Product details
Overview
BZD27C30P-HE3-08 from Vishay Semiconductors is a unidirectional, AEC-Q101-qualified Zener diode in DO-219AB (SMF) package, designed for precision voltage regulation and transient overvoltage protection. It delivers a nominal Zener voltage of 30 V at 25 mA test current, with ±2 V tolerance (28–32 V), 42.2 V clamping voltage at 24 A surge, and temperature coefficient of +0.06 to +0.11 %/°C.
For engineers reviewing the BZD27C30P-HE3-08 datasheet, BZD27C30P-HE3-08 pinout, BZD27C30P-HE3-08 application, or BZD27C30P-HE3-08 equivalent, this device supports automotive-grade power rail stabilization, ESD-sensitive interface protection, and high-reliability industrial voltage reference circuits where low leakage (<5 µA at 24 V), surge robustness (150 W, 10/1000 µs), and MSL Level 1 handling are critical.
Technical Context
This Zener diode operates as a single-element, unidirectional voltage clamp with defined breakdown characteristics under both DC regulation and transient surge conditions. Its junction temperature rating of 175 °C and thermal resistance of 30 K/W (junction-to-lead) enable stable operation in high-ambient automotive engine control units and industrial power supplies.
The device exhibits a typical dynamic impedance of 22 Ω at 25 mA and a reverse leakage current ≤5 µA at VR = 24 V, supporting low-power biasing and precise threshold detection. Its AEC-Q101 qualification confirms suitability for automotive applications requiring reliability under thermal cycling, mechanical shock, and humidity exposure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | TVS diode (not Zener); 30 V standoff, 48.4 V clamping at 12.3 A; higher capacitance (150 pF) | Designed for fast transient suppression (ns response), not DC regulation; lacks precision VZ specification | Select when primary need is ESD/EMI surge clamping rather than stable voltage reference |
| BZX84-C30 | SOT-23 package; 28–32 V VZ at 5 mA; lower surge rating (100 W), no AEC-Q101 qualification | Lower power handling and non-automotive qualification limit use to consumer/commercial PCBs | Select for cost-sensitive, non-automotive designs where space constraints favor SOT-23 over DO-219AB |
Compared with SMBJ30A and BZX84-C30, the BZD27C30P-HE3-08 uniquely combines AEC-Q101 qualification, 150 W surge capability, and tight 28–32 V Zener tolerance in a low-profile DO-219AB package-making it the preferred choice for automotive and industrial systems requiring both regulation accuracy and transient resilience.

FAQ
What is the Zener voltage tolerance of BZD27C30P-HE3-08?
The BZD27C30P-HE3-08 has a Zener voltage range of 28 V to 32 V at 25 mA test current, corresponding to a nominal 30 V with ±2 V absolute tolerance. This specification is verified per Vishay's datasheet revision 2.1 and applies under standard test conditions (TA = 25 °C). The BZD27C30P-HE3-08 maintains this tolerance across its qualified operating temperature range.
Is BZD27C30P-HE3-08 suitable for automotive applications?
Yes, the BZD27C30P-HE3-08 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics. It meets JESD201 Class 2 whisker testing, HBM ESD >8 kV, and operates from -65 °C to +175 °C. The BZD27C30P-HE3-08 also supports wave and reflow soldering per J-STD-020 MSL Level 1.
What is the maximum clamping voltage of BZD27C30P-HE3-08 during surge events?
The BZD27C30P-HE3-08 clamps to 42.2 V at a peak surge current of 24 A under the 10/1000 µs waveform condition. This value is specified in the Vishay datasheet and reflects worst-case transient suppression performance. The BZD27C30P-HE3-08 achieves this while maintaining low dynamic impedance (22 Ω) and minimal leakage (<5 µA).
Which package does BZD27C30P-HE3-08 use, and what are its key mechanical features?
The BZD27C30P-HE3-08 uses the DO-219AB (SMF) package: a low-profile surface-mount outline measuring 2.7 mm × 3.5 mm × 0.85 mm, with cathode band marking and 8 mm tape compatibility. Its MSL Level 1 rating allows unlimited floor life, and peak reflow temperature is rated to 260 °C. The BZD27C30P-HE3-08's footprint matches industry-standard SMF land patterns.
How does the temperature coefficient affect BZD27C30P-HE3-08 performance in real-world circuits?
The BZD27C30P-HE3-08 has a positive temperature coefficient of +0.06 to +0.11 %/°C, meaning its Zener voltage increases slightly with rising junction temperature. At 100 °C above ambient, VZ rises by ~6–11 mV/°C × 100 °C = 0.6–1.1 V. This behavior is stable and predictable, allowing designers to compensate in feedback loops-especially critical in the BZD27C30P-HE3-08's target applications like automotive power supplies.
