Product details
Overview
P6SMB16AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM = 13.6 V), 22.5 V clamping voltage at 26.7 A peak pulse current (10/1000 μs), and 600 W peak pulse power. It provides robust ESD and surge protection for DC power rails and signal lines in automotive and industrial control modules.
For engineers reviewing the P6SMB16AHE3/52 datasheet, P6SMB16AHE3/52 pinout, P6SMB16AHE3/52 application, or P6SMB16AHE3/52 equivalent, this AEC-Q101 qualified TVS diode delivers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability PCB assembly and automotive-grade transient suppression design.
Technical Context
The P6SMB16AHE3/52 operates as a unidirectional avalanche breakdown device with glass-passivated junction, enabling fast response (<1 ns) to transients and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ = 150 °C) support operation in compact, convection-cooled layouts.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. The cathode band identifies polarity, and its SMB footprint aligns with IPC-7351B standard pad dimensions (0.205" × 0.130").
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/52 | Same VWM (13.6 V), but lower PPPM = 400 W and higher VC = 26.5 V at 17.4 A. | Limited to lower-energy transients (e.g., IEC 61000-4-4 EFT); unsuitable for full IEC 61000-4-5 Level 4. | Select when cost sensitivity outweighs surge margin, and system-level testing confirms 400 W sufficiency. |
| 1.5SMC16A | Same VWM/VC, but larger SMC (DO-214AB) package (2.54 mm height) and higher RθJA = 125 °C/W. | Requires more board area and exhibits greater thermal rise under repeated surges; not AEC-Q101 qualified. | Choose only if legacy SMC footprint compatibility is mandatory and automotive qualification is not required. |
Compared with SMAJ16A-E3/52 and 1.5SMC16A, P6SMB16AHE3/52 delivers superior surge robustness (600 W vs. 400 W/600 W), automotive qualification, and lower profile - making it optimal for space-constrained, high-reliability 12 V systems where clamping voltage margin and reflow compatibility are critical.

FAQ
What is the clamping voltage of P6SMB16AHE3/52 at its rated peak pulse current?
The P6SMB16AHE3/52 has a maximum clamping voltage (VC) of 22.5 V at IPPM = 26.7 A using a 10/1000 μs waveform. This value is measured under standardized conditions per JEDEC and ensures predictable voltage limiting during surge events. The clamping performance is guaranteed across the full operating temperature range (−65 °C to +150 °C) and is validated in Vishay's AEC-Q101 qualification testing for P6SMB16AHE3/52.
Is P6SMB16AHE3/52 suitable for automotive applications?
Yes, P6SMB16AHE3/52 is AEC-Q101 qualified, with full test reports covering HTOL, temperature cycling, mechanical shock, and ESD (HBM ≥ 8 kV). Its HE3 suffix explicitly denotes automotive-grade qualification, and it is used in engine control units, body control modules, and ADAS sensor interfaces where sustained reliability under thermal and electrical stress is required. P6SMB16AHE3/52 meets all stress requirements defined in the AEC-Q101 standard.
What does the "HE3" suffix mean in P6SMB16AHE3/52?
The "HE3" suffix in P6SMB16AHE3/52 indicates RoHS-compliant construction and AEC-Q101 qualification. "H" denotes automotive qualification, "E3" specifies lead (Pb)-free, RoHS-compliant matte tin plating. This distinguishes it from commercial-grade E3 or M3 variants and confirms compliance with automotive supply chain traceability and material content requirements. P6SMB16AHE3/52 is fully documented in Vishay's automotive product change notifications.
How does P6SMB16AHE3/52 differ from bidirectional versions like P6SMB16CA?
P6SMB16AHE3/52 is unidirectional, with polarity marked by a cathode band and specified parameters (VWM, VBR, VC) applying only in reverse bias. In contrast, P6SMB16CA is bidirectional - symmetrical in both directions, no polarity marking, and intended for AC line or differential signal protection. P6SMB16AHE3/52 must be oriented correctly in-circuit; reversing it would forward-bias the anode and cause failure. Its unidirectional nature enables tighter leakage control (<1 μA at VWM) versus bidirectional types.
What is the thermal resistance of P6SMB16AHE3/52, and how does it affect layout?
P6SMB16AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value assumes minimum recommended pad layout per Vishay's datasheet; reducing pad size increases thermal resistance and risks exceeding TJ = 150 °C during repetitive surges. Layout must maintain full copper exposure under both terminals and avoid thermal isolation - P6SMB16AHE3/52 performance degrades measurably if RθJA exceeds 110 °C/W.
