from Nexperia is a single low-power Zener diode in SOD323 (SC-76) package, designed for precision voltage regulation at 13.2 V nominal working voltage with ±2 % tolerance, 80 Ω max differential resistance at IZ = 5 mA, and 0.1 µA max reverse leakage at VR = 10 V - deployed in power supply reference rails and overvoltage protection circuits.
For engineers reviewing the PDZ13B,135 datasheet, PDZ13B,135 pinout, PDZ13B,135 application, or PDZ13B,135 equivalent, this device serves as a compact, surface-mount voltage reference with hard breakdown knee, low thermal drift (+9.4 mV/K), and validated performance on FR4 PCBs under standard footprint reflow conditions.
Technical Context
The PDZ13B,135 operates as a two-terminal voltage reference diode, conducting in reverse bias above its specified Zener voltage (12.91–13.49 V at IZ = 5 mA) with sharp knee characteristics and minimal dynamic impedance. Its junction temperature range extends to +150 °C, and it maintains stable regulation under pulsed reverse currents up to 2.5 A (tp = 100 µs).
Thermal resistance from junction to solder point is 130 K/W, enabling reliable operation at up to 400 mW total power dissipation on standard FR4 PCBs. Forward voltage is ≤0.9 V at 10 mA, supporting bidirectional verification during board-level testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.91–13.49 V at IZ = 5 mA - defines precise regulation threshold for 13.2 V nominal reference |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Leakage IR | ≤0.1 µA at VR = 10 V - guarantees low quiescent current in standby regulation paths |
| Temperature Coefficient SZ | +9.4 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive references |
| Total Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling under standard mounting |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - supports functional continuity check without forward-bias damage |
| Package | SOD323 (SC-76) - 1.35 mm × 0.8 mm footprint optimized for high-density SMT layouts |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|

| Low dynamic impedance | 80 Ω max at 5 mA enables tight voltage control under varying load conditions |
| Low leakage current | 0.1 µA max at 10 V reduces error contribution in high-impedance reference dividers |
| Stable temperature coefficient | +9.4 mV/K allows predictable drift modeling for compensated designs |
| SMD-optimized thermal performance | 130 K/W junction-to-solder-point resistance supports reliable derating on FR4 |
Applications
| Power Supply Reference Rail | Overvoltage Clamp Protection |
|---|---|
|
Use Scenario: Stabilizing feedback node in adjustable DC-DC converter ICs (e.g., LM317, TL431-based supplies). IC Role / Device Role / Timing Role: Provides fixed 13.2 V reference for error amplifier comparison, setting output voltage accuracy. Use Value: ±2 % VZ tolerance and 80 Ω rdif limit output drift to <±15 mV across 1–10 mA load steps. |
Use Scenario: Clamping transient surges on 12 V automotive accessory lines or industrial sensor inputs. IC Role / Device Role / Timing Role: Shunts excess energy above 13.2 V to ground before downstream circuitry reaches breakdown. Use Value: Hard knee and 2.5 A non-repetitive peak surge rating enable robust clamping without thermal runaway. |
| ADC Voltage Reference Buffer | Microcontroller Reset Threshold |
|
Use Scenario: Biasing precision voltage reference ICs (e.g., REF5013) requiring low-noise, low-drift input. IC Role / Device Role / Timing Role: Supplies clean, thermally stable 13.2 V pre-regulation to reduce noise coupling into reference buffers. Use Value: +9.4 mV/K SZ and 0.1 µA IR minimize reference drift and loading error in 24-bit SAR ADC systems. |
Use Scenario: Setting brown-out detection threshold for 12 V–15 V microcontroller supply monitoring. IC Role / Device Role / Timing Role: Triggers reset logic when main rail drops below 12.9 V (VZ min), ensuring deterministic restart. Use Value: Tight 12.91–13.49 V VZ window provides 500 mV hysteresis margin against ripple-induced false resets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal VZ, but ±5 % tolerance (vs. ±2 %), higher rdif (100 Ω), and no published SZ spec | Acceptable where cost sensitivity outweighs precision; unsuitable for temp-compensated references | Select when budget constraints dominate and ±5 % regulation is acceptable |
| MMSZ5243B | 13 V nominal VZ, ±5 % tolerance, 100 Ω rdif, 0.1 µA IR, but SOD123 package (larger footprint) | Compatible for space-tolerant boards; thermal resistance ~250 K/W limits power handling | Choose only if SOD323 footprint is unavailable and board area permits larger package |
Compared with BZX84-C13 and MMSZ5243B, PDZ13B,135 delivers tighter voltage tolerance, lower dynamic impedance, and documented temperature coefficient - making it preferred for precision reference and thermally constrained SMT designs.

FAQ
What is the maximum continuous reverse current the PDZ13B,135 can sustain at 25 °C ambient?
The PDZ13B,135 does not specify a maximum continuous reverse current independent of power dissipation. At 25 °C ambient on an FR4 PCB, its 400 mW power limit restricts continuous Zener current to approximately 30 mA (400 mW ÷ 13.2 V), assuming full regulation at nominal VZ. Derating applies above 25 °C per Fig. 1.
Does the PDZ13B,135 support wave soldering, and what is the recommended footprint?
Yes - Nexperia specifies wave soldering compatibility for PDZ13B,135 using the SOD323 footprint in Figure 10: 2.9 mm × 1.2 mm solder lands, 5 mm transport direction length, and defined solder resist clearance. Thermal profile must stay within JEDEC J-STD-020 limits for plastic packages.
How is the cathode identified on the PDZ13B,135 package?
The cathode is marked by a visible bar on the top surface of the SOD323 package, aligned with Pin 1 per Table 2 and Figure 8. This marking matches the "K" designation in the pinning diagram and corresponds to the terminal labeled "1" in the simplified outline graphic.
Can PDZ13B,135 be used in place of PDZ12B or PDZ15B without circuit modification?
No - although all belong to the same PDZ-B series, their Zener voltages differ significantly: PDZ12B (11.74–12.24 V), PDZ13B,135 (12.91–13.49 V), and PDZ15B (14.34–14.98 V). Substitution alters regulation setpoint by >1 V, requiring recalibration of feedback dividers or clamp thresholds.
