Product details
Overview
P6SMB16AHE3_A/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 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB16AHE3_A/H datasheet, P6SMB16AHE3_A/H pinout, P6SMB16AHE3_A/H application, or P6SMB16AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below VWM = 13.6 V and rapidly transitions to low-impedance conduction above VBR = 15.2–16.8 V to divert transient energy. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed for unidirectional operation, it uses cathode-band marking and exhibits 0.086 %/°C temperature coefficient of VBR, enabling predictable clamping behavior across -65 °C to +150 °C operating range. It meets MSL level 1 per J-STD-020 with 260 °C reflow peak and supports 100 A non-repetitive forward surge current (IFSM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for protected circuit. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Verified breakdown threshold ensuring precise overvoltage triggering without false trips. |
| VC (Clamping) | 22.5 V at 26.7 A - Peak voltage seen by protected load during 10/1000 μs transient; determines stress on downstream components. |
| PPPM | 600 W - Peak pulse power handling capacity with 0.01% duty cycle; enables robust protection against lightning and ESD surges. |
| IPPM | 26.7 A - Maximum peak pulse current supported at rated clamping voltage; defines surge current diversion capability. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient; informs PCB thermal pad design for sustained power dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring zero-failure reliability. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal cycling and humidity stress. |
| 600 W peak pulse power (10/1000 μs) | Provides immunity against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-induced popcorn failure or delamination. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns), improving protection margin for sensitive CMOS inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/52 | Same VWM (13.6 V), identical SMB package, but lower PPPM = 400 W and higher VC = 25.5 V at 19.3 A. | Limited to lower-energy transients; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom. |
| 1.5SMC16A | Same VWM/VBR specs, but larger SMC (DO-214AB) package (4.5 mm × 3.9 mm vs. 4.6 mm × 3.9 mm), higher thermal mass, RθJA ≈ 60 °C/W. | Better thermal performance in high-duty-cycle scenarios; requires larger PCB footprint. | Choose for industrial power supplies needing enhanced steady-state power dissipation beyond 5 W. |
Compared with SMAJ16A-E3/52 and 1.5SMC16A, P6SMB16AHE3_A/H delivers superior surge robustness (600 W vs. 400 W), tighter VC margin (22.5 V vs. 25.5 V), and automotive-grade qualification - making it optimal for space-constrained, high-reliability designs where layout area and AEC-Q101 compliance are critical.

FAQ
What is the clamping voltage of P6SMB16AHE3_A/H at its rated peak pulse current?
The P6SMB16AHE3_A/H has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured using the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed per the Vishay P6SMB datasheet revision 09-Jan-2024, page 2.
Is P6SMB16AHE3_A/H qualified for automotive applications?
Yes, P6SMB16AHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in the Vishay P6SMB datasheet section "Mechanical Data". It is approved for use in automotive subsystems including body control modules, infotainment power rails, and sensor signal conditioning circuits where zero-defect reliability is mandated.
What does the "_A/H" suffix in P6SMB16AHE3_A/H signify?
The "_A/H" suffix in P6SMB16AHE3_A/H denotes packaging configuration: "A" indicates unidirectional polarity, and "H" specifies 7-inch plastic tape-and-reel delivery with 750 units per reel. This matches the ordering information table on page 3 of the Vishay P6SMB datasheet (Document Number: 88370).
Can P6SMB16AHE3_A/H be used in bidirectional configurations?
No, P6SMB16AHE3_A/H is strictly unidirectional, as confirmed by its part number structure ("A" suffix) and the absence of "CA" designation. Bidirectional variants (e.g., P6SMB16CA) are separate devices with symmetrical breakdown in both directions; substituting P6SMB16AHE3_A/H in bidirectional roles would result in improper clamping on negative transients.
What is the thermal resistance junction-to-ambient for P6SMB16AHE3_A/H?
The typical thermal resistance junction-to-ambient (RθJA) for P6SMB16AHE3_A/H is 100 °C/W, measured on a standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal, as specified in the "Thermal Characteristics" table on page 3 of the Vishay P6SMB datasheet. This value guides PCB copper area design for sustained power dissipation.
