Product details
Overview
P6SMB27AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 23.1 V stand-off voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA test current, 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform.
For engineers reviewing the P6SMB27AHE3_B/H datasheet, P6SMB27AHE3_B/H pinout, P6SMB27AHE3_B/H application, or P6SMB27AHE3_B/H equivalent, key selection criteria include clamping performance under IEC 61000-4-5 surge conditions, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior and low incremental surge resistance. Its response time is sub-nanosecond, enabling effective suppression of fast-rising ESD and lightning-induced transients.
The device is rated for repetitive 10/1000 μs surges at 0.01 % duty cycle, derated above TA = 25 °C per Fig. 2, and supports operating junction temperatures from –65 °C to +150 °C. It meets MSL Level 1 per J-STD-020 with LF peak of 260 °C and is RoHS-compliant and AEC-Q101 qualified (HE3 suffix with _B revision).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 23.1 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 25.7–28.4 V at IT = 1 mA - Verified avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 37.5 V at IPPM = 16.0 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC/MOSFET survivability. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs board-level thermal design. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD-HBM/MM. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (reverse-biased operation) | Connected to protected line (e.g., VBUS, signal trace); forms clamping path to cathode during overvoltage. |
| Cathode | Current exit terminal (reverse-biased operation) | Connected to ground or lower-potential rail; defines clamping reference and polarity-sensitive placement. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against severe transient threats including ISO 7637-2 Pulse 5a and IEC 61000-4-5 4 kV surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5B | Lower VWM (20.5 V), lower VC (38.9 V at 15.4 A), same SMB package and 600 W rating. | Better suited for 24 V nominal systems where tighter clamping margin is required below 24 V. | Select when system VCC tolerance demands clamping closer to nominal rail; verify VBR min ≥20.5 V avoids premature conduction. |
| 1.5SMC27A | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; RθJA ≈ 50 °C/W vs. 100 °C/W. | Higher thermal mass supports higher average power dissipation in non-automotive industrial designs. | Choose for legacy board layouts using SMC footprints or when junction temperature rise must be minimized under repetitive surges. |
Compared with SMAJ24A-E3/5B and 1.5SMC27A, P6SMB27AHE3_B/H offers AEC-Q101 qualification and MSL Level 1 compatibility out-of-box, making it the preferred choice for new automotive designs requiring zero-layout change and full process traceability.

FAQ
What is the clamping voltage of P6SMB27AHE3_B/H at its rated peak pulse current?
The P6SMB27AHE3_B/H has a maximum clamping voltage (VC) of 37.5 V at 16.0 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is guaranteed across temperature and represents the highest voltage the protected circuit will experience during a standardized surge event. The P6SMB27AHE3_B/H maintains this clamping performance while delivering 600 W peak pulse power, making it suitable for demanding IEC 61000-4-5 applications.
Is P6SMB27AHE3_B/H qualified for automotive use?
Yes, P6SMB27AHE3_B/H is AEC-Q101 qualified, as confirmed by the HE3 suffix and _B revision code in its ordering designation. It has undergone stress testing including high-temperature operating life (HTOL), temperature cycling (TCT), and ESD-HBM/MM per AEC-Q101 Rev D. This qualification makes P6SMB27AHE3_B/H appropriate for under-hood and cabin electronics where reliability under thermal and mechanical stress is critical.
What does the "_B" in P6SMB27AHE3_B/H signify?
The "_B" in P6SMB27AHE3_B/H denotes the AEC-Q101 qualification revision level for the P6SMB27AHE3 part, specifically indicating compliance with the B revision of Vishay's automotive qualification program. It is not a date code or package variant, but a formal certification marker tied to the HE3 base part number. This revision level applies to P6SMB6.8A through P6SMB220A devices and confirms full automotive-grade validation for P6SMB27AHE3_B/H.
How does the SMB (DO-214AA) package of P6SMB27AHE3_B/H compare thermally to larger packages like SMC?
The SMB (DO-214AA) package of P6SMB27AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on 0.2" × 0.2" copper pads, versus ~50 °C/W for the larger SMC (DO-214AB) package used in equivalents like 1.5SMC27A. This means P6SMB27AHE3_B/H requires more careful PCB thermal design-such as additional copper pour or thermal vias-to manage junction temperature during repetitive surges. However, its compact size supports high-density layouts where board space is constrained.
Can P6SMB27AHE3_B/H be used in bidirectional configurations?
No, P6SMB27AHE3_B/H is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA") and cathode-band marking. Bidirectional operation requires the CA variant (e.g., P6SMB27CA). Using P6SMB27AHE3_B/H in a bidirectional signal path would result in forward conduction during negative transients, potentially damaging the device or failing to suppress. Always match polarity: P6SMB27AHE3_B/H for DC rails with defined ground reference; P6SMB27CAHE3_B/H for AC or floating differential lines.
