Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 (Vishay) | TVS diode, 130 V standoff, 150 W peak power, bidirectional; higher capacitance (150 pF), no Zener regulation mode. | Used for faster transient suppression but lacks precision voltage reference capability in DC bias circuits. | Select when surge speed (<1 ns) matters more than DC regulation stability; not suitable as shunt reference. |
| P6SMB130A (ON Semiconductor) | TVS diode, same 130 V standoff, 600 W peak power, DO-214AA package; larger footprint, higher leakage (>10 μA @ 104 V). | Targeted at board-level ESD/surge protection rather than embedded voltage reference or high-temp sensor biasing. | Choose for higher surge energy handling where space permits; avoid in compact, high-reliability automotive modules. |
Compared with BZD27B130P-HE3_A18, SMBJ130A-E3/52 offers faster response but no DC regulation function, while P6SMB130A provides higher surge capacity in a less space-efficient package - making BZD27B130P-HE3_A18 optimal for AEC-Q101-compliant, high-precision, high-temperature Zener applications requiring both clamping and reference stability.

Yes, BZD27B130P-HE3_A18 is explicitly AEC-Q101 qualified, as indicated by the "-HE3" suffix per Vishay's ordering nomenclature. It meets stress tests including temperature cycling, humidity bias HAST, and mechanical shock - validated for use in engine control units, battery management systems, and other automotive subsystems requiring long-term reliability under vibration and thermal extremes.
What is the clamping voltage of BZD27B130P-HE3_A18 at 5 A surge current?
The clamping voltage of BZD27B130P-HE3_A18 is 110 V at 5 A peak surge current (IRSM), as specified in the "Electrical Characteristics" table on page 3 of the Vishay datasheet (Document No. 85921). This value defines the maximum voltage seen by downstream components during standardized 10/1000 μs surge events and is critical for selecting compatible MOSFETs and ICs with appropriate voltage margins.
Which package does BZD27B130P-HE3_A18 use, and is it RoHS-compliant?
BZD27B130P-HE3_A18 uses the SMF (DO-219AB) package - a low-profile surface-mount outline measuring 2.7 mm × 3.5 mm × 1.08 mm, compatible with SOD-123W footprints. It is RoHS-compliant per the "-HE3" designation and meets UL 94 V-0 flammability rating and J-STD-020 MSL level 1, allowing standard reflow processing without moisture sensitivity concerns.
What is the maximum junction temperature rating for BZD27B130P-HE3_A18?
The maximum junction temperature (Tj) for BZD27B130P-HE3_A18 is 175 °C, as stated in the Absolute Maximum Ratings table on page 2 of the Vishay datasheet. This rating enables reliable operation in under-hood automotive locations and high-temperature industrial enclosures, supported by thermal resistance values of RthJL = 30 K/W and RthJA = 180 K/W (on 3 mm × 3 mm Cu pads).
