Product details
Overview
BZT5250H-C13-Q from Nexperia is a low-current Zener diode in SOD123F package, providing 12.35 V to 13.65 V nominal regulation at 50 µA test current, with ±5 % tolerance, 170 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive voltage reference and biasing functions.
For engineers reviewing the BZT5250H-C13-Q datasheet, BZT5250H-C13-Q pinout, BZT5250H-C13-Q application, or BZT5250H-C13-Q equivalent, this part supports low-power voltage stabilization in battery-powered sensor nodes, automotive ECU reference rails, and precision analog front-ends where leakage-limited biasing and thermal stability are critical.
Technical Context
This Zener diode operates as a two-terminal shunt voltage regulator, optimized for low-test-current (50 µA) operation to minimize quiescent power draw in always-on circuits. Its intentional minor leakage rise improves switching speed and reduces noise in feedback paths.
Designed per IEC 60134 absolute maximum ratings, it sustains 830 mW total power dissipation at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad, and features a junction-to-ambient thermal resistance of 150 K/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35 V to 13.65 V at IZ = 50 µA - defines stable regulation range for low-bias reference design |
| Tolerance | ±5 % - enables cost-effective selection within E24 voltage series without tight-bin sorting |
| Differential Resistance (rdiff) | 170 Ω max at IZ = 5 mA - determines output impedance and load regulation error in shunt configuration |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - ensures minimal forward drop when used in polarity-sensitive protection or clamping |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB layout |
| Junction Temperature (Tj) | 150 °C max - defines upper thermal limit for reliable operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - confirms stress-test compliance for discrete semiconductors in automotive applications |
Pinout & Package
SOD123F surface-mount plastic package: 2.6 mm × 1.6 mm × 1.1 mm body, flat lead, single-sided copper FR4 mounting, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated voltage node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-biased Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables use in microamp-level bias networks without compromising regulation accuracy |
| Optimized leakage profile | Intentional minor IR rise per AN90031 - reduces switching transients and high-frequency noise in feedback loops |
| Automotive qualification | AEC-Q101 compliant - validated for temperature cycling, HTRB, and ESD robustness required in vehicle ECUs |
| Thermal performance | Rth(j-sp) = 150 K/W - supports stable regulation under ambient temperatures up to +150 °C with proper pad layout |
| Small-form-factor packaging | SOD123F footprint - allows high-density placement in space-constrained modules like ADAS sensors and body controllers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C13 | Same Zener voltage range (12.35–13.65 V) but ±5 % tolerance only; no AEC-Q101 qualification; Ptot = 500 mW | Not suitable for automotive production; limited to industrial or consumer-grade designs with relaxed reliability requirements | Select when cost sensitivity outweighs automotive qualification and higher power margin is unnecessary |
| MMSZ5242B | 13 V nominal, ±5 %, SOD-123 package, Ptot = 500 mW, rdiff = 30 Ω typical at 20 mA - lower impedance but higher test current (20 mA) | Higher bias current demand limits use in sub-µA sleep circuits; better for higher-current analog references | Prefer when tighter dynamic regulation is needed and system can support 20 mA Zener current |
Compared with BZT5250H-C13-Q, BZT52-C13 lacks automotive qualification and thermal derating headroom, while MMSZ5242B trades low-bias capability for lower dynamic impedance - making the BZT5250H-C13-Q optimal for AEC-Q101-compliant, ultra-low-quiescent designs.

FAQ
What is the minimum reverse current required to achieve specified Zener voltage for BZT5250H-C13-Q?
The device is specified at IZ = 50 µA, with VZ guaranteed between 12.35 V and 13.65 V under those conditions. Operation below 50 µA results in reduced regulation accuracy and increased rdiff; datasheet does not guarantee VZ outside this test condition.
Can BZT5250H-C13-Q be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, select a single higher-rated Zener or use active regulation instead.
How does the "intentional minor rise of leakage current" affect circuit performance?
This design feature, detailed in Application Note AN90031, slightly increases reverse leakage near breakdown to reduce minority-carrier storage time, thereby improving transient response and lowering high-frequency noise in feedback paths - beneficial in precision analog and fast-switching applications.
Is the SOD123F package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with footprint dimensions provided in Figure 10. The package supports JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and withstands peak reflow temperatures up to 260 °C for 30 seconds.
