Product details
Overview
P6SMB16AHE3_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 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 rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB16AHE3_B/H datasheet, P6SMB16AHE3_B/H pinout, P6SMB16AHE3_B/H application, or P6SMB16AHE3_B/H equivalent, this AEC-Q101 qualified TVS diode delivers verified transient suppression performance in space-constrained SMB layouts, with RoHS-compliant matte tin terminals and MSL Level 1 moisture sensitivity rating.
Technical Context
The P6SMB16AHE3_B/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (VBR = 15.2–16.8 V), then clamping to ≤22.5 V at 26.7 A. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), enabling protection against ESD, inductive switching spikes, and lightning-induced surges.
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with RθJA = 100 °C/W and RθJL = 20 °C/W. The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and dissipates 5.0 W continuously on infinite heatsink at 50 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before significant conduction begins; sets operating margin below clamping threshold. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche onset range; defines minimum overvoltage triggering point for protection. |
| VC (Clamping) | 22.5 V at 26.7 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines safe voltage ceiling for downstream components. |
| PPPM | 600 W - Peak transient energy handling capability under standardized 10/1000 μs waveform; enables robust surge immunity per IEC 61000-4-5. |
| IPPM | 26.7 A - Corresponding peak pulse current at VC; used to size PCB trace width and verify system-level surge path integrity. |
| TJ max. | +150 °C - Maximum junction temperature; supports high-ambient environments such as engine control units and industrial motor drives. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
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 indicated by band; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to lower-potential side (e.g., ground or return path); defines directionality of clamping action. |
| Cathode | Reverse voltage input / Clamping output node | Connected to protected line (e.g., 12 V rail or signal trace); conducts during overvoltage to shunt current to anode. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables compliance with IEC 61000-4-5 Level 3 (1 kV surge) without derating in standard PCB layouts. |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving protection margin for 3.3 V/5 V logic and analog front-ends. |
| MSL Level 1 (260 °C peak reflow) | Supports single-pass lead-free reflow assembly without preconditioning or special handling. |
| AEC-Q101 qualification | Validates long-term reliability in automotive powertrain and body electronics applications subject to thermal cycling and vibration. |
| Glass passivated junction | Ensures stable leakage current (<1.0 μA at VWM) and consistent VBR over lifetime and temperature. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
|

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), identical SMB package, but lower PPPM = 400 W and higher VC = 26.0 V at 15.4 A. | Less robust for high-energy surges; suitable only where IEC 61000-4-5 Level 2 (0.5 kV) suffices. | Select SMAJ16A-E3/52 if cost sensitivity outweighs surge margin and board space allows no layout change. |
| 1.5SMC16A | Same VWM/VBR specs, but SMC (DO-214AB) package - 2.5 mm wider, requiring PCB footprint revision. | Higher thermal mass supports 1.5 kW peak pulse in derated configurations; not drop-in compatible. | Choose 1.5SMC16A only when enhanced thermal performance justifies redesigning pad layout and requalifying assembly. |
Compared with SMAJ16A-E3/52, P6SMB16AHE3_B/H delivers 50 % higher surge power handling and tighter clamping; versus 1.5SMC16A, it offers identical electrical performance in a smaller SMB footprint but with reduced thermal headroom for repetitive events.

FAQ
What is the maximum clamping voltage of the P6SMB16AHE3_B/H under standard test conditions?
The P6SMB16AHE3_B/H has a maximum clamping voltage (VC) of 22.5 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 26.7 A. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during a defined transient event. The P6SMB16AHE3_B/H maintains this clamping performance across its qualified temperature range and is validated for AEC-Q101 automotive use.
Is the P6SMB16AHE3_B/H suitable for automotive applications?
Yes, the P6SMB16AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" and "_B" suffixes - indicating RoHS-compliant construction and qualification to the AEC stress test standard. It is deployed in engine control units, body electronics, and infotainment power rails where transient immunity and long-term reliability are critical. The P6SMB16AHE3_B/H meets MSL Level 1 and supports lead-free reflow up to 260 °C.
What does the "_B/H" suffix mean in P6SMB16AHE3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB16AHE3_B/H series (applicable to P6SMB6.8A through P6SMB220A), while "/H" specifies packaging in 7-inch plastic tape-and-reel format with 750 units per reel. This ordering code confirms both automotive-grade reliability and logistics-ready configuration. The P6SMB16AHE3_B/H is not a bidirectional device - the "A" suffix indicates unidirectional polarity, with cathode marked by a band.
How does the P6SMB16AHE3_B/H compare to bidirectional variants like P6SMB16CA?
The P6SMB16AHE3_B/H is unidirectional and protects against positive-going transients only, with polarity-sensitive mounting (cathode to protected line). In contrast, P6SMB16CA provides symmetrical clamping for AC-coupled or floating lines. Both share identical VWM, VBR, and VC values, but P6SMB16AHE3_B/H exhibits lower leakage (<1.0 μA) and supports higher IFSM (100 A). Use P6SMB16AHE3_B/H where DC bias exists and polarity is fixed; choose P6SMB16CA for differential or AC signal paths.
What is the thermal resistance of the P6SMB16AHE3_B/H, and how does it affect layout design?
The P6SMB16AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under 5.0 W continuous dissipation, designers must ensure adequate copper area and avoid thermal bottlenecks. The P6SMB16AHE3_B/H's low RθJL makes it responsive to local pad cooling, supporting compact high-density layouts.
